## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The process according to claim 1, wherein the ultrafiltration is performed by using high density ceramic membranes.

### Claim 3 (depends on 1)

The process according to claim 1, wherein the nanofiltration is performed by using highly selective membranes.

### Claim 4 (depends on 1)

The process according to claim 1, wherein the UF and NF water removal process can exploit excess energy on ships hereby reducing cost and increasing the ships operation duration and radius.

### Claim 5 (depends on 1)

The process according to claim 1, substantially reducing the need of water evaporation and energy.

### Claim 6 (depends on 1)

The process according to claim 1, wherein said ultrafiltration and nanofiltration can operate on stickwater and/or cooking water at temperatures of greater than 60° C.

### Claim 7 (depends on 1)

A hydrolysed marine protein product produced by the process according to claim 1, said hydrolysed marine protein product comprising hydrolysed marine proteins, peptides, peptones and a reduced level of monovalent ions and biogenic amines and water generated from enzymatic, cooking, acids and microbial degradation or any combination thereof.

### Claim 8 (depends on 7)

A feed product, comprising the hydrolysed marine protein product, comprising the hydrolysed marine protein product according to claim 7 and any carbohydrate source, vitamins, oils, fats and trace elements.

### Claim 9 (depends on 8)

The feed product according to claim 8, wherein the carbohydrate source is obtained from milk whey.

### Claim 10 (depends on 8)

The feed product according to claim 8, where need for a balanced diet for young pigs, dairy cattle, mink, fox, domestic pets and other species where fish protein is beneficial and high quality especially low monovalents and biogenic amines is needed, then the carbohydrate can be derived from by-products of milk processing.
