Abstract
A hydrolyzed marine protein product, a method for the production of the product, a feed product for animals, including humans, and a culture medium including the hydrolyzed marine protein product. The protein product may be hydrolyzed by enzymatic activity, bacterial activity, acids, cooking or any combination of these. The protein product may also include stickwater peptide fraction containing bioactive peptides. Feed product could be any nutritional product comsumable by any animal including humans.
Claims10
A process for the production of a hydrolysed marine protein product, comprising the following steps:
- a) homogenizing by-product from fish and/or other marine sources;
- b) controlled hydrolyses of the proteins contained within said sources and/or separation of stickwater from processing of marine raw material;
- c) subjecting the hydrolysate from step b) to ultrafiltration producing a UF permeate containing hydrolysed proteins and a UF retentate containing oil fibres, fat emulsions and other large molecules;
- d) the UF permeate from step c) is further subjected to nanofiltration, producing a NF permeate containing water, monovalent ions and biogenic amines and a NF retentate containing hydrolysed proteins;
- e) the UF retentate from step c) and NF retentate from step d) are concentrated separately or in combination dried by spray, vacuum or any other drying method;
- and
- f) the NF permeate containing water, monovalent ions and biogenic amines are discarded.
