Earthworm meal
After drying, the worms were milled with hammer milling machine into a powder, packed as dried earthworm meal in airtight plastic bowls and stored at 0-20°C for further use (Sogbesan et al., 2007). Other drying methods include immersion in acetone (1 hour) followed by air- or oven drying (95°C), and freeze-drying.
