Soybean meal

Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy.

[11] Although this implies that the tonnage of soybean meal fed to other species is relatively minor, such use is not unimportant.

For example, for rapidly growing lambs on low-protein feeds, soybean meal can be an important supplement to ensure adequate protein intake,[12] and partly because of its palatability, soybean meal is often recommended for use in starter rations when creep feeding lambs.

[13][14] Globally, about 2 percent of soybean meal is used for soy flour and other products for human consumption.

For several soy flour samples analyzed by various persons using high-performance liquid chromatography, daidzein content ranged from 226 to 2100 micrograms per gram, and genistein content ranged from 478 to 1123 micrograms per gram.
