Evaluación del Efecto Antihiperglucémico del Bagazo de Naranja (Citrus sinensis var.Valencia) en Estudios in vitro.

Abstract

The objective of the present work was evaluate the anti-hyperglycemic effect of the orange bagasse (Citrus sinensis Var. Valencia), with in vitro studies. The orange bagasse was dehydrated to 70 ºC during 7 h. After, the soluble and insoluble fiber content was quantified. In the in vitro studies was evaluated the capacity that has the fiber to catch glucose in a model system (dialysis membrane). The fiber was incubated with different glucose concentrations, and glucose content of solutions was quantified. Also, the capacity that has the fiber to inhibit the activity of the ?-amylase enzyme was determined, using starch like substrate. The three dehydrated bagasse flours display a high percentage of soluble fiber that represents more than 55% and the percentage of insoluble fiber was smaller of 3%. In the same way, was observed that the three different types of orange bagasse flour handled in this study; they absorb glucose, they slow down diffusion of glucose through a dialysis membrane and have activity to inhibit the activity of ?-amylase.
