Abstract

Ascorbic Acid (Vitamin C) is very much important for the essential metabolic reactions in the body. This study was performed to investigate the impact of the Trivedi Effect®-Consciousness Energy Healing Treatment on the structural properties and isotopic abundance of vitamin C using LC-MS, GC-MS, and NMR spectroscopy. The test sample vitamin C was divided into two parts. One part was considered as control (no Biofield Treatment was provided), while second part received the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a famous Biofield Energy Healer, Mr. Mahendra Kumar Trivedi and termed as treated vitamin C. The LC-ESI-MS spectra of both the samples of vitamin C at the retention time 1.8 minutes exhibited the mass of the protonated molecular ion at m/z 176 [M+H]+ (calculated for C6 H9 O6 +, 177.04) in both the sample. Similarly, the fragmented ion peaks near m/z 158.91, 141.04, 129.19, and 95.10 correspond to the molecular formula C6 H7 O5 +, C6 H5 O4 +, C5 H5 O4 +, and C5 H3 O2 +, respectively were proposed for both the samples. The LC-MS based isotopic abundance ratio of PM+1 /PM in the treated vitamin C was significantly increased by 119.57% compared with the control sample. Thus, 13C, 2H, and 17O contributions from (C6 H8 O6 )+ to m/z 177.99 in the treated vitamin C were significantly increased compared with the control sample. On the contrary, the isotopic abundance ratio of PM+2 /PM in the treated vitamin C was significantly decreased by 15.07% compared with the control sample. Therefore, 18O contributions from (C6 H8 O6 )+ to m/z 179.05 in the treated vitamin C was significantly decreased compared with the control sample. T he GC-MS analysis indicated that the intensities for the mass peak at m/z 95 and 140 were significantly increased by 90.91% and 97.09%, respectively in the treated vitamin C compared to the control sample. The isotopic abundance ratios of PM+1 /PM (13C/12C or 2H/1H or 17O/16O) and PM+2 /PM (18O/16O) along with the mass peak intensities in the treated vitamin C might have altered the physicochemical properties compared to the untreated vitamin C. The increased isotopic abundance ratio of treated ascorbic acid would stronger the chemical bond, increase the stability, shift the chemical equilibrium constants, and alter the rate of metabolic reactions in the body. The Trivedi Effect®-Biofield Energy Healing Treated vitamin C would be very useful to design better nutraceutical/pharmaceutical formulations which might offer better therapeutic response against scurvy, cancer, obesity, cardiovascular, neurodegenerative, and autoimmune diseases.

Introduction

Ascorbic acid is also known as vitamin C (Figure 1) and is plenty available in the citrus fruits, tomatoes, red peppers, potatoes, animal liver, oysters, milk, etc. [1,2]. Vitamin C required in a certain range for the essential metabolic reactions both in plants and animals. It converts to ascorbate (ionized form) in neutral pH or above pH 5 in the cells of the body [3]. It is an electron donor acts as a potent water-soluble highly effective antioxidant, protect against oxidative stress [3-5]. It acts as a cofactor in many enzymatic reactions and few non-enzymatic reactions. Besides, it performs other physiological functions include the synthesis of carnitine, collagen, neurotransmitters;metabolism of microsome, and synthesis and catabolism of tyrosine in the body [2]. Vitamin C helps in the synthesis of collagen which is very important in the wound-healing and prevents bleeding from capillaries. It maintain the internal microenvironment determined by the redox balance, proven to be effective in the prevention and treatment of scurvy, obesity, cancer, hypertension, cardiovascular diseases (myocardial infarction, stroke, etc.), neurodegenerative diseases (Alzheimer’s disease), autoimmune diseases (rheumatoid arthritis), etc. [3,6-11] (Figure 1).

