Abstract
ATP inhibits enzymic browning of potato slices via formation of a reducing compound. Inhibition of browning by ATP was not affected by addition of dehydroascorbic acid, oxidized glutathione, or ascorbic acid oxidase. Therefore, formation of ascorbic acid is unlikely. Comparisons are made of browning inhibition by ascorbic acid, several thiols, dihydroxy-fumaric acid, and several carbonyl compounds.
