Protein content and some starch characteristics in amaranth (Amaranthus spp.) seeds cultivated in Chillan, Chile

Abstract

The protein content and characteristics of the starch such as water absorption index, water solubility index and swelling capacity in the seed were evaluated in twelve genotypes of amaranth cultivated in Chillán, Chile. A randomized complete block design with twelve treatments and four replications was used. The average protein content obtained was 16,8% and fluctuated between 15,4% and 18,2%. Averages of 2,36, 6,07% and 2,5 for water absorption index, water solubility index and swelling power, respectively, were determined. Statistically significant differences were found between the genotypes for all of the variables that were studied, except for water absorption index.
