What is Monascus Red Pigment?
Monascus Red Pigment is a secondary metabolite of Monascus. It is generally considered to be a mixture of polyketone compounds, and there are two main categories: red and yellow. monascus purpureus red pigment is mainly produced by solid-state fermentation and liquid fermentation. Monascus pigment is obtained by fermenting and cultivating Monascus, then separating and purifying, and finally preparing monomers. Studies have shown that liquid fermentation has a shorter cultivation time, lower production costs, and better product quality. Monascus pigments are mainly composed of different chemical structures and similar properties.
A mixture of red, orange, and yellow pigments. There are 10 known structures, and there are 6 fat-soluble pigments mainly studied. They are Momscombramine and Rubmpunctamine in red, Monascombm and RubroDuIlctatin in orange, and M0nascin and Ankanavin in yellow.

How did the Monascus Red Pigment come about?
The biosynthetic pathways of Monascus secondary metabolites Monascus pigment, MonacoillK, and citrinin were initially similar. They are all first condensed with acetyl-CoA and malonyl-CoA as substrates. The biosynthesis of Monascus pigment is usually the reaction of acetyl-CoA and malonyl-CoA to generate hexanone chromophore under the reaction of type I polyketides 1'rIlthase (PKS).
The Monascus Red Pigment was obtained by transesterification between the hexanone chromophore and the medium-chain fatty acid produced by the fatty acid synthesis pathway. Then Monascus orange pigment is reduced to Monascus yellow pigment or Monascus orange pigment undergoes ammonia addition reaction (amillatioll) with an amino acid to generate Monascus red pigment.
Features of Monascus Red Pigment:
Color prices and shades
Monascus pigments are mixed shades consisting mainly of two components, yellow and red, but less yellow than red. Therefore, it is visually felt that the Monascus pigment is dark red.
water-soluble
The water-soluble pigments in Monascus pigments are related to the pH of the solution and are easily soluble in alkaline and neutral solutions. At pH<4, the solubility of Monascus pigment gradually decreased until precipitation occurred.
Thermal stability
The thermal stability of Monascus pigment is good. For example, its thermal stability is better than that of synthetic pigments such as amaranth and carmine. The heat resistance of natural pigments is also relatively good.
Light stability
monascus purpureus red pigment has good stability under acid-base or thermal conditions but is unstable to light and prone to photochemical reversal. It decreases with the increase of light intensity and decreases with the increase of light time.
the stability of metal ions
In the storage of Monascus pigment, contact with certain heavy metal ions should be prevented.
Application:
Application in meat products
Monascus pigment has good coloring ability and strong antibacterial ability and is safer than nitrite, so it has a good effect in food processing.
Application in the wine industry
The functional wine developed by fermentation will gradually increase in demand with the strengthening of the concept of healthy nutrition in the future. The anti-fatigue and antioxidant properties of red yeast rice wine are very attractive to people.
Application in condiments
Monascus pigments are mostly used in the production of soy sauce in condiments. Monascus pigment has a good coloring effect on protein, increases the ruddy degree of soy sauce, and makes the color of soy sauce better.
Application in pasta products
Mainly used in red yeast bread, red yeast tuckahoe steamed bread, red yeast cake, red curved noodles, and other noodle products.
The addition of red yeast rice makes the steamed bread better in color, structure, elasticity, and stickiness. Red yeast bread is the red yeast bread that is added in bread production, and the color of the bread becomes reddish and more fragrant than ordinary bread.
Application in the textile industry
monascus purpureus red pigment has excellent coloring ability and is relatively stable. It is feasible as a natural dye, which is consistent with the ecological civilization society advocated now and is green and environmentally friendly.
