摘　　要：随着科技的进步,膜包装技术在食品工业得到了飞速发展,但同时伴随“白色污染”问题。为了减少环境污染,选用了可再生的、可食用的高直链玉米淀粉为原料,主要研究了甘油用量、糊化方法、糊化时间、烘干温度以及羧甲基纤维素钠对成膜性质的影响。试验结果表明,高直链玉米淀粉可食性膜最佳成膜工艺参数为甘油用量1mL,羧甲基纤维素钠用量为0．1g,121℃糊化30min,干燥温度为90℃。With the development of science and technology, film packaging technique has gained great achievement in the field of food industry, together with the problem of ＂white pollution＂. In order to reduce environmental pollution, reproducible and edible high amylase of corn was used as material and the influence of glycerol, gelatinization methods, gelatinization time, drying temperature, and CMC - Na on the properties of film was studied. The results showed that the best parameter of film formation is when glycerol dosage is 1 ml, CMC -Na dosage is 0. 1g, gelatinization time is 30 min at 121℃, drying temperature is 90℃.
