COATING AGENT COMPOSITION CONTAINING CHITOSAN IMPROVED IN ADHESIVENESS FRUIT SURFACE COMPRISING WAX LAYER AND SELF-DIGESTION INHIBITING PROPERTY AND PRODUCTION THEREOF

摘要

PURPOSE: A method of preparing a chitosan-containing coating agent composition capable of reducing breathability of fruits and inhibiting the self-digestion thereof and decomposition of nutrients thereof such as acid, sugar, etc. during storage by being evenly coated on the fruit surface during soaking and drying is provided. Therefore, the composition can remarkably enhance storability of fruits. CONSTITUTION: In the process of producing the coating agent composition, chitosan is added to deionized water and thereafter agitated with a homogenizer to give a colloidal homogeneous mixture. Then, the mixture is added with lactic acid or acetic acid to thoroughly dissolve chitosan and then with tween 80. The coating agent composition containing chitosan comprises: 0.1 to 10% by weight of chitosan, 0.5 to 5% by weight of lactic acid or acetic acid; 0.5 to 5% by weight of glycerine; 0.01 to 5% by weight of tween; and 75 to 98.89% by weight of deionized water.
