Abstract: To research the best grease extraction rate of yellow meal pupa, and provide biological property （density, acid value, etc.） for the grease of yellow meal pupa, we used yellow mealworm pupa and different proportional peanut combination as raw materials, and adopted the squeezing method to extract the grease. The optimal ratio of yellow meal pupa and peanut was 40% pupa, the grease yield efficiency was the highest. The higher the proportion of the pupa in the raw material, the higher the acid value. Grease density of each group is close to each other. The average saponification value of yellow meal worm pupa grease was 182.21.

Key words: yellow meal worm, squeezing method, grease yield efficiency, acid value
