Abstract
A method for fractionation of soybean protein into a 7S globulin-rich fraction and an 11S globulin-rich fraction which comprises treating a soybean protein-containing solution with an enzyme or an enzyme preparation having an activity of decomposing phytic acid to thereby separate into a soluble fraction and an insoluble fraction at a specific pH value.
Claims7
A process for producing soybean 7S globulin and 11S globulin, which comprises:
- treating a soybean protein-containing solution with an enzyme or an enzyme preparation having an activity of decomposing phytic acid, and
- adjusting the solution to a pH of 5.6 to 6.6, to thereby separate into a soluble fraction which is 7S globulin-rich fraction and an insoluble fraction which is an 11S globulin-rich fraction.
