Unsubstituted modified starch and methods for making the same

Abstract

An unsubstituted, crosslinked starch has a hot paste viscosity in a range of 100 cP to 1500 cP at pH 3 and 5.5 wt-% solids, a retrogradation enthalpy of 2.3 J/g or less at 1 week and 7 J/g or less at 4 weeks, and conclusion temperature of retrogradation of less than 75° C. The starch may be prepared from waxy tapioca, waxy rice, waxy-sugary-2 corn mutant, short chain waxy potato, waxy wheat, high phosphorylated waxy starch, or a combination of any two or more thereof. The starch may be crosslinked. The starch may be used in food products, nutritional products, pharmaceutical products, personal care products, paper products, and the like. A method of making the starch includes mixing a native starch with water to form a slurry; adjusting pH of the slurry to alkaline; and mixing a crosslinking agent with the slurry to effect a crosslinking reaction.
