4 Claims

1. A process for forming a functionalised and amphiphilic dietary fiber, the process comprising:

admixing an enzyme and an aqueous suspension of dietary fiber selected from the group consisting of pea hull fiber, pulse hulls, bamboo fiber, cocoa fibers and coffee fibers, wherein the dietary fiber has a D₅₀particle size distribution of less than 30 microns after degradation by the enzyme, and the dietary fiber comprises less than 25 wt. % soluble fibers and at least 40 wt. % cellulose; and

denaturing the enzyme to form the functionalised and amphiphilic dietary fiber with the denatured enzyme adsorbed on a surface of the functionalised and amphiphilic dietary fiber.
