摘要: 本文采用含硫化合物L-半胱氨酸、酸化剂苯甲酸、酶底物竞争性抑制剂肉桂酸、防腐剂山梨酸;螯合剂β-环糊精等褐变抑制剂对鲜切马铃薯褐变的抑制效果进行了研究。通过褐变度与多酚氧化酶活性相关分析和比较确定了不同抗褐变剂实际效果。结果表明,L-半胱氨酸、肉桂酸、苯甲酸对鲜切马铃薯具有良好的抗褐变效果。

Abstract: The fresh-cut potato anti-browning effects has been studied. The selected anti-browning agents: ascorbic acid, L- cysteine, sorbic acid, benzoic acid, cinnamic acid and β-cyclodextrin was treatmented with fresh-cut potato. The relative effectiveness of these anti-browning agents for inhibition of enzymic browning in sliced potatoes was determined in terms of colour and enzyme activity measurements. The most effective agents were determined as L-cysteine, cinnamic acid and benzoic acid.

Key words: fresh-cut potato, browning, polyphenoloxidase
