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: 12
Claim 1
Independent Claim
35 words
A process for producing a gel food article comprising mixing a protein with an iridoid compound and allowing crosslinking of the protein at a pH which is higher than 4 but not higher than 10.
Claim 2
Dependent Claim
35 words
A process for producing a gel food article comprising mixing a protein with an iridoid compound and allowing crosslinking of the protein at a pH which is higher than 4 but not higher than 10.
Claim 3
Dependent Claim
12 words
A process according to claim 1 wherein said iridoid compound is genipen.
Claim 4
Dependent Claim
25 words
A process according to claim 2 wherein genipen is used in an amount ranging from 0.001 to 1 part per 1 part of the protein.
Claim 5
Dependent Claim
20 words
A process according to claim 2 wherein the crosslinking is effected at a temperature between 5° and l 100° C.
Claim 6
Dependent Claim
20 words
A process according to claim 3 wherein the gel food is in the form of a sheet, block or fiber.
Claim 7
Dependent Claim
57 words
A process for producing a gel food article comprising contacting a protein with an iridoid compound under heating and at a pH which is higher than 4 but not higher than 10 to cause gelation of the protein by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing heat denaturation of the protein.
Claim 8
Dependent Claim
57 words
A process for producing a gel food article comprising contacting a protein with an iridoid compound under heating and at a pH which is higher than 4 but not higher than 10 to cause gelation of the protein by crosslinking of primary amino groups thereof with the iridoid compound and simultaneously causing heat denaturation of the protein.
Claim 9
Dependent Claim
12 words
A process according to claim 6 wherein said iridoid compound is genipen.
Claim 10
Dependent Claim
25 words
A process according to claim 7 wherein genipen is used in an amount ranging from 0.001 to 1 part per 1 part of the protein.
Claim 11
Dependent Claim
20 words
A process according to claim 7 wherein the crosslinking and the heat denaturation is simultaneously effected at about 100° C.
Claim 12
Dependent Claim
20 words
A process according to claim 7 wherein the gel food is in the form of a sheet, block or fiber.
