Hydroxypropylated starch as a processing aid to improve resistant starch total dietary fiber (TDF) retention in direct expansion extrusion applications

摘要

A composition comprising from about 3 % d.s.b. to about 35 % d.s.b. of a first starch, wherein the degree of substitution (DS) of the first starch with a hydroxypropyl group is from about 0.1 to about 0.6; from about 10 % d.s.b. to about 50 % d.s.b. of a second starch; and from about 15 % d.s.b. to about 87 % d.s.b. of a flour or a meal. A method, comprising extruding a composition as described above and from about 15 % total weight to about 25 % total weight water at a temperature from room temperature to about 200°C, to yield an extruded composition comprising less than about 5 % total weight water.
