Environmental Friendly Soy Bean Harvest and Cancer Prevention.

Research published in ACS’ Journal of Agriculture and Food Chemistry recently concluded that soybeans soaked in warm water may become a healthier way to obtain a soy substance to  fight cancer. The substance is currently manufactured in a complicated and time-consuming industrial process that does not have the most healthy outcome.

The substance called Bowman-Birk Protease Inhibitor (BBI) has shown promise for preventing some types of cancer. Human test results included evidence from the Japanese diet  that contains large amounts of soybeans that might underpin the low cancer mortality rates in that country. A problem with the current supply of BBI is that extracting it from soybeans is a time-consuming process and requires harsh chemicals. The current researchers wanted to see if there was a better (greener, more environmentally friendly) way to obtain BBI. The found that incubating the soybean seeds in water at 122 degrees Farenheit released large amounts of BBI that can easily be harvested from the water.  The water was tested on and stopped breast cancer cells from dividing. The researchers concluded “The abundance of BBI in soybean seed extracted by incubating the seeds in warm water provides a simple and alternative method to isolate this low molecular weight protein.”
