Abstract

Abstract A method for treating beverages containing turbidity procursors and/or enzymes is described. The technique involves contacting the beverages with a diol or dicarboxylic acid polycondensate at a temperature ranging from 28.4 DEG to 176 DEG F., thereby resulting in separation of deleterious substance. The colloidal and taste qualities of the resultant beverages is thereby enhanced.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 82 words
Method for stabilizing the colloidal and taste qualities of beverages evidencing turbidity precursors and enzymes which comprises the steps of: (a) contacting the beverage with an organic polymer selected from the group consisting of polyethylene terephthalate, isophthalic acid modified polyethylene terephthalate, and a mixture of polyethylene terephthalate and polybutylene terephthalate and at a temperature ranging from 28.4° to 176° F., in an amount sufficient to reduce the concentration of cloudiness precursors and undesirable enzymes and (b) separating the polymer from said beverage.
Claim 2
Dependent Claim 82 words
Method for stabilizing the colloidal and taste qualities of beverages evidencing turbidity precursors and enzymes which comprises the steps of: (a) contacting the beverage with an organic polymer selected from the group consisting of polyethylene terephthalate, isophthalic acid modified polyethylene terephthalate, and a mixture of polyethylene terephthalate and polybutylene terephthalate and at a temperature ranging from 28.4° to 176° F., in an amount sufficient to reduce the concentration of cloudiness precursors and undesirable enzymes and (b) separating the polymer from said beverage.
Claim 3
Dependent Claim 13 words
Method in accordance with claim 1 wherein the organic polymer is polyethylene terephthalate.
Claim 4
Dependent Claim 19 words
Method in accordance with claim 1 wherein the organic polymer is a mixture of polyethylene terephthalate and polybutylene terephthalate.
Claim 5
Dependent Claim 16 words
Method in accordance with claim 1 wherein the organic polymer is isophthalic acid modified polyethylene terephthalate.
Claim 6
Dependent Claim 18 words
Method in accordance with claim 1 wherein the organic polymer is dispersed in powder form in the beverage.
Claim 7
Dependent Claim 17 words
Method in accordance with claim 1 wherein the organic polymer is separated from the beverage by filtration.
Claim 8
Dependent Claim 17 words
Method in accordance with claim 1 wherein the organic polymer is separated from the beverage by sedimentation.
Claim 9
Dependent Claim 20 words
Method in accordance with claim 1 wherein the beverage is contacted with the organic polymer in a continuous throughflow plant.
Claim 10
Dependent Claim 21 words
Method in accordance with claim 1 wherein contacting is effected by flowing the beverage through a layer of pulverulent organic polymer.
Claim 11
Dependent Claim 21 words
Method in accordance with claim 1 wherein contacting is effected by flowing the beverage through a layer of fibrous organic polymer.
Claim 12
Dependent Claim 14 words
Method in accordance with claim 9 wherein the organic polymer includes a filtering material.
Claim 13
Dependent Claim 14 words
Method in accordance with claim 11 wherein the filtering material is an inorganic compound.
Claim 14
Dependent Claim 14 words
Method in accordance with claim 11 wherein the filtering material is an organic compound.