Vitamins are essential for our health and are present in almost all the foods we consume. Vitamin supplements such as multivitamin formulations are available for the prevention and treatment of vitamin deficiency diseases. Deficiency of vitamin C brings out the complications in the body, such as “scurvy” indicate bleeding gums, spongy gums, bleeding from all mucous membranes weakness, fatigue, and brown spots on the skin (thighs and legs). Other less noticeable signs but are still very serious of vitamin C deficiency such as weak immune system, gingivitis, slow wound healing, dry and splitting hair, nose bleeding, leaky gut, autoimmune disease, swollen and painful joints, etc. Long term vitamin C deficiency leads to cancer, high blood pressure, stroke, gallbladder disease, atherosclerosis, etc. [7-9]. As per the Food and Nutrition Board of the National Academy of Sciences; the tolerable upper intake level (UL) of vitamin C is 2,000 mg/day. Relatively large doses of vitamin C may cause indigestion, diarrhoea, headache, skin rashes, fatigue, disturbed sleep, haemochromatosis, suppress the production of progesterone from the corpus luteum in healthy subjects [2,12]. Low plasma concentrations are reported in patients with diabetes, infections, and smokers, but the relative contribution of diet and stress to these situations is uncertain [14].

Vitamin C degrades during the packaging, storage, and cooking of blended foods (maize,soya,etc.) is the prime limitations associated with it. Some of the research studies confirmed that exposure to air and storage temperature condition significantly affects the stability of the vitamin C. The stability of vitamin C is the major issue during processing,storage, and cooking [13-16]. Dissolution,absorption, bioavailability, and stability of a pharmaceutical compound depend upon the physicochemical properties [17], and to improve the quality of these parameters is a constant approach by the pharmaceutical scientists. The Trivedi Effect®-Consciousness Energy Healing Treatment is an economical approach and has the significant impact on the physicochemical, spectral, and thermal properties of pharmaceuticals and nutraceuticals, through the possible mediation of neutrinos [18-20]. It is also proved that with the help of Biofield Energy Healing Treatment (the Trivedi Effect®) significantly altered the isotopic abundance ratios of the pharmaceutical compounds [21,22].

“Biofield Energy” the electromagnetic energy surrounded by every human body, which can discharge the electromagnetic energy in the form of bio-photons, generated by the continuous movement of the electrically charged particles (ions, cells, etc.) inside the body. The Biofield Energy Healing experts have the capability to harness the energy from the environment or the “Universal Energy Field” and can transfer into any living or non-living object(s), this process is called Biofield Energy Healing Treatment [23-25]. The Biofield based Energy Therapies have been reported to with significant outcomes against various disease [26]. The National Center of Complementary and Integrative Health has recognized and accepted Energy Healing Treatment as a Complementary and Alternative Medicine health care approach in addition to other therapies, medicines, and practices such as yoga, Qi Gong, Tai Chi, hypnotherapy, Reiki, etc. [27,28]. These therapies have been accepted by most of the U.S.A. population with several advantages [28]. The Trivedi Effect®-Consciousness Energy Healing Treatment had been widely accepted treatment and reported scientifically with significant outcome in different fields of pharmaceuticals and nutraceuticals [18-22,29-31], materials science [32,33], agricultural science [34,35], microbiology [35,36], cancer research [37,38], etc. The isotopic abundance ratios of PM+1/PM and PM+2/PM were significantly altered in the Biofield Energy Treated pharmaceutical compounds such as 1,4-dichlorobenzene [21], o-and m-nitrophenol [22],4-bromoaniline [39], and 2,4-dichlorophenol [40]. Thus, the Trivedi Effect® can be an economical approach and solution to the practical problem of thermal stability of vitamin C by altering the isotope composition to improve the physicochemical parameters for designing better pharmaceuticals and nutraceutical formulations. The stable isotope ratio analysis has various applications in different scientific fields for considerate the isotope effects resultant from the variation of the isotopic composition of the molecule [41,42]. Isotope ratio analysis can be performed by using the conventional mass spectrometry (MS) techniques such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) in low micromolar concentration with sufficient precision [41,43]. Hence, LC-MS, GC-MS, and NMR (Nuclear Magnetic Resonance) were used in this study to characterize the structural properties of the treated and untreated vitamin C. Consequently, LC-MS based isotopic abundance ratio analysis of PM+1/PM (2H/1H or 13C/12C or 17O/16O)and PM+2/PM (18O/16O) in both of the samples of vitamin C were aimed to investigate the impact of the Trivedi Effect® on the isotopic abundance ratio in vitamin C.

Materials and Methods

Chemicals and reagents

The test sample vitamin C (Alfa Aesar) and other chemicals, i.e, acetonitrile (Merck), formic acid (Merck), methanol (advent), purified water (Evoqua) were of analytical grade purchased in India.

