摘要: 用单因素试验和正交试验法探讨了西瓜保鲜剂的主要成分苯甲酸钠(A)、山梨酸钾(B)、亚硫酸氢钠(C)等对保鲜西瓜所起作用的大小及最佳浓度,并就西瓜保鲜剂对西瓜的耐寒及耐热性的影响进行了探讨。结果表明,苯甲酸钠、山梨酸钾单独使用的最适浓度为1800mg·L-1和1500mg·L-1,可使贮存30d(天)的西瓜的好果率由38.1%提高到62.1%和65%。亚硫酸氢钠单独试用于西瓜保鲜有一定的副作用。多因素正交试验结果表明,影响西瓜保鲜的因素的主次顺序为:B>C>A。其最佳组合为A2B2C2,即苯甲酸钠(800mg·L-1)、山梨酸钾(800mg·L-1)、亚硫酸氢钠(400mg·L-1)。经保鲜剂处理过的西瓜,在1~10℃下贮藏45d(天)未见冷害,在28~38℃下贮藏45d(天),其失水率均小于9.5%,而未处理的则高达18%。

Abstract: The effect and their optimal concentration of sodium b e nzoate (A),potassium sorbate (B),sodium sulfite (C) on the storage of watermel on were studied by single factor experiments and cross experiments. And the cha r acteristics of antifreezing,anti-high-temperature of watermelon preservative were discussed. The results indicated that the optimal concentrations of sodium b enzoate,potassium sorbate were 1800mg·L-1 and 15 00mg·L-1 respectively,which increased the rate of non-decayed w atermelon that store...
