Phorbol ester removal method in organic matter, method for producing high protein content organic matter, organic matter containing high protein, method for producing feed, and feed

摘要

The organic substance containing the phorbol ester component is decomposed and removed from the organic substance containing the phorbol ester component at a low cost and with a high processing capacity to produce a high protein-containing organic substance. The phorbol ester is decomposed by mixing and fermenting an organic substance containing the phorbol ester with Bacillus subtilis var. At this time, after mixing 4 parts by mass of an organic substance containing phorbol ester and 0.5 to 3 parts by mass of water and sterilizing at high temperature and high pressure, 0.004 to 0.2 parts by mass in 0.5 to 1 part by mass of water. A portion of Bacillus subtilis var. Natto dissolved is added and fermented at 30-50 ° C. for 2-4 weeks.
