Abstract
Abstract The invention relates to a method for the processing, sterilization and packaging of a food product starting from a raw material basically consisting of Krill, in order to obtain a protein rich food product with good taste, consistency, structure, preparing abilities and keeping properties. Said method includes the steps of breaking down the whole Krill into small particles, sterilization of the broken down Krill, cooling and grinding the sterilized product into liquid or semi-liquid form and packaging the liquid substance under aseptic conditions, whereby the liquid substance is solidified in the aseptic packages.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
A method for treating and packaging a food product containing proteins comprising: (a) providing a raw product containing proteins; (b) reducing the raw product to a plurality of particles having a size smaller than 5 mm. to change the raw product to a homogenous fluid or semifluid form; (c) sterilizing the raw product thereby at least partly causing the proteins to coagulate; (d) cooling the at least partly coagulated sterilized raw product to below the coagulating temperature; (e) homogenizing the cooled product to fluid or semifluid form; and (f) packing the sterilized, homogenized product under aseptic conditions into bacteriaproof packages and allowing the packed product to thicken to solid or semisolid form.
Claim 2
Independent Claim
112 words
A method for treating and packaging a food product containing proteins comprising: (a) providing a raw product containing proteins; (b) reducing the raw product to a plurality of particles having a size smaller than 5 mm. to change the raw product to a homogenous fluid or semifluid form; (c) sterilizing the raw product thereby at least partly causing the proteins to coagulate; (d) cooling the at least partly coagulated sterilized raw product to below the coagulating temperature; (e) homogenizing the cooled product to fluid or semifluid form; and (f) packing the sterilized, homogenized product under aseptic conditions into bacteriaproof packages and allowing the packed product to thicken to solid or semisolid form.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the sterilizing step is performed at a temperature of at least 120° C. for at least 4-8 seconds.
Claim 4
Dependent Claim
25 words
The method of claim 1 wherein the reduced raw product is subjected to the action of a pH adjusting substance prior to the sterilization step.
Claim 5
Dependent Claim
29 words
The method of claim 1 wherein a thickening substance selected from the group consisting of coagulating agents and water-absorbing organic compounds is added to the raw product before packing.
Claim 6
Dependent Claim
11 words
The method of claim 4 wherein the thickening substance is rice.
Claim 7
Dependent Claim
35 words
The method of claim 1 wherein the raw product is selected from the group consisting of Krill, whole prawns or parts thereof, whole shrimp or parts thereof, cleaned fish, uncleaned fish, and fish cleaning waste.
Claim 8
Dependent Claim
29 words
The method of claim 6 wherein the packed product includes larger pieces of material selected from the group consisting of protein-rich material, carbohydrate-rich material and protein and carbohydrate-rich material.
Claim 9
Dependent Claim
21 words
The method of claim 1 wherein the reduction of the raw product is at least in part caused by biochemical action.
Claim 10
Dependent Claim
15 words
The method of claim 1 wherein the raw product is reduced to colloidal particle sizes.
Claim 11
Dependent Claim
16 words
The method of claim 1 wherein the sterilizing step is performed prior to the reducing step.
Claim 12
Dependent Claim
14 words
The method of claim 1 wherein the reducing and sterilizing steps are performed concurrently.
Claim 13
Dependent Claim
18 words
The packed product prepared in accordance with the method of claim 6 wherein the raw product is Krill.
