Abstract
Abstract Debranched amylopectin and debranched low-DE maltodextrin have been found to cause protein to aggregate in solution. Such aggregation, which can lead to precipitation or flocculation of the protein, is useful for instance in aerated aqueous fat emulsions, e.g. ice cream and whipped cream, where the stability of the product can be altered as desired.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
39 words
A process for aggregating protein which comprises preparing an aqueous solution of a protein, adding thereto a polysaccharide aggregating agent selected from the group consisting of debranched amylopectin and debranched low D.E. maltodextrin, and allowing the protein to aggregate.
Claim 2
Dependent Claim
39 words
A process for aggregating protein which comprises preparing an aqueous solution of a protein, adding thereto a polysaccharide aggregating agent selected from the group consisting of debranched amylopectin and debranched low D.E. maltodextrin, and allowing the protein to aggregate.
Claim 3
Dependent Claim
18 words
The process according to claim 1 wherein an aqueous solution of approximately 0.5 to 1% protein is prepared.
Claim 4
Dependent Claim
31 words
The process according to claim 1 wherein the aggregating agent is added to the protein solution in the form of an aqueous solution in the range 0.05 to 1% aggregating agent.
Claim 5
Dependent Claim
34 words
The process according to claim 1 wherein the aggregating agent is debranched by preparing an aqueous solution of the agent and adding thereto an α-1,6-glucosidase in a system free of enzymes having hydrolytic activity.
Claim 6
Dependent Claim
18 words
The process according to claim 4 wherein the α-1,6-glucosidase is produced by culturing the microorganism Cytophaga NCIB 9497.
Claim 7
Dependent Claim
23 words
The process according to claim 1 wherein the polysaccharide aggregating agent contains by weight at least 2% linear polyglucosides containing 30-55 glucose units.
Claim 8
Dependent Claim
22 words
The process according to claim 1 wherein the aggregating agent contains by weight at least 10% linear polyglucosides containing 30-55 glucose units.
Claim 9
Dependent Claim
50 words
A process for preparing a stable aqueous fat emulsion which comprises (a) preparing an emulsion comprising a fat and an aqueous phase containing protein and an aggregating agent selected from the group consisting of debranched amylopectin and debranched low D.E. maltodextrin, and (b) dispersing a non-reactive gas throughout the emulsion.
Claim 10
Dependent Claim
50 words
A process for preparing a stable aqueous fat emulsion which comprises (a) preparing an emulsion comprising a fat and an aqueous phase containing protein and an aggregating agent selected from the group consisting of debranched amylopectin and debranched low D.E. maltodextrin, and (b) dispersing a non-reactive gas throughout the emulsion.
Claim 11
Dependent Claim
26 words
A process according to claim 8 wherein, after the gas is dispersed throughout the aqueous fat emulsion, the emulsion is cooled to form an ice confection.
