Abstract
The present invention relates to an enzymatically modified dietary fiber material particularly a soy fiber material of improved sensory properties including smoothness and mouthfeel characteristics. The modified fiber is formed by forming an aqueous slurry of a soy dietary fiber material and modifying or hydrolyzing the material with a process modifying dietary soy fiber and the resulting enzyme mixture which comprises a mixture of a cellulase and a carbohydrase. The degree of hydrolysis is sufficient to improve the sensory properties of the soy fiber material without substantially reducing the dietary fiber content thereof.
Claims24
A process for the production, from unmodified soy dietary fiber, of a modified soy dietary fiber material of improved sensory properties of smoothness and mouthfeel compared to the unmodified soy dietary fiber, comprising:
- a. forming an aqueous slurry of unmodified soy dietary fiber material having exposed surfaces;
- b. enzymatically modifying the slurry of soy fiber with an enzyme mixture of a cellulase and carbohydrase material for a time sufficient to smooth said exposed surfaces and thereby improve said sensory properties of smoothness and mouthfeel of the soy fiber but without a reduction greater than about 10% by weight in the total dietary fiber content of the modified soy fiber material.
A process for the production, from unmodified soy dietary fiber, of a modified soy dietary fiber material of improved sensory properties including mouthfeel characteristics and smoothness compared to the unmodified soy dietary fiber, comprising:
- a. forming an aqueous slurry of an unmodified soy fiber material having exposed surfaces;
- b. enzymatically hydrolyzing the slurry of soy fiber with an enzyme mixture comprising in parts by weight about 1 part cellulase and about 3 parts carbohydrase for a time sufficient to smooth said exposed surfaces;
- and
- c. jet cooking the hydrolyzed slurry of soy fiber followed by dewatering thereof.
