Abstract
Abstract A process for increasing the viscosity of cold milk under agitation is provided, which comprises of adding a blend of a phosphate such as sodium hexametaphosphate, sodium tripolyphosphate, or tetrasodiumpolyphosphate (TSPP) and a gum such as guar gum, carboxymethyl cellulose, or xanthan gum to milk. Preferably, approximately equal weights of the TSPP and xanthan gum are used, and about 0.05-1% of xanthan gum is in the final cold milk mix.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
The process for increasing the viscosity without solidification of a fluid milk mix at normal refrigeration temperatures under agitation which comprises adding to said milk mix a premixed blend, in either dry or aqueous concentrate form, consisting essentially of a gum and a phosphate wherein said gum is selected from the group consisting of xanthan gum, guar gum, and carboxymethyl cellulose and said phosphate is selected from the group consisting of sodium hexametaphosphate, sodium tripolyphosphate, and tetrasodiumpolyphosphate (TSPP), the blend of the two components being in approximately equal weight amounts; the amount of the pre-mixed blend added being such that from about 0.05% to about 1% gum (weight/volume) is in the milk mix.
Claim 2
Dependent Claim
113 words
The process for increasing the viscosity without solidification of a fluid milk mix at normal refrigeration temperatures under agitation which comprises adding to said milk mix a premixed blend, in either dry or aqueous concentrate form, consisting essentially of a gum and a phosphate wherein said gum is selected from the group consisting of xanthan gum, guar gum, and carboxymethyl cellulose and said phosphate is selected from the group consisting of sodium hexametaphosphate, sodium tripolyphosphate, and tetrasodiumpolyphosphate (TSPP), the blend of the two components being in approximately equal weight amounts; the amount of the pre-mixed blend added being such that from about 0.05% to about 1% gum (weight/volume) is in the milk mix.
Claim 3
Dependent Claim
11 words
The process of claim 1 wherein the gum is xanthan gum.
Claim 4
Dependent Claim
22 words
The process of claim 2 wherein the phosphate is TSPP and the level of gum is from about 0.09% to about 0.3%.
Claim 5
Dependent Claim
11 words

Claim 6
Dependent Claim
11 words
The process of claim 1 wherein the gum is carboxymethyl cellulose.
Claim 7
Dependent Claim
13 words
The process of claims 2, 4, or 5 wherein the phosphate is TSPP.
Claim 8
Dependent Claim
21 words
The process of claim 6 wherein the level of gum in the milk mix is from about 0.075% to about 0.68%
Claim 9
Dependent Claim
22 words
The process of claim 6 wherein the gum and TSPP is employed in ratios ranging from 40:60 parts to 60:40 parts, respectively.
