摘要
Abstract
A novel hydrogel composite film was fabricated with carboxymethyl chitosan(CMCS)and carboxymethyl cellulose(CMC-CHO)as raw materials.The CMCS/CMC-CHO film showed good tensile property,moisture permeability,transparency,and excellent UV absorption ability.In addition,the inhibitory effect of CMCS/CMC-CHO on Aspergillus nige and Penicillium expansum were superior to that of CMCS.The application results on strawberry preservation showed that the effect of CMCS/CMC-CHO coating solution was better than that of CMCS and CMCS/CMC-CHO/Gly.After 7 days of storage,the decay rate and weight loss rate of strawberry were reduced by 41.94％and 10.64％respectively,and the hardness,organic acid content,soluble solid content,reducing sugar content and Vc content compared with the control were increased by 35.11％,36.67％,14.13％,3.51％and 44.30％,respectively.关键词
