Abstract
Abstract A high protein citrus food product is prepared which has good storage stability and texture by combining a major amount of citrus juice or the equivalent thereof with minor amounts of acid-soluble protein and solubilized starch. The starch is solubilized by heating in the presence of water and, optionally, an enzyme to effect partial hydrolyses. Additional food stabilizers can advantageously be added as well as sweeteners and flavoring components and the final mixture may be processed into a number of forms including dry power and concentrates.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
A stable, high protein citrus food product comprising at least about 50 percent by weight, based on the total weight of the composition, of full-strength citrus juice or the equivalent thereof in citrus solids, about 1-6 percent by weight of glycoprotein material soluble at a pH of about 2-4, about 0.1 -1.0 percent by weight of a soluble food stabilizer, about 0.5 -3.0 percent by weight starch which has first been solubilized and partially hydrolyzed by heating in water at a temperature of about 210* - 260* F. for about 10-15 minutes, and subsequently further hydrolyzed and solubilized by heating for an additional about 5-15 minutes at a temperature of up to about 140* F. in the presence of about 0.1 - 0.15 weight percent, based on the starch, of Alpha amylase enzyme, said enzyme then having been deactivated by raising the temperature above 140* F.
Claim 2
Dependent Claim
17 words
The citrus food product of claim 2 which contains about 2.0 -3.0 weight percent of said starch.
Claim 3
Dependent Claim
16 words
The citrus food product of claim 2 wherein said additional heating is for about 10-15 minutes.
Claim 4
Dependent Claim
46 words
The citrus food product of claim 1 wherein said citrus juice is orange juice and is present in amounts of about 85-92 weight percent of the full-strength 14* Brix juice or the equivalent thereof of orange juice solids, based on the weight of the food product.
Claim 5
Dependent Claim
47 words
The citrus food product of claim 1 wherein said citrus juice is a high acid citrus juice and is present in amounts of about 54-57 weight percent of 6*-14* Brix juice or the equivalent thereof of orange juice solids based on the weight of the food product.
Claim 6
Dependent Claim
27 words
The citrus food product of claim 1 wherein said food stabilizer is a low viscosity anionic polymer derived from cellulose which is tolerant of low pH systems.
