Abstract
The present invention relates to a process for removing fluorine from krill material by subjecting the krill to disintegration and to an enzymatic hydrolysis process prior to or simultaneously with a removal of the exoskeleton particles producing a fluorine-reduced product. The process of the invention can process krill material with a high polar lipid content for producing superior quality, low fluorine, products suitable for the food and feed as well as the pharmaceutical, nutraceutical and cosmetic industry.
Claims19
Process for removing fluorine from a catch of crustaceans, characterized in that the crustaceans, immediately after having been landed and at a temperature of around ambient temperature of the water, are disintegrated into smaller particles, and the disintegrated material is added to fresh water and heated to a temperature optimal for adding a proteolytic enzyme, or enzyme composition, and at which temperature the added enzyme(s) is/are allowed to work for no longer than 100 minutes, the hydrolysed material being fed to a separating device for separating solids from the processed material, and., through this removal of the solids fraction, reducing the fluorine content of the remaining proteinaceous material by at least 85% , the added (exogenous) and natural (endogenous) enzymes in the hydrolysing disintegrated proteinaceous material being deactivated before, during or after the removal of the solids fraction from the enzymatically processed material.
