"Green" Solution to Extracting BBI Cancer-Fighting Substance Offers PotentialIn an article published in American Chemical Society's Journal of Agricultural and Food Chemistry scientists have discovered that soybeans soaked in warm water naturally release a key cancer-fighting substance. Known as Bowman-Birk Protease Inhibitor (BBI), this substance has been studied in clinical trials to see if it is the reason that traditional Japanese diets seem to correlate with low cancer mortality rates. In laboratory experiments, BBI has stopped breast cancer cells from dividing.
Until now, extracting BBI from soybeans has involved a complicated industrialized process involving time spans of time and chemicals. This latest discovery provides a "green" way to extract BBI. It involves soaking soybeans in water heated to 122F. Funding for this research was in part provided by the U.S. Department of Agriculture.
