Introduction. Grapes are one of the most extensively cultivated crops in the world with almost 63 million tons produced worldwide, and the vast majority of the total grape production (75%) is used to produce wine (FAOSTAT ).Approximately 20% of the grapes (by weight) constitute the main winemaking by‐product, the grape or wine pomace (Laufenberg and others ).Cited by:

@article{osti_, title = {IRRADIATION-INDUCED CHANGES IN MILK FAT}, author = {Day, E A and Papaioannou, S E}, abstractNote = {Milk fat irradiated under reduced pressure exhibits a flavor atypical of that encountered through autoxidation, with a candle-like flavor component predominant.

Apparently, this flavor is attributable to hydroperoxides. Samples of beef and pork fats were irradiated under vacuum at seven doses ranging from to megarads. Of the components produced by irradiation, 41 were identified by gas chromatography and.

During processing, food aroma compounds are generated by enzymatic activity, fermentation, lipid oxidation, and thermal reactions (Maillard reaction, caramelization). While thermal technologies increase food safety, they also accelerate the aforementioned chemical reactions and thus induce several modifications in the macro- and by: 4.

Carbonyls do not seem to interfere with the absorption of dictary fat-soluble vitamin K. Carbonyl compounds such as are produced in beef due tomore» This conclusion is based on a study of plasma prothrombin times as:iffected by injections of carbonyls and steam distillates of irradiated beef extract.

The growth of Streptococcus thermophilus ST12 (ST12) in milk reconstituted from non-irradiated and irradiated at 10 kGy low-heat skim milk powders (RSM and irrRSM, respectively) at 40 °C was.

Isooctane-soluble carbonyl compounds in the lipid part and low-molecular-weight, acid-soluble carbonyls in the protein part of meat could be formed upon irradiation.

The 1-heptene and 1-nonene are the most important volatile components showing pronounced effects of irradiation (Akram, Ahn, & Kwon, ).

Abstract. The chief methods used for food preservation have been canning, salting, pickling, dehydration, and refrigeration. However, during the past 35 years, there has been widespread interest throughout the world in using ionizing radiation for this purpose, and as early asthe use of ionizing radiation was studied to preserve food using X rays to kill Trichinella spiralis in meat Cited by: 7.

The purpose of the irradiation is to disinfect fresh-chilled or frozen ground beef of the pathogenic organism, Escherichia coli OH7, to make these foods safer for human consumption.

The petition is specific to ground (comminuted) beef, either fresh-chilled or frozen, that is in its final packaging ready for cooking by consumers or food-service chefs or, in packaging ready for further.

Gamma treatment of β-glucan causes radiolysis of the glycosidic bond and reduction in the Mw of β-glucan fromg/mol in the case of non-irradiated sample to 62, 32, g/mol in case of sample irradiated at 10, 30, and 50 kDa that, in turn, lead to an improvement in its solubility from % to %, %, and % Cited by: 1.

Oregano essential oil at ppm showed the strongest effect in reducing the total carbonyl values. The total estimated carbonyl contents fall in the range of 1–3 nmol/mg protein for raw meat and up to 5 nmol/mg protein for cooked meat products [41,44,45,46].

However, the result from the DNPH method from several studies varied widely ( Cited by:   The peroxy radical undergoes chain scission and formation of carbonyl compounds. The photosensitivity has been evaluated of plastic sheet after different exposure times (, 5, 10 or 21 hr.).

In selecting agents to be included in the organic contaminants section of this report, a number of tabulations of organic contaminants detected in drinking water were examined.

From these lists, agents were selected that have been reported to be present in one or more drinking-water supplies at relatively high concentrations and for which there were data to suggest toxicity in man or animals.This type of rearrangement is crucial from a (i) coordination chemistry perspective since the phenol group remains available for coordination to a metal center, and (ii) the availability of aldehyde‟s carbonyl group for condensation reaction with amine containing compounds in the formation of the salen ligand as presented in Scheme Investigation of the starch components of a synthetic cereal species C.
