Abstract

Resumen del trabajo presentado a la "11th European Nutrition Conference (FENS)" celebrada en Madrid del 26 al 29 de octubre de 2011, MRP consumption reduced food intake and body weight of animals. The lower fecal excretion of AGEs observed after consumption of diets containing the fractions compared with the consumption of the complete bread crust would indicate increased absorption/transformation when compounds are administered in isolate form

Abstract

We investigate the effects of consumption of MRPs from the glucose-lysine model system heated 15°C-90 min on protein digestibility and its utilisation in young (3-week) and adult (12-week) rats. Nitrogen faecal excretion significantly increased after MRP consumption, especially during the third week. Protein digestibility was lower in both age groups studied, but the utilisation was unaffected. Parallelly, the nitrogen retention and its net utilisation for the entire experimental period did not vary. In young rats the faecal nitrogen exceeded the amount of ingested nitrogen coming from MRPs, suggesting that digestibility of undamaged nitrogen was affected. The same action is suspected in adult animals, but the results were not quantitatively conclusive, and therefore the effect should be moderate in this period. [ABSTRACT FROM AUTHOR]
