Abstract:
In this study, the preservation effects of a compound coating of polysaccharide on Prunus avium L. at room temperature (25~28 ℃) and relative humidity (68~75%) were investigated. The antistaling agent was made using Sophoraalopecuroides bean galactomannan as the coating matrix. CaCl2 and citric acid were used as film-forming additives and glycerin was added to improve the film flexibility. The results showed that the use of the compound coating obviously lowered the rotten rate, cracking fruit rate and weightloss rates of Prunus avium L. preserved, inhibited the respiration rate and the loss of total Vc and organic acids and other nutrients. The contents of MDA and anthocyanin, as well as the relative conductivity, were effectively increased, thus resulting in lower PPO and POD enzyme activities. Use of the compound coating of Sophoraalopecuroides bean galactomannan may delay the senescence process during storage and extending the shelf life.
