In this paper,the stability of Monascus yellow pigment prepared in our lab were investigated.

BACKGROUND AND AIM: To investigate the toxicity in SD rats fed continuously with monascus yellow pigment.

Primary study on the production of Monascus pigment from bran by fermentation;

Study progress on controlling metabolism in Monascus pigment;

Study on inclusion compound of monascus pigment with β-cyclodextrin;

Optimization of cultivation conditions for Monascus pigments by solid fermentation of Monascus;

Fed-batch fermentation of Monascus pigments in shakeing flask by Monascus purpureus JR

Effects of ultrasonic assist on extraction of Monascus pigments

The production and utilizations of red pigment in China has a long history and is one of cultural treasures in our country.

The strain of Monascus purureus 721 can not only produce red pigment,but also produce ergosterol.

That produces more ergosterol,two Monascus strains are settled to experiment on the factors of produce red pigment.

Study on the stability of monascus pigments added antioxidant;

The red, orange and yellow pigments were obtained by separating monascus pigments powder, their maximum absorbance were 490±5nm(red pigments), 374±5nm/490±5nm (orange pigments) and 367±5nm (yellow pigments).
