In order to study the Browning of fresh-cut lotus root,ascorbic acid(VC),calcium chloride and citric acid were selected as independent variables,and fresh-cut lotus root Browning degree(ΔE)was used as response value to protect the color of lotus root.The color protection effect of fresh-cut lotus root was studied with response surface optimization compound color protectants.The results showed that the optimal formula of compound color protection agent was citric acid 0.60%,calcium chloride 0.50%,ascorbic acid 0.70%,and the color protection effect was the best.This study could provide reference for inhibiting browning in the processing of fresh-cut lotus root.
