Natural food colorant produced by Monascus fermentation is considered to be one of themost successful examples of the world's natural colorant product by microbial fermentation.Nowadays, there are about12kinds of Monascus which can produce at less3sorts ofpigments, including red pigment, yellow pigment and orange pigment. In this study, we aim tolay a solid foundation for producing different color tune (red pigment/yellow pigment/orangepigment) by strains screening, mutation as well as the manners of Monasc...
