Abstract
Abstract The method for the processing of kriel to produce protein, lipids and chitin comprises emulsification of lipids by intensively stirring kriel in an aqueous medium. The resultant emulsion of lipids is separated from the kriel mass and from the kriel mass proteins are extracted at a pH of 10 to 12. The alkaline extract of proteins is separated from chitin integuments and protein is separated therefrom.
