Red yeast rice is fermented with Monascus, so the first step is to prepare Monascus. First prepare a culture medium suitable for the growth of the bacteria and inoculate the bacteria into the culture medium. After a period of time, find colonies that grow well and inoculate them onto new culture media. High-quality Monascus colonies can be obtained by repeating 3 times.

The next step is to prepare the spore suspension. Add an appropriate amount of sterile water to the container containing the colonies and allow the spores to mix into the sterile water. Then transfer the solution to another container, add glass beads and shake well to get the spore suspension.

Process raw materials. The raw material of red yeast rice is rice, so high-quality rice must be selected to remove impurities and improve purity. Then add an appropriate amount of cold water and soak it at room temperature for a day so that the rice grains can fully absorb the water. After soaking, put the rice in a steamer and steam it repeatedly.

Mix the prepared spore suspension thoroughly with rice, and then ferment and culture it for about 20 days. During this period, there must be sufficient light and appropriate air contact.

After the rice is fermented, take it out to air-dry and dry it in the sun for several hours, but avoid direct sunlight.

After these steps, the production of red yeast rice is completed.
