What soybean varieties are suitable for producing soymilk and its products?
There are over one thousand varieties of soybeans grown around the world. Some have higher level of protein than others. You should select a light colored soybean variety relatively high in protein. Never use beans that have not matured properly in the field at the time of harvesting. Beans with moulds and green spots indicate major problem. As a rule of thumb, soybeans have 40% protein and 20% oil on a moisture free basis. Protein can be as high as 52% and as low as 30% with oil proportionately lower or higher. Moisture varies from 8% to 14%. Many processors prefer to use organically grown, non-GMO seed varieties. Fortunately, the flavor quality of soymilk made with airless cold grinding process used by ProSoya does not depend significantly on the soybean variety.
