Soybean extract soy isoflavone is made from the seeds of Glycine max (Linn.) Merr .The rich isotope in soybeans is a natural phytoestrogens, which reduces the incidence of teenage breast cancer, relieves menopausal symptoms, and increases bone density. Therefore, soybean isoflavone research is hot recent years.
There are a total of 12 types of soy isoflavone naturally exist in soybeans, which can be divided into 3 categories, namely, Daidzin , Genistin, and Glycitin. Each type exists in four forms: free type, glucoside type, acetyl glucoside type, and malonyl glucoside type.
Glycine max (Linn.) Merr.
10%,20%, 40% Isoflavone
How to extract ：
Soybean meal (around 0.11% of total isoflavones) is refluxed with 70% ethanol. The extract is compressed to recover the ethanol until it is exhausted. The thick wall liquid is appropriately diluted and separated by a tubular separator. The centrifuged liquid flow through macroporous absorbent resin collumn. Rinse with pure water until the elute is clear and colorless, and then eluted with 80% ethanol, collect the eluate, and recover the ethanol . The concentrated filterate is purified and vacuum dryed the Soybean extract soy isoflavonepowder is obtained.
How to identify soybean isoflavone source
Here is the comparison of germ extraction and soybean meal extraction and content analysis of added ingredients.
1)In germ originated soybean isoflavones , the ratio between daidzin and daidzin is about 2:1. This is the remark of that source.
2)In soybean isoflavones from soybean meal, high content of daidzein and genistein higher than both germ and added source, because these two components can only be extracted naturally and cannot be added.
3) While the added product contains high content of daidzein and genistein. As long as these two components are too high, it can be deemed as added.
