Objective: To optimize extraction technology of earthworm protein by wet ultrafine grinding technology. Method: On the basis of single-factor test
extraction technology of wet ultrafine grinding method on earthworm protein was optimized with soaking time
solid-liquid ratio
extraction temperature and grinding time as influencing factors
yield of protein as response value.According to central composite test design principles
4 factors and 3 levels of response surface analysis method was used. Result: Optimum extraction process of earthworm protein by wet ultrafine grinding technology was as follows:soaked 4.7 h
solid-liquid rate 1∶11
extraction temperature 17 ℃
grinding time 10 min. Under these conditions
yield of protein could be up to 3.46%. Conclusion: Wet ultrafine grinding technology was suitable for extraction of earthworm protein.This optimize extraction technology was stable
