The objective of this study was to determine the level of preservatives and microbiological loads in various brands of commercially available chili bo (paste). Fifteen different brands of chili bo obtained from the local market and hypermarkets were analyzed for pH, moisture and benzoic acid content, microbiological loads (aerobic, anaerobic, aerobic spores, and fungi), and thermophilic microor...
In 1877 Salkowski (1) noted the presence of a reducing substance in the urine of rabbits following the administration of sodium benzoate. Later Magnus-Levy (2) reported that this substance was benzoyl glycuronic acid and stated that less was found in the urine of rabbits than in the urine of dogs and sheep. At the present time it is the general assumption that rabbits detoxicate ingested benzoi...
Hydrogenation of benzoic acid using monoand bimetallic catalyst of Ru, Pd, Co, and Re yielded different products. It was observed that 5% Ru/C was an active catalyst for hydrogenation of both aromatic ring and carboxylic group, while Pd/C catalyst hydrogenated only aromatic ring. Ru-Sn/Al2O3 is a chemoselective catalyst for hydrogenation of –COOH group of benzoic acid.
