The Preparation of Chitosan Complex and the Study of Keeping Strawberry Fresh

Abstract

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.

Key words: Chitoson complex, preparation, strawberry, fresh-keeping
