ABSTRACT
The study was designed to determine selected components of chemical composition in the body of earthworms cultivated on organic kitchen waste. It was shown that their biomass can be classified as protein-rich, succulent fodder. Notably, this work also specified the contents of 17 essential amino acids, as well as the profile of fatty acids. It also highlighted selected threats to the natural environment caused by food production and food wastage by man. Because of that, this paper also presents the determinants of earthworm biomass production. The possibilities of consuming alternative invertebrate protein were also discussed.
