Evaluation of aflatoxin-related products from ozonated corn
… the chemical reaction between aflatoxin and gaseous ozone. Ozonation (12-13 wt%) totally degraded aflatoxin B1 in a model system. Conversion of aflatoxin into polar compounds was observed during ozonolysis of 100 µg aflatoxin B1 in an aqueous environment and in solid form. Seven intermediate …

Effects of Disinfectants and Anti-browning Agents on the Shelf-Life of Cauliflower Florets
… and contact times. Chemicals included gaseous ozone, calcium chloride, citric acid, ascorbic acid, chlorine dioxide and sodium hypochlorite. The combination of 250 ppm ascorbic acid and 500 ppm citric acid pre-wash (30 seconds) and a 100 ppm hypochlorite wash (30 seconds, with pH …

Fundamental Studies of Two Important Atmospheric Oxidants, Ozone and Hydroxyl Radical, Reacting with Model Organic Surfaces
… little is known about the reaction dynamics of gaseous oxidants with organic compounds found in the atmosphere. The first step of the reaction between gaseous ozone and solid pentacene was investigated using Reflection Absorption Infrared Spectroscopy (RAIRS). Ozone was found to add to pentacene …
