What is Red Yeast Rice Extract?

Red Yeast Rice extract is a substance extracted from rice fermented by Monascus purpureus. This natural fermented product has a long history in traditional Asian diets and medicine. Red Yeast Rice extract contains a range of active ingredients, the most famous of which is monoacetyl lysine (Monacolin K), a substance known to lower cholesterol. Red Yeast Rice extract has received widespread attention for its cardiovascular health benefits.

Sources of Red Yeast Rice Extract

Red Yeast Rice extract powder is a substance extracted from the traditional East Asian food Red Yeast Rice (Red Yeast Rice), which undergoes a special fermentation process. Red Yeast Rice has a long history of production and is particularly popular in regions such as China and Japan. Not only is it a food additive, it is also gaining attention for its potential health benefits.

The process of making Red Yeast Rice starts with regular white rice. During the fermentation process, a microorganism called Monascus is added to the rice. This mold grows on rice, giving it its characteristic deep red color. This process not only changes the color of the rice, but also enriches it with a range of bioactive compounds, including a substance called tannins.

In East Asia, especially China, the production of Red Yeast Rice benefits from the special local fermentation process and climatic conditions. Suitable temperature and humidity are essential conditions for the red yeast fermentation process. These factors together guarantee its high quality. The traditional fermentation process has a decisive impact on the taste, color and quality of Red Yeast Rice.

In modern times, Red Yeast Rice extract powder has become a part of the health food and supplement industry. Red Yeast Rice extract powder is often used in the production of cholesterol management supplements because it contains compounds that may help regulate cholesterol levels in the blood. These supplements are primarily made from Red Yeast Rice sourced from China to maintain the heritage and purity of the product.

Although Red Yeast Rice extract powder has shown potential benefits in certain health areas, consumers should be cautious when using such products. It is recommended to consult a medical professional before using any supplement to ensure safety and suitability, especially considering that different people may react differently to these supplements. At the same time, quality control is also an important consideration, and consumers should choose products from reputable manufacturers and reliable sources.


Production process of red yeast rice extract

The production of Red Yeast Rice extract is a sophisticated and traditional fermentation process involving multiple steps

1. Raw material preparation

First, choose high-quality white rice as your base ingredient. Polished rice (rice with the outer skin removed) is usually chosen because the surface of polished rice is more suitable for microbial growth.

2. Sterilization and preparation

The selected rice is washed, soaked and then sterilized by steaming. The purpose of steaming is to kill bacteria and other microorganisms that may affect the fermentation process and to make the rice grains soft to facilitate the growth of Red Yeast Rice.

3. Inoculation with red yeast mold

After the cooked rice is cooled to a suitable temperature (usually around room temperature), spores of Monascus purpureus are added. This mold is responsible for giving Red Yeast Rice its characteristic color and composition.

4. Fermentation process

After inoculation, the rice is placed in a temperature- and humidity-controlled environment for fermentation. Fermentation temperature is usually maintained between 25°C and 30°C (77°F and 86°F), which is the ideal temperature for the growth of Red Yeast Rice. The fermentation process usually lasts about one to two weeks. During this period, Red Yeast Rice mold will grow on the rice, causing it to gradually take on its characteristic red color.

5. Inspection and drying

After fermentation is complete, the Red Yeast Rice is inspected to ensure that it is free of mold and other undesirable growth. Then, the fermented Red Yeast Rice needs to be dried to reduce the moisture content, prevent spoilage and extend the shelf life.

6. Extraction process

The dried Red Yeast Rice can be used directly as a food additive, or further extracted to make extract powder. Extraction usually uses alcohol or water as a solvent to separate the active ingredients in Red Yeast Rice, such as tannic acid.

7. Refining and packaging

The extracted liquid is filtered, concentrated and dried to form Red Yeast Rice extract powder.


Specifications of red yeast rice

ProjectSpecificationsDetails
AppearanceDark red powderRed Yeast Rice extract powder should be uniformly dark red in color with no obvious off-color particles. The shade of color may vary slightly depending on the degree of red yeast fermentation and the extraction process.
Total monoacetyl lysine content0.4%, 1%, 3%, 5%Total monoacetyl lysine content is a key indicator of the quality of Red Yeast Rice extract. The content ranges from 0.4% to 5% and needs to be accurately measured through modern detection technologies such as high-performance liquid chromatography (HPLC). Products in different strengths are available for different uses and dosage needs.
MoistureComply with standardsMoisture content should be controlled below 5% to ensure product stability and prevent microbial growth. Excessive moisture content may cause product deterioration and mildew.
Heavy metal contentComply with international food safety standardsContents of heavy metals (such as lead, mercury, arsenic and cadmium) must be strictly controlled below international food safety standards. For example, lead should not exceed 1 ppm (parts per million) and mercury should not exceed 0.1 ppm. These standards are usually set by international organizations such as the World Health Organization (WHO).
Microbiological limitsMeet food safety standardsMicrobiological indicators include total bacterial colonies, mold and yeast counts, coliforms and salmonella, etc. The total bacterial colony count should be controlled below 1000CFU/g, the number of molds and yeasts should be less than 100CFU/g, and E. coli and salmonella should not be detectable.
Additional detectionDetailed standardsAflatoxin B1 content should be less than 5 ppb (1 part per billion). Detect common pesticide residues to ensure compliance with relevant safety standards. If organic solvents are used for extraction, ensure that the residual solvent content meets safety standards.
