Abstract
Abstract An edible plastic composition contains at least 5 wt.% of heat-denatured protein, the heat-denatured protein mainly being a dispersion in the form of non-aggregated protein-based macrocolloidal particles having a size in the range of from 0.1 to 10 microns. It is suitable as a low calorie fat replacer in food products and for topical applications and is prepared by successive heating and concentrating steps in which an aqueous composition comprising less than 15% by weight of the water, of heat-denaturable protein is at least partly denatured and the protein concentration of the aqueous composition is at least doubled and at least part of any soluble protein is removed. The present process for instance offers the advantage of not requiring complicated apparatus, and moreover is easy to control.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
85 words
Process for the preparation of a plastic food composition, the process comprising successively heating and concentrating an aqueous composition comprising less than 15% by weight of the water, of heat-denaturable protein so as to at least partly denature said protein and at least double the protein concentration of the aqeous denatured protein composition and remove at least part of any remaining undenatured protein present, to provide a plastic composition comprising at least 5 wt.% of heat-denatured protein in the form of non-aggregated protein-based microcolloidal particles
Claim 2
Dependent Claim
85 words
Process for the preparation of a plastic food composition, the process comprising successively heating and concentrating an aqueous composition comprising less than 15% by weight of the water, of heat-denaturable protein so as to at least partly denature said protein and at least double the protein concentration of the aqeous denatured protein composition and remove at least part of any remaining undenatured protein present, to provide a plastic composition comprising at least 5 wt.% of heat-denatured protein in the form of non-aggregated protein-based microcolloidal particles
Claim 3
Dependent Claim
23 words
Process according to any of the preceding claims wherein the concentration of protein in the aqueous composition is below the critical gel concentration.
Claim 4
Dependent Claim
23 words
Process according to claim 1 or 2 wherein the aqueous denatured protein composition is concentrated to a protein content of at least 7%.
