Abstract
Abstract A protein food product comprises a protein ingredient, particularly fish, and a water-soluble cellulose ether intimately associated with a gel matrix of a polyvalent metal salt of alginic acid. Such a product can be made by forming a mixture of the protein and cellulose ingredients together with a matrix precursor and sufficient water to form a sol which is subsequently set to a gel with the appropriate matrix setting agent.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
A PROTEIN-CONTAINING FOOD PRODUCT SUITABLE FOR USE AS AN INGREDIENT IN SAVOURY OR UNSWEETENED FOODSTUFFS, WHICH FOOD PRODUCT IS IN THE FORM OF A THERMOSTABLE GEL AND CONSISTS ESSENTIALLY OF: A. ABOUT 0.3 TO 3.0% BY WEIGHT OF A CELLULOSE ETHER SELECTED FROM EDIBLE WATER-SOLUBLE ALKYL, HYDROXYALKYL AND CARBOXYALKYL CELLULOSES THE ALKYL RADICALS OF WHICH CONTAIN FROM 1 TO 3 CARBON ATOMS, B. ABOUT 0.2 TO 5.0% BY WEIGHT OF A CALCIUM SALT OF AN EDIBLE ALIGNIC ACID, AND C. THE BALANCE COMPRISING WATER AND AN EDIBLE PROTEIN INGREDIENT SELECTED FROM THE GROUP CONSISTING OF FINELY DIVIDED OR CHEMICALLY CONCENTRATED FISH, MEANS, POULTRY AND VEGETABLE PROTEIN.

Claim 3
Dependent Claim
23 words
A protein-containing food product according to claim 1, wherein said cellulose ether comprises from 0.5 to 1.5% by weight of said food product.
Claim 4
Dependent Claim
25 words
A protein-containing food product according to claim 2, wherein said cellulose ether is selected from sodium carboxymethyl cellulose, methyl cellulose, ethyl cellulose and hydroxypropyl cellulose.
Claim 5
Dependent Claim
