摘要: 本文用不同绿色有机酸溶解壳聚糖(CTS)作为膜保鲜剂,从中筛选出对草莓保鲜效果较好的两类壳聚糖溶剂,分别是乳酸和柠檬酸。并进一步分别用微量元素Mn+与之复合,制备两大系列柠檬酸-CTS-Mn+和乳酸-CTS-Mn+复合物。通过对草莓涂膜保鲜及草莓各种营养成份的跟踪测定,及常温与冷藏条件的对比,筛选了对草莓适合的可食膜保鲜剂。

Abstract: In this paper, a series of film-protection reagents are prepared from dissolving CTS in different organic acids, fromwhich two CTS solvents with a good effect of freshkeeping for strawberries are selected. They are lactic acid and citric acid. Bothacids chelated with micro-element Mn+ and formed two series of complexes: Citric acid-CTS-Mn+ and Lactic acid-CTS-Mn+. Bymeans of tracing detection of freshkeeping effect and all nourishment ingredients in strawberries, meanwhile, by comparingkeeping conditions in normal and cold environments, an edible freshkeeping film of strawberry was sifted.
