摘要: 文研究了不同褐变抑制剂对鲜切苹果PPO活性、褐变度、感官品质的影响。试验结果表明:单一的1.5%L-半胱氨酸、1.0%D-异VC钠、1.0%谷胱甘肽处理均能较好地抑制鲜切苹果褐变。采用0.10%D-异VC钠+0.12%谷胱甘肽+0.13%L-半胱氨酸,浸泡2min的复合处理,可使鲜切苹果的PPO活性、褐变度、感官品质在14d内保持较优水平。

Abstract: The effects of different inhibitors on PPO activity,browning degree and quality of appearance of fresh-cut apples were studied.The results showed that the effects of 1.5% Cys,1.0% sodium D-isoascorbate,and 1.0% GSH on browning inhibition of fresh-cut apples during storage period are optimum among the single browning inhibitors.The optimum combination treatment is 0.10% sodium D-isoascorbate+0.12% GSH+0.13% Cys,and the optimum time for the fresh-cut apple slices dipping in the solution is 2min,which can keep the PPO activity,the browning degree and the quality of appearance in super level within 14d.
