The physicochemical and pasting properties of amaranth starches isolated from five cultivars, Andy, Suvarna, Nu World, K266-1, K432, grown in Korea, were investigated. The shapes of starch granules were all polygonal and size was in the range 1.14~1.48 micro m for all five cultivars. X-ray diffractograms were shown typical A type diffraction patterns for all amaranth starches. The protein and crude lipid contents of starches were 0.13~0.23% and 0.01~0.05%, respectively. The apparent amylose contents ranged from 2.79~4.35% and the water binding capacities were 128.05~135.80%. The transmittances of 0.1% amaranth starch suspensions except K266-1 increased rapidly above 65 degrees, thereafter increased slowely.
