Influence of grapefruit juice intake on aflatoxin B1 (AFB1)-induced liver DNA damage was examined using a Comet assay in F344 rats given 5 mg/kg AFB1 by gavage. Rats allowed free access to grapefruit juice for 5 days prior to AFB1 administration resulted in clearly reduced DNA damage in liver, to 65% of the level in rats that did not receive grapefruit juice. Furthermore, rats treated with grap...

The demand of fruit juices is increasing day by day as a result of increasing health awareness among the people. Most of juice extraction processes are not producing satisfactory quantity and quality of juices. Enzymatic extraction of juices results in higher yield. The enzymes used are mainly pectinase, cellulase, hemicellase etc. Apart from promoting juice extraction, enzyme addition increase...

The mode of furfural accumulation was determined in aseptically filled containers of single-strength orange juice and concentrates during storage at six different temperatures. Results showed that furfural accumulated in orange juice more rapidly than in concentrates of 34,44, and 58 OBrix. There was 4 times the amount of furfural in orange juice (12 "Brix) than in concentrate (58 "Brix) stored...

samples were collected in sterile screw capped containers and processed within 30 minutes after the collection. Sugarcane juice was diluted 10-folds in phosphate buffered saline (pH 7.3) and bacterial count was determined by surface plating on blood agar and MacConkey agar plates. 1 For the isolation of Salmonella spp. and Shigella spp, sugarcane juice (50 mL) was inoculated into equal volumes ...

EDITORIAL SYNOPSIS The electrophoretic pattern of normal human gastric juice is described. The effect of autodigestion of gastric juice and of the peptic digestion of albumin is described. The fallacies involved in the study of gastric juice proteins where peptic digestion of the protein constituent has not been prevented are emphasized. In this study the gastric juice was neutralized within th...

In the past several years, concern about the presence of arsenic (As) in apple juice has grown greatly due to its publicity in the popular media. Arsenic can enter apple juice either naturally through environmental uptake by the apple trees or anthropogenically through the use of pesticides and/or contamination during processing.
