【摘要】 以碎米淀粉为原料,己二酸为交联剂,通过单因素与正交实验确定己二酸交联碎米淀粉的最佳制备工艺。结果显示,制备己二酸交联碎米淀粉的最佳工艺条件为:己二酸的添加量为0.5%(m/m,相对于淀粉干基),pH值为9,反应时间为1.0 h,反应温度为60℃。在该条件下,制备的己二酸交联淀粉的交联度为0.75 mL。更多还原

【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.更多还原
