摘  要:
本文从海南特色海藻麒麟菜中提取多糖成分,将其作为荔枝涂膜保鲜剂的主要原料,以好果率、褐变指数、失重率、抗坏血酸含量作为指标,研究"2%麒麟菜多糖""2%麒麟菜多糖+2%VC"和"2%麒麟菜多糖+2%海藻酸钠"三种不同配方下麒麟菜多糖保鲜剂在常温下对荔枝的保鲜效果。结果表明,以麒麟菜多糖作为原料的涂膜保鲜剂一定程度上延长了荔枝的保鲜期,其中"2%麒麟菜多糖+2%VC"保鲜剂在抑制荔枝果皮褐变方面效果最好,而"2%麒麟菜多糖+2%海藻酸钠"保鲜剂对减少荔枝果肉水分蒸发效果最好。

摘  要:
The polysaccharide,which extracted from the Eucheuma,was made as the coating antistaling agent for litchi fruit.The good fruit rate,browning index,weight loss rate,and content of ascorbic acid were evaluated to study on the presevation effect of Eucheuma polysaccharide on litchi fruit at room temperature.The results showed that the Eucheuma polysaccharide could be used as coating antistaling agent to extend slightly shelf-life of litchi fruit.The 2% Eucheuma polysaccharide and 2% VC had better effect on inhibiting the browning of litchi pericarp,and the 2% Eucheuma polysaccharide and 2% alginate had the best effect on reducing water evaporation of litchi fruit.
