Enzymatic Browning Controling of Fresh Cut-lotus Roots

The high inhibitors including Citric acid(CA),Sodium D-isoascorbate(D-EA) and Edathamil disodium(EDTA-2Na) of activity of polyphenol oxidase of lotus root Neulmbo nucifera Gaerth were used as the enzymatic browning inhibitors of fresh-cut lotus roots.The effects of the inhibitors and its combination on the inhibition of enzymatic browning of fresh cut lotus root were studied.The results showed that the optimal dosage of combination of this three enzymatic browning inhibitors was 2.5 g/L CA+1.5 g/L D-EA+1.5 g/L EDTA-2Na.
