Abstract
Abstract The invention concerns gels and gelling systems of a polysaccharide and a chemically modified gelatin, preferably an acylated gelatin, whose isoelectric point is below the pH of the gel, e.g. below pH 4. Such systems overcome the problem of incompatibility between gelatin and polysaccharide at the low pH values commonly encountered in jelly desserts and confectionery due to the presence of fruit acids such as citric acid.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
40 words
An acidic dessert gel in which the gel-forming ingredients consist essentially of a polysaccharide gelling agent and a chemically modified gelatin gelling agent, the isoelectric point of said chemically modified gelatin gelling agent being below the pH of the gel.
Claim 2
Dependent Claim
40 words
An acidic dessert gel in which the gel-forming ingredients consist essentially of a polysaccharide gelling agent and a chemically modified gelatin gelling agent, the isoelectric point of said chemically modified gelatin gelling agent being below the pH of the gel.
Claim 3
Dependent Claim
10 words
A gel according to claim 1 containing a fruit acid.
Claim 4
Dependent Claim
9 words
A gel according to claim 1 containing citric acid.
Claim 5
Dependent Claim
17 words
A gel according to claim 1 wherein said chemically modified gelatin gelling agent is an acylated gelatin.
Claim 6
Dependent Claim
17 words
A gel according to claim 1 wherein said chemically modified gelatin gelling agent is a succinylated gelatin.
Claim 7
Dependent Claim
23 words
A gel according to claim 1 containing up to 40 wt. %, based on said chemically modified gelatin gelling agent, of non-gelling extender.
Claim 8
Dependent Claim
27 words
A gel according to claim 6 containing about 20 wt. % of said polysaccharide gelling agent, based on the total weight of said gelling agents plus extender.
Claim 9
Dependent Claim
54 words
A gelable mixture suitable for forming an acidic dessert gel in which the gel-forming ingredients consist essentially of a polysaccharide gelling agent and a gelatin gelling agent in which the amino groups of said gelatin have been modified by chemical reaction to reduce its isoelectric point and an effective amount of a fruit acid.
Claim 10
Dependent Claim
54 words
A gelable mixture suitable for forming an acidic dessert gel in which the gel-forming ingredients consist essentially of a polysaccharide gelling agent and a gelatin gelling agent in which the amino groups of said gelatin have been modified by chemical reaction to reduce its isoelectric point and an effective amount of a fruit acid.
Claim 11
Dependent Claim
16 words
A mixture according to claim 8 in which said gelatin gelling agent is an acylated gelatin.
Claim 12
Dependent Claim
22 words
A mixture according to claim 8 wherein said gelatin gelling agent has its isoelectric point at a pH of 4 or less.
Claim 13
Dependent Claim
12 words
A mixture according to claim 9 containing a polybasic organic fruit acid.
Claim 14
Dependent Claim
10 words
A mixture according to claim 8 containing a non-gelling extender.
Claim 15
Dependent Claim
22 words
A mixture according to claim 12 in which said extender is selected from the group consisting of starch hydrolysate and protein hydrolysate.
Claim 16
Dependent Claim
26 words
A mixture according to claim 9 wherein the polysaccharide gelling agent is selected from the group consisting of carragheenins, furcellarans, Danish agar, alginate esters, and pectins.
Claim 17
Dependent Claim
40 words
A method of forming an acidic dessert gel which comprises forming an aqueous gelling composition comprising water and a mixture according to claim 8 mixed in proportions effective to form a gel and allowing or causing the composition to gel.
