Abstract:The preparation of hexane diacid-crosslinked broken rice starch was studied using broken rice starch as raw materials using hexane diacid as crosslinking regents. Single factor test and the following orthogonal experimental design were used to obtain the best preparation technology. The amount of hexane-diacid, pH, reaction time and reaction temperature were 0.5% (m/m), 9, 1.0 h and 60 ℃, respectively. Under these conditions, the preparation of hexane diacid-crosslinked starch’s crosslinking degree is up to 0.75 mL.
