Abstract
Abstract A foodstuff in the form of a thermostable gel containing a characterising protein ingredient, particularly a fish protein, is obtained by admixing at a pH above 7 the protein ingredient and a propylene glycol ester of alginic acid so that a waterinsoluble protein-alginate polymer is formed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A PROCESS FOR THE PREPARATION OF A PROTEIN-CONTAINING FOODSTUFF IN THE FORM OF A THERMOSTABLE GEL, COMPRISING THE STEPS OF: A. ADMIXING AN EDIBLE PROTEIN INGREDIENT AND A PROPYLENE GLYCOL ESTER OF ALGINIC ACID AT A PH ABOVE 7, SAID PROPYLENE GLYCOL ESTER BEING SUCH THAT AT LEAST 50 PERCENT OF THE CARBOXYL GROUPS OF THE ALGINIC ACID ARE ESTERIFIED, B. ASSISTING THE SETTING OF THE MIXTURE OF SAID PROTEIN INGREDIENT AND SAID PROPYLENE GLYCOL ESTER BY EXTRUSION OF SAID MIXTURE INTO AN AQUEOUS SOLUTION OF AN ALKALI SELECTED FROM THE GROUP CONSISTING OF SODIUM CARBONATE AND SODIUM HYDROXIDE AND MIXTURES THEREOF, AND C. ADJUSTING IF NECESSARY TO A VALUE IN THE RANGE OF 5 TO 8 TO PH OF THE THERMOSTABLE GEL SO FORMED, BY WASHING SAID GEL WITH A DILUTE AQUEOUS SOLUTION OF AN ACID SELECTED FROM THE GROUP CONSISTING OF ACETIC ACID AND HYDROCHLORIC ACID, EXTRANEOUS FLUID BEING REMOVED BY CENTRIFUGING.

Claim 3
Dependent Claim
13 words
A process according to claim 1, wherein said protein ingredient is fish protein.
Claim 4
Dependent Claim
15 words
A process according to claim 2, wherein said fish protein is a substantially denatured material.
Claim 5
Dependent Claim
15 words
A process according to claim 3, wherein said fish protein is a fish protein concentrate.
Claim 6
Dependent Claim
43 words
A process according to claim 4, wherein said mixture consists essentially of, by weight, from 17 to 25 percent of said fish protein concentrate and from 0.6 to 2.0 percent of said propylene glycol ester, the balance of said mixture being predominately water.