Consciousness energy healing treatment strategies

The test sample of vitamin C was divided into two parts and termed as control and treated vitamin C. The control sample did not receive the Biofield Energy Treatment; while the treated vitamin C received the Trivedi Effect®-Consciousness Energy Healing Treatment by a famous Biofield Energy Healer, Mr. Mahendra Kumar Trivedi (USA). Further, the control sample was treated with a “sham” healer who did not have any knowledge about the Biofield Energy Treatment. The Biofield Energy Treated and control samples were kept in sealed conditions and characterized using sophisticated analytical techniques.

Characterization

Liquid chromatography-mass spectrometry (lc-ms) analysis and calculation of isotopic abundance ratio: The LC-MS analysis of both the vitamin C samples were carried out with the help of LC-Dionex Ultimate 3000, MS-TSQ Endura, USA [21,22]. The column used here was a reversed phase Zorbax SB-C18 100X4.6mm, 3.5µm, maintained at 40˚C. 10 µL of vitamin C solution in methanol was injected and the analyte was eluted using 2 mM ammonium formate in water with 0.5% formic acid (mobile phase A) and acetonitrile (mobile phase B) pumped at a constant flow rate of 0.6 mL/min. Chromatographic separation was achieved using gradient condition as follow: 0.1 min-5%B, 5.0 min-5%B, 15.0 min-60%, 20.0 min-75%B, 25.0 min-95%B, 35.0 min-95%B, 40.0 min-5%B and 45.0 min-5% B and the total run time was 45 min. Peaks were monitored at 250 nm using the PDA detector with electro spray ionization (ESI) in positive mode. The peak area%, total ion chromatogram and mass spectrum of the individual peak which was appeared in LC were recorded.

The natural abundance of each isotope (C,O,and H) was predicted comparing the height of the isotope peak to the base peak. The natural isotopic abundance values of the common elements are obtained from the literature [42,44-46]. The isotopic abundance ratios (PM+1/PM and PM+2/PM) for the control and Biofield Energy Treated vitamin C was calculated [21,22].

% change in isotopic abundance ratio = [(IARTreated-IARControl)/IARControl ]x100

Where IARTreated = isotopic abundance ratio in the treated vitamin C and IARControl=isotopic abundance ratio in the control sample.

Gas chromatography-mass spectrometry (GC-MS) analysis:

GC-MS of both the samples of vitamin C were analyzed with the help of Agilent 7890B Gas chromatograph and coupled to a quadrupole detector with pre-filter (5977B,USA) was operated with electron impact (EI) ionization in positive mode.Oven temperature was programmed from 50°C (1 min hold) to 150°C @ 20°C/min to 200°C (6 min hold) @ 25°C/min to 280°C@ 20°C/min (12 min hold) [22].

The total ion chromatogram and mass spectrum of the individual peak (appeared in GC-MS) were recorded. The % change in GC-MS mass peak intensity (I) was calculated using the following equation 1:

% change in peak intensity = [ITreated-IControl]/IControl×100 (1)

Where IControl and ITreated are the peak intensity of the control and treated vitamin C, respectively.

Nuclear magnetic resonance (nmr) analysis: 1H and 13C NMR analysis of the vitamin C was conducted at 400 MHz and 100 MHz, respectively using Agilent-MRDD2 FT-NMR spectrometer at room temperature using TMS as an internal standard [21,22]. Chemical shifts (δ) were in parts per million (ppm) relative to the solvent’s residual proton chemical shift (DMSO-d6,δ=2.50 ppm) and solvent’s residual carbon chemical shift (DMSO-d6 , δ = 39.52 ppm).

Results and Discussion

Liquid chromatography-mass spectrometry (LC-MS)

The LC chromatograms and mass spectra of both the samples of vitamin C are shown in Figures 2 and 3, respectively.

Figure 2: Liquid chromatograms of the control and treated vitamin C.

Figure 3: Mass spectra of the control and treated vitamin Cat Rt 1.8 minutes.

The LC chromatograms of both the sample of vitamin C revealed the presence of a single peak at the retention time (Rt) 1.8 minutes (Figure 2). Thus, the results indicated that the polarity of the vitamin C remained the same in both the sample.

