General description

Soybean flour is produced from the leguminous plant, soybean. It is a source of nine essential amino acids and has lesser carbohydrates and fat. Soybean flour is an excellent protein source. It is highly bioavailable and its isoflavone content prevents cardiovascular problems.

Application

A defatted, slowly available protein nutrient.
Soybean flour has been used:
  • for optimizing Triton X-114 (TX-114) based lipopolysaccharide (LPS) extraction
  • as a protein supplement in the in vitro fermentation of rumen fluid
  • as a protein supplement in batch culture of bovine digesta to assess its degradation

Biochem/physiol Actions

Some studies have shown that soybean flour can be carcinogenic and induce pancreatic cancer in rats.
