Abstract
The present invention provides isoflavone compositions exhibiting improved solubility (e.g., light transmittance), taste, color, and texture characteristics, and methods for making the same. The isoflavone compositions are useful for incorporation in a variety of foodstuffs, beverages, dietary supplements, and pharmaceutical compositions allowing for improved taste, texture, color, and optical properties of the same.
Claims16
A method of making a juice beverage, said method comprising
- a) combining a fruit juice with 0.15 to 3% by weight of polyvinyl pyrrolidone (PVP) or polyvinyl polypyrrolidone (PVPP) to form a precipitate containing polyphenolic compounds;
- b) removing said precipitate from said fruit juice;
- and
- c) adding at least 0.01% by weight of an isoflavone composition to said fruit juice to produce said beverage, said isoflavone composition comprising:
- i) two or more isoflavones, wherein said isoflavones represent about 15% to about 70% by weight of the composition;
- and
- ii) about 0.5% to about 30%, by weight, of a hydrophilic polymer, wherein said isoflavone composition, upon preparation of a mixture of about 0.03% by weight of the composition in water, exhibits a transmittance at 500 nm of at least 75%,
- wherein said beverage exhibits a transmittance at 600 nm that is increased at least 15% relative to the transmittance of a corresponding beverage prepared without removing said polyphenolic compounds.

A method of making a juice beverage, said method comprising
- a) combining a fruit juice with 0.15 to 3% by weight of PVP and at least 0.01% by weight of an isoflavone composition to form a precipitate containing polyphenolic compounds endogenous to said fruit juice, said isoflavone composition comprising:
- i) two or more isoflavones, wherein said isoflavones represent about 15% to about 70% by weight of the composition;
- and
- ii) about 0.5% to about 30%, by weight, of a hydrophilic polymer, wherein said isoflavone composition, upon preparation of a mixture of about 0.03% by weight of the composition in water, exhibits a transmittance at 500 nm of at least 75%;
- and
- b) removing said precipitate from said fruit juice to produce said fruit beverage, wherein said beverage exhibits a transmittance at 600 nm that is increased at least 15% relative to the transmittance of a corresponding beverage prepared without removing the polyphenolic compounds endogenous to said fruit juice.
