Abstract

VALENZUELA, Luz A; ORTIZ, Blanca L  and  PEREZ, Clara E. Comparative study of the metabolic effect of arepas enriched with pectin extracted from guava (Psidium guajava L.) or commercial citrus pectin. Rev.Colomb.Quim. [online]. 2013, vol.42, n.3, pp.302-325. ISSN 0120-2804.

Guava (Psidium guajava L.), contains up to 8.5% total dietary fiber, of which 1.9% is soluble fiber, which makes this tropical fruit a good source of pectin, soluble fiber whose consumption decreases intestinal absorption of lipids and protects against cardiovascular disease. In this work the metabolic effect of consumption of corn arepas enriched with 10% pectin for 20 days, in the lipid profile and blood glucose in a group of 75 university students was evaluated; it was also seek to establish the differences in the effect observed when within the formulation of the arepas a commercial citrus pectin was added compared to when pectin extracted from guava (Psidium guajava L.) was used. The comparison of the glucose and lipid levels before and after treatment showed that with consumption of those arepas favorable changes for the health of the individuals were generated, since there was a statistically significant decrease in serum levels of total cholesterol, LDL cholesterol and glucose. Although there is a trend in the results showing an average increase in HDL cholesterol after consumption of products with the two types of pectin, there is no statistical evidence to infer that the change is significant. Similarly, the results indicate no difference between the effects generated by the two types of pectin, except for the greatest decrease in triglyceride levels achieved when commercial pectin was added.

Keywords : Dietary fiber; guava pectin; citrus pectin; arepas; hypolipidemic effect.
