1. Definition

After purification or treatment, under certain temperature and humidity conditions, due to the catalytic decomposition of mold and enzymes, the drug will foam and produce. The method of dressing is called the fermentation method.

2. The main purpose of fermentation

Change the original properties, produce new therapeutic effects, and expand the variety of drugs. Such as Liushenqu and light tempeh.

Enhance efficacy. Such as Pinellia melody.

3. Fermentation operation method

According to different varieties, different methods are used for processing, and then placed in an environment with suitable temperature and humidity for fermentation. Commonly used methods include mixed fermentation of medicinal materials and flour, such as Liushenqu, Jianqu, Pinellia ternata, Agarwood, etc. Another type of method is to directly use medicinal materials for fermentation, such as light tempeh, Baiyao Jian, etc.

Fermentation conditions and fermentation process are processes of microbial metabolism. Therefore, conditions for their growth and reproduction should be met during preparation.

[Bacteria, nutrients (culture medium), water, temperature, relative humidity, other aspects]

4. Quality requirements for fermented products

Odor requirements Fragrant without musty or rancid smell.

The mold on the surface of the curved block is yellowish white, and it is better if there are spots inside. Poor black quality.

5. Precautions

Raw materials should be sterilized and insecticidal before fermentation to prevent miscellaneous bacteria from affecting the quality of fermentation.

The fermentation process must be completed at one time and cannot be interrupted or paused midway.

Temperature and humidity have a great influence on the speed of fermentation. If the temperature is too low or too dry, the fermentation speed will be slow or even impossible. If the temperature is too high, mold will be killed and fermentation will not be possible.
