摘要
明胶是一种生物高聚物,常以甘油为增塑剂,被广泛用于制备膜材料。本文考察了甘油浓度对不同道次明胶水溶液的性能影响。在明胶用量一定时,设置甘油与明胶不同配比探讨甘油对不同道次明胶溶液性能的影响。研究结果表明:随着甘油加入量的增加,各道次明胶溶液的凝冻强度变化不明显,而勃氏粘度增大较显著。因此,在保证明胶凝冻强度一定的情况下,甘油可以作为明胶材料的增塑剂。
Gelatin as a biopolymer, which often uses glycerol as a plasticizer, is widely used in the preparation of film material. In this work, the effect of glycerol concentration on gelatin solution properties from different extractions is in- vestigated. The results showed that： with the increasing of glycerol, the gel strength of gelatin solution from different extractions had little change while viscosity significantly increased. Therefore, glycerin can be used as a plasticizer in gelatin material.
