Effect of papaya and corn silk extracts on color and quality of mushroom (Agaricus bisporus) slices during blanching

摘要: 采用烫漂前浸泡和烫漂时添加两种方式,研究了木瓜和玉米须提取物对双孢菇片烫漂后颜色和品质的影响。结果表明,两种植物提取物的不同添加方式均可以在一定程度上抑制菇片的褐变和保持菇片的品质,其中浸泡前处理效果较好。木瓜和玉米须提取物最佳浸泡浓度均为2.0g/L,最大褐变抑制率分别为16.89%±4.57%、10.02%±3.24%;与清水浸泡前处理相比,维生素C含量分别提高67.30%、21.78%,总酚含量分别提高17.34%、38.29%。

Abstract: The impact of papaya and corn silk extracts on color and quality of mushroom (Agaricus bisporus) slices during blanching were investigated.Compared with the contrast group, two different extracts addition way (soaking and blanching) could inhibit browning and keep quality of the mushroom slices in a degree, but the better way was soaking treatment.The results showed that the optimum soaking concentration of papaya and corn silk extracts were 2.0g/L, and the maximum browning inhibition rate were 16.89%±4.57% and 10.02%±3.24% respectively.Compared to the water treatment, the vitamin C content of mushroom slices increased by 67.30% and 21.78%, and total phenolic content enhanced by 17.34% and 38.29%, separately.
