Research progress on new color retention technology for tilapia fillet

Good food color,not only can stimulate people’s appetite and desire to buy,but also improve the economic value of goods,so the color retention technologies for tilapia fillet were more and more popular in the processing of aquatic products at home and abroad.The objective of this paper was to introduce some color retention technologies for tilapia fillet.The mechanism and application of several color retention technologies for tilapia fillet were introduced,such as carbon monoxide(CO),nitric oxide(NO),nitrite and compound color retention technology for tilapia fillet.Finally,the prospects of color retention technologies for tilapia fillet were briefly discussed.This article is hoped to offer beneficial reference for the future application research and the wider application of color retention technologies for tilapia fillet in the processing of aquatic products.
