Abstract: The traditional processing technology of fried grass carp was improved by vacuum-frying technology. The sizes of the surface pore of the products by two different processing technologies were compared. And the moisture absorption properties of the product were studied. The results showed that the optimal conditions of vacuum-frying technology are vacuum degree 0.06 MPa, temperature 130 ℃ and frying time 13min. The size of surface pore of the vacuum-fried product is obviously larger than the traditional product and the color of the traditional product is obviously darker than that of the vacuum- fried one.

Key words: grass carp, vacuum-frying, moisture absorption isotherm, surface pore, color difference
