  • Soybean hydrolyzate
    Patent number: 4882180
    Abstract: A soybean hydrolyzate is disclosed. The hydrolyzate is of a high nutritional value and excellent in protein absorbability.

Consequently, the hydrolyzate is very valuable food as protein source.The hydrolyzate is characterized by that the soluble fraction of the hydrolyzate contains amino nitrogen in an amount in the range from 5 to 20%, preferably from 10 to 15% of the total nitrogen of said fraction. The hydrolyzate is prepared by pulverizing soybean, adding water to the pulverized soybean to form a slurry of a solid content in the range from 1 to 20%, heating the slurry at a temperature from 60.degree. to 100.degree. C. for a period from 5 to 180 minutes, homogenizing the slurry under a high pressure and hydrolyzing the homogenates with a neutral protease produced by Bacillus subtilis.