As per the literature LC-ESI-MS spectrum in negative ion mode produced a molecular mass peak at m/z 175.4 [47]. The ESI-MS spectra of both the samples of vitamin C (Figure 3) at the retention time 1.8 minutes exhibited the mass of the protonated molecular ion at m/z 176.98 [M+H]+ (calculated for C6 H9 O6+,177.04) in the control sample and at m/z 176.99 [M+H]+ in the Biofield Energy Treated vitamin C, along with the fragment ion peaks near m/z 158.91,141.04,129.19, and 95.10 which were corresponded to the molecular formula C6 H7 O5+,C6 H5 O4+,C5 H5 O4+,and C5 H3 O2+, respectively in both the samples (Figure 3,4).

Figure 4: Proposed fragmentation pathway of vitamin C.

The ESI-MS spectra of both the samples showed the mass of the molecular ion peak at m/z 176.98 (C6 H8 O6+) showing relative intensity of 100%. The theoretical calculation of PM+1 for vitamin C were presented as below:

P(13C)=[(6x1.1%)x100% (the actual size of the M+ peak)]/100% = 6.6%

P(2H) = [(8 x 0.015%)x100%]/100%= 0.12%

P(17O) = [(6x0.04%)x100%]/100% = 0.24%

PM+1 , i.e.13C, 2H, and 17O contributions from (C6 H8 O6)+ to m/z 177.99 = 6.96%

From the calculation, it was found that 13C and 17O have major contribution to m/z 177.99.

Similarly, the theoretical calculation of PM+2 for vitamin C were presented as below:

P(18O) = [(6x0.20%)x100%]/100% = 1.2%

PM+2 , i.e.18O contributions from (C6 H8 O6)+ to m/z 179.05 = 1.2%

From the above calculation, it has been found that 18O have major contribution to m/z 179.05.

The isotopic abundance ratio analysis of vitamin C in the control and Biofield Energy Treated samples were calculated for its molecular mass at m/z 176.98. PM (m/z 176.98), PM+1 (m/z 177.99), and PM+2 (m/z 179.05) were achieved from the observed relative peak intensities of [M+], [(M+1)+], and [(M+2)+] peaks, respectively in the ESI-MS spectra and are presented in Table 1. The % change of the isotopic abundance ratios (PM+1/PM and PM+2/PM) in the treated vitamin C compared with the control sample are shown in Table 1. The isotopic abundance ratio of PM+1/PM in the Biofield Energy Treated vitamin C was significantly increased by 119.57% compared with the control sample (Table 1). So, 13C, 2H, and 17O contributions from (C6 H8 O6)+ to m/z 177.99 in the Biofield Energy Treated vitamin C were significantly increased compared with the control sample. The isotopic abundance ratio of PM+2/PM in the treated vitamin C was significantly decreased by 15.07% compared with the control sample (Table 1). So,18O contributions from (C6 H8 O6)+ to m/z 179.05 in the Biofield Energy Treated vitamin C were significantly decreased compared with the control sample.

Gas chromatography-mass spectrometry (GC-MS) analysis

The GC chromatograms of the control and Biofield Energy Treated samples of vitamin C showed the presence of several chromatographic peaks (Figure 5).

Figure 5: The GC-MS chromatogram of the Control (A) and treated (B) sample of L-vitamin C.

The retention times of the Biofield Energy Treated vitamin Care similar to those of the control sample. Parent molecular peak of vitamin C did not observe in any of the mass spectra of control and Biofield Energy Treated samples. Molecular fragments at m/z 95.0 [M+] (calculated for C5 H3 O2 +,95.01) and m/z 140.0 [M+] (calculated for C6 H4 O4 +,140.01) of the control (Figure 5A) and Biofield Energy Treated (Figure 5B) vitamin C were proposed for Rt of 5.64 minutes from both the mass spectra. The results indicated that the polarity of both samples is same, but the mass peak intensities are widely different in the Biofield Energy Treated vitamin C compared to the control sample. The intensities for the mass peak at m/z 95 and 140 were significantly increased by 90.91% and 97.09%, respectively in the Biofield Energy Treated vitamin C compared to the control sample (Table 2). The mass peak intensities influence the isotopic abundance ratio, which was well supported by the LC-MS, based isotopic abundance ratio analysis.

