Study on Characteristics of Hot-air Drying of Tilapia and Its Main Components Changes
The characteristics of hot-air drying of fresh fish slices from tilapia at different temperatures(40~60℃) were investigated. At the same time, the contents of main components were assayed in this paper. Results showed that an increase in temperature results in an increase in drying rate.The total time of drying of fish slices needed to reach moisture equilibrium on higher temperature is at least 9 hours less than on lower temperatures. It also found that the drying rate changes significantly with differences in thickness of fish slices
