Study on the Prevetion of Browning of Freshly Cut Lotus Root with Compound Color Protecting Liquid
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.
