摘要
以壳聚糖为涂膜基质,以甘油为成膜助剂,配制成多糖涂膜保鲜剂,研究了温度28～32℃,相对湿度68%～86%下该多糖涂膜保鲜剂对山楂品质的影响。结果表明,常温下经壳聚糖涂膜保鲜剂涂膜保鲜的山楂与对照组相比,果实的霉烂率、失重率明显降低,VC转化、流失的速度减慢,延缓了果实的衰老,从而延长了其常温贮藏期。
In this study,the preservation effects of compound coating antistaling agent of polysaccharide on Crataegus pinnatifida with temperature 28-32℃ and relative humidity 68%~86% were investigated.The antistaling agent was composed of chitosan for the coating matrix,and glycerin as film-forming additives.The results showed that compared with the control group ,the rotten fruit rate and weightloss rates of the Crataegus pinnatifida preserved by the compound coating antistaling agent of edible polysaceharide were lower, the conversion of content of total Vc was inhibited, and the senescence process was restrained, the storage and the shelf life was extended.
