Total phenolic, antioxidant activity and physic-chemical properties of waxy pigmented and non-pigmented rice in Cambodia

Abstract

This study determined the physicochemical properties, total phenolic content, and antioxidant activity of waxy pigmented and non-pigmented rice varieties in Cambodia. The results showed that, waxy pigmented rice has 2.1% for amylose, 8.31% for crude protein, 2.67% crude fat, 0.77% crude fiber, 0.59 % crude ash, 7 mm for length, 1.8 mm for width, 16.57 g weight/1000 grain, 2047 µg g-1 for total phenolic content, 12.54% for DPPH-2,2-diphenyl-1-picrylhydrazyl (DPPH) and 0.138% Copper reduction antioxidant capacity (CUPRAC) was higher compared to waxy non-pigmented rice but the 86.69% of starch and 11.7% of moisture content was lower compared to waxy non-pigmented rice. The results of total phenolic content and antioxidant activity is one way of utilizing the local drought resistant crops for nutritious and safe products in the promotion of food security in the country.
