摘要
研究以小麦淀粉为原料采用酶解法制备脂肪模拟物,以葡萄糖当量(DE)为指标,考察小麦淀粉质量分数、酶添加量、酶解时间、酶解温度等因素对小麦淀粉脂肪模拟物制备的影响及制备脂肪模拟物的特性。在单因素试验基础上进行正交试验,得出最优工艺条件为小麦淀粉质量分数30%、酶添加量0.8 mg/g、酶解温度70℃、酶解时间12 min,在此工艺条件下小麦淀粉的DE值为6.20,其脂肪模拟物的持水性为53.30%。
The wheat starch was used as raw material to prepare fat mimetic by enzymatic hydrolysis.Taking dextrose equivalent(DE)as the indicator,the effects of starch mass concentration,enzyme content,enzymatic hydrolysis time and enzymatic hydrolysis temperature on the preparation and the characteristics of starch fat mimetic were investigated.Orthogonal experiments were carried out based on single factor tests,then the optimum process conditions were determined as follows:starch mass concentration 30%,enzyme content 0.8 mg/g,enzymatic hydrolysis temperature 70℃,enzymatic hydrolysis time 12 min.Under these conditions,the DE value of wheat starch was 6.20,the water holding capacity of wheat-starch-based fat mimetic was 53.30%.