Nuclear Magnetic Resonance Spectroscopy (1H &13C NMR)

The 1H and 13C NMR of the control and Biofield Energy Treated vitamin C were carried out, and the results are reports in Table 3. The characteristic proton signals for aromatic protons, -CH2 , -CH, and -OH groups of vitamin C in the 1H NMR of spectra of both the control and Biofield Energy Treated samples was described in Table 3. Similarly, the characteristic carbon signals for -C=O, quaternary carbon (aromatic), -CH (aromatic and aliphatic),-CH2 (aliphatic), -COH (aromatic and aliphatic) groups of vitamin C in the 13C NMR of spectra of the both the control and Biofield Energy Treated samples were described in Table 3. The experimental data well matched with the literature data [48]. The results indicated that there was no such significant alternation in the characteristic proton and carbon signals for vitamin C in the 1H and 13C NMR spectrum of the Biofield Energy Treated vitamin C compared with the control sample.

Finally, LC-MS, GC-MS, and NMR study confirmed the structure of vitamin C. The LC-MS based isotopic abundance ratios of PM+1/PM (2H/1H or 13C/12C or 17O/16O) and PM+2/PM (18O/16O) in the Biofield Energy Treated vitamin C were significantly altered compared to the control sample. Modern physics explained that neutrinos change identities which are only possible if the neutrinos possess mass and have the ability to interchange their phase from one phase to another internally. Therefore, the neutrinos have the ability to interact with protons and neutrons in the nucleus, which indicated a close relation between neutrino and the isotope formation [20,44,45]. The altered isotopic composition in the molecular level of the Trivedi Effect® Consciousness Energy Healing Treated vitamin C might be due to the alteration in neutron to proton ratio in the nucleus. It can be hypothesized that the changes in isotopic abundance could be due to changes in nuclei possibly through the interference of neutrino particles via the Trivedi Effect®-Consciousness Energy Healing Treatment.The natural abundance and relative proportion of the stable isotopes in organs and tissues significantly affected by the environment, climate, etc.The isotopic abundance ratios 2H/1H, 13C/12C,17O/16O,and 18O/16Owould highly influence the atomic bond vibration of treated ascorbic acid [49]. The increased isotopic abundance ratio of the Consciousness Energy Healing Treated ascorbic acid would stronger the chemical bond, increase the stability, shift the chemical equilibrium constants, and alter the rate of metabolic reactions in the body.

Conclusions

The experimental results revealed that the Trivedi Effect® Consciousness Energy Healing Treatment has the significant impact on the isotopic abundance ratios and mass peak intensities of vitamin C. The LC-MS based isotopic abundance ratio of PM+1/PM in the treated vitamin C was significantly increased by 119.57% compared with the control sample. Thus, 13C,2H, and17O contributions from (C6 H8 O6)+ to m/z 177.99 in the treated vitamin C were significantly increased compared with the control sample.On the contrary, the isotopic abundance ratio of PM+2/PM in the treated vitamin C was significantly decreased by 15.07% compared with the control sample.Therefore, 18O contributions from (C6 H8 O6)+ to m/z 179.05 in the Biofield Energy Treated vitamin C was significantly decreased compared with the control sample. The GC-MS indicated that the intensities for the mass peak at m/z 95 and 140 were significantly increased by 90.91% and 97.09%, respectively in the treated vitamin C compared to the control sample. The isotopic abundance ratios of PM+1/PM (2H/1H or 13C/12C or 17O/16O) and PM+2/PM (18O/16O) along with the mass peak intensities in the Biofield Energy Treated vitamin C might have altered the physicochemical properties compared to the untreated vitamin C. The isotopic abundance ratios 2H/1H,13C/12C,17O/16O, and 18O/16O highly influence the atomic bond vibration of the Biofield Energy Treated ascorbic acid. The increased isotopic abundance ratio of ascorbic acid would stronger the chemical bond, increase stability, shift the chemical equilibrium constants, and alter the rate of metabolic reactions in the body. The Trivedi Effect® treated vitamin C would be very useful to design better nutraceutical/pharmaceutical formulations which might offer better therapeutic response against scurvy, cancer, obesity, cardiovascular diseases (myocardial infarction, stroke, etc.), hypertension, neurodegenerative diseases (Alzheimer’s disease), autoimmune diseases (rheumatoid arthritis), etc.

