Title:
PROCESS FOR PRODUCING SOLUBLE ISOFLAVONE−CONTAINING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2003/000674
Kind Code:
A1
Abstract:
It is intended to provide a process for producing a soluble isoflavone−containing composition, which is in a natural state free from any solubilizers or chemical modification, has a high solubility under neutral to acidic conditions and shows a high long−time stability in a refrigerated state, starting with soybeans. From an aqueous soybean extract, insoluble matters are eliminated at pH 2 to 7 and at a temperature of 0 to 17°C. Thus, an isoflavone−containing composition excellent in solubility under neutral to acidic conditions and refrigeration stability can be obtained at a high efficiency.
