Abstract
Disclosed is a process for preparing bleached soy fiber suitable for human consumption. The soy fiber is extremely white and has a very high percentage of total dietary fiber with a low concentration of non-fiber components, such as starch, fat, protein and lignin.
Claims33
A method for making a bleached soy fiber, comprising:
- a) combining soy hulls with water, an amount of peroxide radical donor effective to bleach the soy hulls and a pH regulating amount of buffer, to form a composition having a pH from about 5.5 to about 8.5;
- b) isolating bleached soy fiber from the composition to give a yield of between 10 and 50% of bleached soy fiber;
- and
- c) optionally dewatering and drying the bleached soy fiber.

2 more elements
A method for making bleached soy fiber, comprising:
- a) combining between about 1 to about 50 parts by weight soy hulls with about 100 parts by weight water, with an amount of peroxide radical donor effective to bleach the soy hulls and a pH regulating amount buffer, to form a composition having a pH from about 5.5 to 8.5;
- b) isolating bleached soy fiber from the composition;
- and
- c) optionally dewatering and drying the bleached soy fiber.
