Xanthine Accumulation during Hypoxanthine Oxidation by Milk Xanthine Oxidase [PDF]
European Journal of Biochemistry, 1973 Accumulation of xanthine as well as uric acid, was found as a result of hypoxanthine oxidation by xanthine: oxygen oxidoreductase from milk. The ratio xanthine/uric acid increases with hypoxanthine concentration, and decreases with the enzyme concentration and the reaction time.

Food Chemistry International, EarlyView.After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...

Nonthermal Food Processing Technologies: A Comprehensive Review
Future Postharvest and Food, EarlyView.The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...
