Effects of Extraction Concentration of Alkali on Physicochemical Properties of Red Kidney Bean Starch
摘要
Abstract
Red kidney bean starch was isolated by dry grinding and alkali extraction processing method,and the effects of different extraction concentration of alkali on physicochemical properties of red kidney bean starch from Suihua area of Heilongjiang province was studied. The results showed that the optimum extraction factor was as follows:concentration of alkali 0.20%,extraction yield 24.59%,moisture content 12.62%,protein residues 0.14%,fat content 0.15% ,ash content 0.16%,light transmission rate 5.6%, under the 90℃,the solubility and degree of swelling were 8.94%and 20.27 g·g-1,respectively. The syneresis rate was 36.11%after 5 freeze-thaw cycle,and the water adsorption rate displayed the tendency of increasing slowly before rapidly rising.关键词