Removal of Acid Beverage Flocs in Crystal Sugar by Adsorption Column Chromatography: Preliminary Study with Adsorbent Resin

The sugar industry has been facing some problems with white sugar intended for soft drinks production. Some studies have been demonstrated the sugar could be source of insoluble substances technically called by Acid Beverage Flocs (ABF). It appears during the beverage production; however, the flocs are easily disappearing with shaking. This may be related to raw material the sugarcane quality and, consequently, with the efficiency of the juice clarification process, since if there is no adequate juice treatment. The sugarcane commonly has lower quality and higher intensity of impurities, such as proteins, wax, minerals and colloids. The sugar industries are implementing solutions to reduce the amount of impurities through using technologies like ionic resins to removal of color, odor or undesirable taste. It could transform raw sugar in refined or white sugars. The aim of this work was evaluate the efficiency of purification of sugar solution with chromatographic adsorption system. We observed that the color reduction was around 69% and an intensive reduction in turbidity of sugar aqueous solution. There were variation on sucrose and increase on reducing sugars (glucose and fructose) contents. It is possible to conclude that the process could be efficient to reduce the color (MAU color), turbidity and ABF into sugar solutions.

A Study to Evaluate Aflatoxin Contamination in Food from Gauteng Province

Aflatoxins (AFs) and their producers have been found to be problematic and is still an issue. This is due to their role in influencing food quality, health and economy loss. In maintaining good food quality, minimize AFs occurrence and its deleterious effects, it is essential that issues relating to mycotoxin production and contamination are monitored, and addressed on a regular basis. This will proffer suggestions for immediate actions to be taken, in order to achieve and maintain regulatory limit before situations are out of control. Hence the case study to evaluate the concentration of AFs in food, by way of thin layer chromatography and high performance liquid chromatography was attempted. This is to monitor concentrations of the emerging mycotoxin in relation to international regulatory limits. Concentrations levels ranging 0.06 - 77.97 ppb was observed, (mean: 16.8 ppb) and measured out in the food samples of study, exceeding the ISO limits (0.05 ppb). This calls for proper monitoring of pre and postproduction stages in food, by employing easy to use chromatographic techniques as a routine process to screen and ascertain concentrations do not exceed regulatory limits.

Investigation of Naturally Occurring Fumonisin B1 and Glycated Fumonisin B1 in Korean Feedstuffs

Mycotoxins are potentially dangerous contaminants of livestock feeds. In this study, we measured the levels of fumonisin B1 and glycated fumonisin B1 in feedstuffs and then investigated the ability of the extrusion heating regimen to convert the most prevalent mycotoxin contaminant, fumonisin B1 , to a less toxic glycated form. All feed samples were analyzed with fully validated methods. All measured concentrations of fumonisin B1 were below harmful thresholds, including European Union-recommended levels or US Food and Drug Administration action levels.

Because fumonisin B1 was highly contaminated mycotoxin in our present investigation and fumonisin B1 has been shown to be less toxic following Maillard type reaction with reducing sugar, we examined the formation of fumonisin B1 derivatives by Maillard reaction under extrusion process conditions. We employed a variety of tandem mass spectrometric methodologies to selectively detect fumonisin B1 derivatives and to elucidate their structures partially. We found that compounds of m/z 736 were more likely artifacts or side reaction products rather than glycation products. N-(carboxymethyl) fumonisin B1 of m/z 780 and other major glycation products of m/z 794 and 810 were not detected, and only negligible amounts of methylene fumonisin B1 was found in 10 extruded feed samples. Therefore, either the tested extrusion conditions did not induce fumonisin B1 glycation or the glycation products simply could not be detected by the method employed in this study.

