Abstract
Abstract Gel-like food article that has satisfactory functional characteristics such as high heat and acid resistance and yet which is safe to eat, and a process for producing this gel-like food article by crosslinking primary amino groups in food ingredients such as chitosan and proteins with an iridoid compound, which crosslinking may be combined with other methods of gelation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
53 words
A process for producing a gel food article comprising mixing a primary amino group containing compound with an iridoid compound, and allowing the crosslinking of the primary amino group containing compound with the iridoid compound to cause gelation wherein said primary amino group containing compound is chitosan and said iridoid compound is genipin.
Claim 2
Dependent Claim
53 words
A process for producing a gel food article comprising mixing a primary amino group containing compound with an iridoid compound, and allowing the crosslinking of the primary amino group containing compound with the iridoid compound to cause gelation wherein said primary amino group containing compound is chitosan and said iridoid compound is genipin.
Claim 3
Dependent Claim
58 words
A process for producing a gel food article comprising mixing a primary amino group containing compound with an iridoid compound, and allowing the crosslinking of the primary amino group containing compound with the iridoid compound to cause gelation wherein said primary amino group containing compound is a mixture of protein and chitosan and said iridoid compound is genipin.
Claim 4
Dependent Claim
58 words
A process for producing a gel food article comprising mixing a primary amino group containing compound with an iridoid compound, and allowing the crosslinking of the primary amino group containing compound with the iridoid compound to cause gelation wherein said primary amino group containing compound is a mixture of protein and chitosan and said iridoid compound is genipin.
Claim 5
Dependent Claim
68 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simulataneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer.
Claim 6
Dependent Claim
68 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simulataneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer.
Claim 7
Dependent Claim
12 words
A process according to claim 3 wherein said iridoid compound is genipin.
Claim 8
Dependent Claim
94 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer wherein said iridoid compound is genipin and said genipin is used in an amount ranging from 0.001 to 1 part per 1 part of said chitosan.
Claim 9
Dependent Claim
94 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer wherein said iridoid compound is genipin and said genipin is used in an amount ranging from 0.001 to 1 part per 1 part of said chitosan.
Claim 10
Dependent Claim
90 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer wherein said iridoid compound is genipin and said compound that is capable of being converted to a polyanionic polymer is polyphosphoric acid.
Claim 11
Dependent Claim
90 words
A process for producing a gel food article comprising contacting chitosan with an iridoid compound in the presence of a compound that is capable of being converted to a polyanionic polymer to cause gelation of the chitosan by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing gelation by the action of the compound that is capable of being converted to a polyanionic polymer wherein said iridoid compound is genipin and said compound that is capable of being converted to a polyanionic polymer is polyphosphoric acid.
Claim 12
Dependent Claim
20 words
