Study on preparation and physicochemical properties of hexane diacid-crosslinked starch
Preparation methods and physicochemical properties of hexane diacid-crosslinked starch were investigated with orthogonal experiment.The results showed that resistant retrograding properties decreased,frost thawing stability increased,swelling degree decreased,and solubility decreased.The optimal condition was: pH 9.0,50 ℃,reaction time 1 h,concentration of hexane diacid 0.4%.
