NATURAL BLUE ANTHOCYANIN-CONTAINING COLORANTS

摘要

The present invention is directed to natural blue anthocyanin-containing colorants comprising fractions of anthocyanin molecules separated from anthocyanin-containing vegetable and fruit juices and extracts. Anthocyanin fractions are separated at a select pH based on differences in polarity of the anthocyanin molecules in the anthocyanin-containing vegetable and fruit juices and extracts. The invention is directed to the anthocyanin fractions providing color characteristics similar to those provided by the synthetic blue colorant, FD&C Blue No. 1. The present invention is also directed to natural green colorants comprising the natural blue anthocyanin-containing colorant and a natural yellow colorant. The present invention is further directed to edible products comprising the natural blue anthocyanin-containing colorants.

主权项

1. A natural blue anthocyanin-containing colorant sourced from vegetable, fruit or combinations thereof, comprising a selectively separated mixture of anthocyanins, wherein the colorant when in an aqueous solution at pH 8.0 has a maximum absorbance of 615 nm to 635 nm.
