DETERMINATION OF VITAMIN-B6, AVAILABLE LYSINE, AND EPSILON-PYRIDOXYLLYSINE IN A NEW INSTANT BABY FOOD PRODUCT

Selected jar and instant baby foods processed in 1985 and 1987 were analyzed for their vitamin B6, available lysine, and epsilon-pyridoxyllysine content in summer 1988. Jar and instant vegetable and beef were found to be higher in available lysine content but lower in vitamin B6 than banana products. Instant products were found to be higher in vitamin B6 than jar products. On a wet weight basis the instant products also contained higher amounts of available lysine than jar products. However, after adjustment for protein content, jar products were higher in available lysine than instant products. Baby foods processed in 1985 tended to be lower in vitamin B6 and available lysine content than products processed in 1987. Pyridoxyllysine was below detectable quantities in all of the baby foods analyzed in this study.
