Resumen o descripción

The aim of this study is to determine the effect of the polyphenol structure (Procyanidin B2, (+)- Catechin and chlorogenic acid), pectin (high (HM), low methoxyl (LM)), the acidifying medium (citric acid and malic), pH (3 and 4) and the presence of ions (KCl) on the formation of pectin-polyphenol complex in a model solution system that simulates a functional beverage matrix; and the impact of the formation of this complex in the biological effect of the beverage. The evaluation of the formation of pectin-polyphenol complex was performed by determining the% inhibition of DPPH radical and free polyphenols profile by HPLC in model solutions. The evaluation of the biological effect was performed by postprandial testing in mice Balb/c which were induced hyperglycemia with maltose. The results were analyzed by analysis of variance (ANOVA) with a 95% confidence. It was determined that the physicochemical parameters such as pH, the presence of ions and type of acidifying if they have a significant effect on the formation of pectin-polyphenol complex, and that the impact of these parameters depend on both the functional groups of the polyphenol as pectin that are in solution. Biological tests show that it is possible to determine the impact of pectin-polyphenol complex functional properties of a food, this allows us to lay the groundwork for the development of new functional foods where it is relevant to interactions with other nutraceuticals components of a food matrix
