Abstract:
Taking Zhongtian big hawthorn as test material,with nine treatements of the formula design was conducted in order to understand the preservation effect of using the chitosan complex film on the Hawthorn.The properties of Hawthorn after depoting in the 4 ℃,and relative humidity of 80%-90% conditions were tested in deferent time,which concluded decay rate,soluble solid content,vitamin C content,proanthocyanidin content,titratable acid content,free amino acid content and activity of polyphenol oxidase.The results showed that the properties of hawthorn fresh degree after depoting in the 4 ℃ were improved in the treatments of using the chitosan complex film than that not using.And the best preservation effect of the chitosan complex film the treatment which the formula design was 2% chitosan+1.5% CaCl2+1.0% glycerol.Therefore,chitosan complex film was conducive to the preservation of fresh hawthorn.
