摘要
通过乙醇溶剂法制备非晶颗粒态淀粉,再交联改性,制备非晶大颗粒交联淀粉,以交联度(溶胀法)为评价指标,采用正交试验设计优化条件,确定最佳工艺条件为:交联剂用量为淀粉干质量的1.5%、pH9.8、反应温度45℃、反应时间2 h;并对非晶交联淀粉的老化性、耐酸性、抗剪切性进行了研究。
Non-crystalline granular starch was prepared by ethanol solvent method and then modified by cross linking to prepare large non-crystalline and cross linked granular starch. Taking degree of cross linking （swelling method） as the evaluation indicator, the optimum technological conditions determined by orthogonal test were as following： dosage of cross linking agent was 1.5% of starch dry weight, pH 9.8, reaction temperature 45℃ and reaction time 2 tl. Meanwhile, the aging resistance, anti-acid and anti-shear properties of the non-crystalline and cross-linked granular starch were investigated.
