摘要
Abstract
With corn starch as experimental material,glycerol as plasticizer,sodium carboxy methyl cellulose and sodium alginate composite for strengthening agent,using delay flow for corn starch composite membrane. Both plasticizer and reinforcing agent's types, usages, drying temperature, flow volume etc to the effectiveness of composite membrane's capability were studied.Pullulanase was used to cleave the branching point of amylopectin for preparing starch film.Using the orthogonal trials and measuring tensile strength with corn starch composite film, it was found that the best condition for pullulanase to degrease corn starch was that pullulanase 0.8ASPU/g, pH4.5 ,time 4h,temperature 60℃.关键词
