The coatings are a safe， non-toxic and effective way of food processing， its application in food preservation has been relatively mature. In recent years， edible coatings increase gradually in the application of deep-fat fried foods because of the efficient way of blocking oil absorption and moisture to offshoring， so it has a unique advantage in water retention and reducing oil absorption. Compared with polysaccharides and plant protein coatings， animal proteins have the advantages of avoiding allergies， high nutritional value， good mechanical properties and increasing the added value of by-products， and have shown a tendency to replace the formers. In this paper， the application of edible animal protein coatings to inhibit oil absorption in deep fried foods was introduced， and the mechanism of inhibiting oil absorption was described in detail.
