The Potential Use of Raw and Deodorized Non-Conventional Protein Powder in Human Food

This study aimed to evaluate the potential use of a non-conventional protein source, a powder made from earthworms, as human food. Sensory analyses were done in order to assess the acceptability of cookies that were fortified with Eisenia foetida (Ef) protein powder. Cocoa and cinnamon were used as taste-masking agents. The acceptability of cookies fortified with deodorized Ef protein powder (off-flavor reduced) was also evaluated. We demonstrated that cocoa cookies can be fortified with 3.9% of raw Ef proteins and that cocoa/cinnamon cookies can be fortified with 5.2% of raw Ef proteins without any loss in their acceptability. Cookies fortified either with a raw protein powder or with a de…
