The production of a large amount of

The production of a large amount of yellow Monascus pigments
by extractive fermentation provides a chance for preparation
of yellow Monascus pigments. In the present work,
extraction of Monascus pigments from fermentation broth by ionic
liquid based microemulsion extraction and removal of orange
Monascus pigments to achieve yellow Monascus pigments via selective
aminophilic reaction between orange Monascus pigments and
MSG (monosodium glutamate) as well as further purification of
yellow Monascus pigments by crystallization were carried out.
Some basic characters of yellow Monascus pigments, such as aminophilic
reaction between yellow Monascus pigments and amino
acids, were also evaluated