Determination of HMF in Some Instant Foods and Its Biodegradation by Some Lactic Acid Bacteria in Medium and Food

The aims of this study were to determine HMF level in some foods and to reduce their level by biodegradation. Coffee whitener, cappuccino, hot chocolate, instant coffee, instant powdered mix (coffee, coffee whitener and sugar) and aromatized cocoa were subjected to HMF analysis in the scope of this study. The HMF determination of samples was carried out using a high performance liquid chromatography. Color properties of the samples were determined according to standard procedures and their relations with HMF content were also investigated. The biological degradation of HMF with lactic acid bacteria was also studied with broth media and a model food system (reconstituted milk).The average HMF levels were 12.59 mg/kg for coffee whitener, 572.49 mg/ kg for cappuccino, 660.29 mg/kg for hot chocolate, 1804.91 mg/kg for instant coffee, 871.56 mg/kg for instant powdered mix and 980.94 mg/kg for aromatized cocoa. The addition of lactic acid cultures reduced the HMF content of the samples. HMF levels of broth media and model food inoculated with lactic acid bacteria (L. lactis, L.bulgaricus, L. cremoris) decreased about 25 % as a result of HMF biodegradation.

An Integrated Analysis of the Musa Paradisiaca Peel, Using UHPLC-ESI, FT IR and Confocal Microscopy Techniques

When the banana (Musa paradisiaca) peel was subject of enzymatic hydrolysis with cellulase and hemicellulase, only glucose was obtained. Images from banana peel, using confocal laser scanning microscopy, demonstrate that the cellulose is the main structural compound. Fatty acids, phenolic and other compounds were detected from the organic residual extract, and characterized by means of NMR, FT-IR and UHPLC-MS techniques. The presences of these compounds were corroborated through a steam distillation. Under this condition, banana peel could have potential applications in the food field, where could be used to improve some procedures such as the obtaining of banana vinegar.

Structural Characterization of Bamboo Lignin Isolated With Formic Acid and Alkaline Peroxide by Gel Permeation Chromatography and Pyrolysis Gas Chromatography Mass Spectrometry

Fractionation is an effective technology to maximize the utilization of lignocelluloses for the production of chemicals and materials. In this case, bamboo was subjected to a two-step fractionation process based on the concept of biorefinery: (a) formic acid treatment at boiling point under atmospheric pressure for 2 h, and (b) post treatment with alkaline hydrogen peroxide solution containing 1% NaOH and 1% H2 O2 at 80 ºC. The combination of formic acid delignification and alkaline hydrogen peroxide degradation achieved an effective removal of both lignin (delignification rate 94.9%) and hemicelluloses (removal rate 87.4%) from bamboo, producing cellulose rich pulp, formic acid lignin and sugars. To investigate the structural modification of lignin during the fractionation process, the residual lignin in the treated samples was isolated and characterized with multiply techniques including gel permeation chromatography, pyrolysis gas chromatography mass spectrometry, Fourier-transform infrared spectroscopy, etc. The relative ratio of S/G was 1.63 for bamboo milled wood lignin (L1), whereas the lignin isolated from the formic acid treated cellulose-rich fraction (L2) presented a chromatograph similar to that of L1 but had a lower S/G ratio of 1.28. This indicated that a preferential removal of S units during the formic acid fractionation process. In addition, alkaline hydrogen peroxide treatment resulted in more removal of S units, as indicated by a lower S/G ratio of 0.71.

Volatile Compound Profiles by HS GC MS for the Evaluation of Postharvest Conditions of a Peach Cultivar

Volatile Organic Compounds (VOCs) profile of foods obtained by Gas Chromatography/Mass Spectrometry (GC/MS) can be considered a potent tool of food products quality changes occurring as a result of different processing, such as ripening and deterioration. The aim of the present study was the evaluation of volatiles profiles of peaches (cv Springcrest) during their storage in conditions similar to those of long distance transport that normally these products undergo before being placed on market. We investigated control sample (no stored fruit) and peaches stored in cardboard boxes wrapped in heat-sealed HD polythene bags, both in normal and modified atmosphere (0% and 23% CO2 ) after 1 and 8 days of storage at 4°C. GC/MS analysis of these samples allowed the identification of a total of 115 VOCs.

The comparison of the VOCs profile of the three peach samples (control, normal atmosphere and 23% CO2 ) shows that fruits packaged in normal atmosphere released a greater amount of esters of medium chain fatty acids, such as ethyl nonanoate and ethyl dodecanoate. On the other hand, fruits stored in normal atmosphere and modified atmosphere after 8 days of storage (increased concentration of CO2 in packs) released a greater amount of esters of long chain fatty acids, such as ethyl hexadecanoate.
