ABSTRACT:
The orange, water-insoluble pigments monascorubrin and rubropunctatin elaborated by Monascus species can be converted to high purity red, water-soluble pigments by reaction with stoichiometric quantities of organic materials bearing a primary amine functionality. These pigments are suitable as colorants for a broad variety of edible formulations, especially those intended for human consumption, and often serve as suitable replacements for FD&C Red No. 2 and Red No. 4.
