Red yeast rice is made by fermenting red yeast, monascus purpureus, with Non-Gmo rice. Its main coloring ingridient is monascus red. Red yeast rice has been used by the Chinese for many centuries as a food preservative, food colorant, spice, and ingredient in rice wine. It also has been used in China for over 1,000 years for medicinal purposes. Red yeast rice was described in an ancient Chinese list of drugs as useful for improving blood circulation and for alleviating indigestion and diarrhea. There is also growing interest in evaluating red yeast rice for use as a natural food dye andor preservative.
Characteristics
1. Steady with pH value
The alcohol solution of Red yeast rice is still red when the pH value is 11. The color of its aqueous solution turns only under the environment of strong acid or strong alkali.
2. Good heat resistance
Processed under 120° C for sixty minutes, the color of aqueous solution doesn't turn obviously. It can be seen that aqueous solution is very steady under the processing temperature of meat product.
3. Nice photostability
Red yeast rice is steady with light; And its alcohol solution is quite stable in ultraviolet radiation but its tint will be weakened in the strong sunlight.
4. Not affected by metal ion
Red yeast rice is quite stable to Ca2+, Mg2+ and Cu2+.
5. Not affected by oxidizer and reducer
When ascorbic acid, sodium sulfite or hydrogen peroxide are added in the Red yeast rice solution, its color isn't be changed.
6. Good coloring performance
Red yeast rice is easy to color protein or raw materials with more protein, color on which is difficult to remove after coloring.
7. Solubility
It is solube in fat, but not solube in water and glycerin.
8. Good safety
Red yeast rice has very good safety. Animal experiment indicates that any food made of edible Red yeast rice does not cause any acute chronic poisoning.
Application
1. Condiment(braise meat, preserved beancurd, jam);
2. Food(meat, juice, drink, wine, beverage, candy, noodle, health food, cake, sanitaniam vinegar and etc. );
3. Medicine(Medicine colorant, Medicine ingredients etc);
4. Cosmetic.
