Abstract
Abstract A process for producing an aqueous concentrate which can be pasteurized and subsequently reconstituted into a lump-free, thick soup, sauce, gravy or dessert, which process involves producing a concentrate in which are incorporated: (i) a proportion of starch sufficient to obtain a product of the desired degree of creaminess, (ii) a proportion of an appropriate osmotic-pressure increasing agent, sufficient to substantially reduce the rate of swelling of starch granules and prevent gelatinization of said starch during pasteurization, and (iii) a proportion of a water-activity depressing agent conducive to a water activity not exceeding 0.92.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A process for producing an ambient stable concentrate which on dilution with water or an aqueous liquid forms at a temperature from 65° to 100° C. into a lump-free, thick soup, sauce, gravy or dessert, which process comprises: (1) producing a concentrate containing: (a) water (b) starch, (c) a proportion of an appropriate osmotic-pressure increasing agent sufficient to substantially reduce the rate of swelling of the starch and prevent gelatinisation during a pasteurization treatment carried out at 60°-100° C., and (d) a proportion of a water-activity depressing agent conducive to a water activity not exceeding 0.92, (2) filling the concentrate into containers and sealing the containers, and (3) pasteurizing the concentrate in the sealed containers at 60°to 100° C.
Claim 2
Dependent Claim
119 words
A process for producing an ambient stable concentrate which on dilution with water or an aqueous liquid forms at a temperature from 65° to 100° C. into a lump-free, thick soup, sauce, gravy or dessert, which process comprises: (1) producing a concentrate containing: (a) water (b) starch, (c) a proportion of an appropriate osmotic-pressure increasing agent sufficient to substantially reduce the rate of swelling of the starch and prevent gelatinisation during a pasteurization treatment carried out at 60°-100° C., and (d) a proportion of a water-activity depressing agent conducive to a water activity not exceeding 0.92, (2) filling the concentrate into containers and sealing the containers, and (3) pasteurizing the concentrate in the sealed containers at 60°to 100° C.
Claim 3
Dependent Claim
22 words
A process according to claim 1, in which the osmotic-pressure increasing agent consists of a substance which does not penetrate starch granules.
Claim 4
Dependent Claim
33 words
A process according to claim 2, in which the osmotic-pressure increasing agent is selected from the group consisting of glucose syrup solids, maltodextrins having a DE-value ranging from 10-42, hydrolysed amylopectin and sucrose.
Claim 5
Dependent Claim
29 words
A process according to claim 1, in which the water-activity depressing agent is selected from the group consisting of physiologically acceptable salts, polyhydric alcohols, protein hydrolysates, lactose and glucose.
Claim 6
Dependent Claim
24 words
A process according to claim 1, in which the water activity of the composition is adjusted to a value ranging from 0.77 to 0.90.
Claim 7
Dependent Claim
27 words
A process according to claim 1, in which the concentrate contains 10 to 30 wt.% starch and has a moisture content ranging from 10 to 40 wt.%.
Claim 8
Dependent Claim
22 words
A process according to claim 1, wherein a concentrate is produced in which the proportions of starch:osmotic-pressure increasing agent:water correspond to 1:1-2:0.5-6.
Claim 9
Dependent Claim
65 words
A process according to claim 1, in which (a) a concentrate is produced which contains starch, a maltodextrin having a DE-value from 10-42 and water in proportions corresponding to 1:1-2:0.5-6, (b) the water activity of the concentrate is adjusted to a value not exceeding 0.92 by adding 0.1 to 7 wt.% of sodium chloride, and (c) the concentrate thus obtained is pasteurized at 60°-100° C.
