摘要
采用H2O2氧化降解法制备相对分子质量(Mw)为1500～2000的低分子质量壳聚糖。先用有益微生物制剂100液浸果2min,再用浓度为1.5%的低分子质量壳聚糖涂膜保鲜丰都红心柚。试验结果表明,在常温和普通民房贮藏条件下贮藏100天,其烂果率为9.2%、干疤率为10.3%,防腐保鲜效果优于化学防腐保鲜剂。
Low-molecutar weight chitosan with relative molecular of 1 500-2 000, is made by oxidation depolymerization. Pomelo are coated with with 1.5% ehitosan after dipped into 100 times solution of beneficial microorganism preparation, The results showed that after storage of 100 days, the rate of decay of fruits is about 9.2% and the rate of physiologleal dry scab 10,3%, and chemical preservative was excellent than biological flesh-keeping pagent.
