Anthocyanin pigment/dye compositions and method of providing composition through extraction from corn

摘要

Anthocyanin pigments/dyes are extracted from corn kernels by adding corn kernels with less than 5% by weight of corn kernels comprising broken kernels to an aqueous medium to form an aqueous-corn medium. The corn kernels have in excess of 0.1 mg of anthocyanin pigment/dye per gram of corn kernel therein. The anthocyanin pigment/dye in the corn kernels has greater than 40% by weight of anthocyanin as an acid or acylated form of the anthocyanin. The aqueous corn medium is agitated at a temperature above 35° C. The solid corn kernels are separated from the aqueous corn medium to form an extract of anthocyanin in aqueous medium having less than 1.0% solids therein before concentration or purification steps are performed on the extract.
