Digestibilidad gastrointestinal in vitro de almidón y proteína en harina de cañihua (Chenopodium pallidicaule Aellen) variedad Cupi

Abstract

Cañihua is one of the little-known Andean grains, that has been shown to have equal or better nutritional and functional properties than those commonly known as quinoa and amaranth. The nutritional composition of cañihua is: 15.6 more less 0.21 percent of protein, 8,54 more less 0,16 percent of fat, 6,74 more less 0,64 percent of crude fiber and 2,64 more less 0,15 percent of ash. The content of water-soluble sugars was determined with the method of 3.5 dinitrosalicylic acid (DNS) and total starch, resistant starch was measured with the Glucose Determination Kit (GAGO-20). Regarding the kinetics of starch hydrolysis in cañihua seed: the ratio slowly hydrolyzed starch to maltose is higher than of rapidly hydrolyzed to maltose starch. As protein concentrate of cañihua was proven by SDS-PAGE electrophoresis that it is digestible by enzymes such as pepsin and pancreatin, so that cañihua is a good source of digestible protein.
