改性壳聚糖的研究及其在金秋梨保鲜中的应用
Study on Chitosan Modified and Its Application in Fresh-keeping of Jinqiu Pear
摘要
Abstract
As the chitosan was modified with nano-SiOx,nano-SiOx/chitosan composite film was obtained.Water/oxygen permeability and antibacterial activity Were in vestigated.Fresh-keeping ability of the chitosan films was evaluated by measuring contant of ascorbic acid,good fruits rate and storage life of Jinqiu pear at room temperature:The results showed:thewatt" permeability and oxygen permeability decreased by 35% and 21% respectively,and the composite film has obvious antibacterial activity,and the shelf life ofJinqiu pear was prolonged from 20 to 60 days,and the good fruits rate percent was 80% after 60 days.关键词
