Abstract
Food products and pharmaceutical preparations containing one or more isoflavones are described. In particular, the invention relates to highly purified, crystalline isoflavones having an agreeable taste, texture and mouth-feel when formulated in food products and pharmaceutical preparations, and methods for the production of the highly purified, crystalline isoflavones.
Claims31
A method for the production of an alpha-crystalline form of isoflavones comprising the steps of:
- (a) extracting isoflavones from isoflavone-containing plant matter by contacting the isoflavone-containing plant matter with an aqueous organic solvent-mixture to give an extract solution;
- (b) filtering the extract solution to reduce the amount of plant matter having a molecular weight greater than that of the isoflavones;
- (c) reducing the solvent in the filtered solution to effect alpha-crystallisation of the isoflavones;
- and
- (d) recovering the alpha-crystalline isoflavones.

- (c) reducing the solvent in the filtered solution to effect alpha-crystallisation of the isoflavones;
- (d) recovering the alpha-crystalline isoflavones;
- (e) dissolving the recovered isoflavone crystals from step (d) in an organic solvent;
- (f) gradually reducing the volume of the organic solvent to effect the selective alpha-crystallisation of iso flavones;
- and
- (g) isolating the selective alpha-crystalline isoflavones.
The method of any preceding claim, wherein the selective alpha-crystalline isoflavones contain predominantly formononetin and daidzein.
The method of any preceding claim, wherein the selective alpha-crystalline isoflavones contain predominantly biochanin and genistein.
Alpha-crystalline isoflavones prepared by a method of any one of the preceding claims.
An alpha-crystalline form of isoflavones.
A food product or pharmaceutical preparation containing one or more highly purified isoflavones.
A method for the manufacture of a food product or pharmaceutical preparation including the step of bringing an alpha-crystalline form of isoflavones into admixture with one or more ingredients in said food product or pharmaceutical preparation, wherein the alpha-crystalline form is substantially colourless, odourless and virtually tasteless when formulated in said food product or pharmaceutical preparation.
An alpha-crystalline form of isoflavones, wherein the crystalline form has an X-ray powder diffractrogram with the following reflection signals (2 theta) of high and medium intensity
- 5 2 θ (2 theta) 7.0 9.9 15.8 22.7 23.0 23.9 26.3 26.9
