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.
