Methods of anthocyanin extraction from colored corn cultivars

Procedes d'extraction d'anthocyanines a partir de cultivars de mais colores

Abstract

Methods of extracting anthocyanins from corn kernels are disclosed. In embodiments, the methods may include fractionating the corn kernels into their constituent component parts. After fractionating, the pericarp fiber may be separated from the constituent component parts of the corn kernels. The pericarp fiber may be steeped in an aqueous solution to extract anthocyanins from the pericarp fiber. After steeping, the aqueous solution may contain greater than about 40% by weight of total extractable anthocyanins present in the corn kernels prior to fractionating.
