Knowledge Guidance of Processing Traditional Chinese Medicine: Fermentation Method —— Overview

Under certain temperature and humidity conditions, the method of foaming and coating drugs through the catalytic decomposition of mold and enzyme is called fermentation.

2. The main purpose of fermentation

Change the original performance, produce new therapeutic effects and expand the variety of drugs. For example, six melodies, lobster sauce.

Enhance the curative effect. Such as Banxia Qu.

3. Fermentation operation method

According to different varieties, it is processed by different methods and fermented in an environment with suitable temperature and humidity. Commonly used methods include mixed fermentation of medicinal materials and flour, such as medicated leaven, Jianqu, Banxia leaven and Aquilaria sinensis leaven. Another method is to ferment directly with medicinal materials, such as lobster sauce and herbal soup.

Fermentation conditions and processes are metabolic processes of microorganisms, so the conditions for their growth and reproduction should be met in the preparation process.

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

4. Quality requirements of fermented products

The smell should be fragrant, not moldy or rancid.

The surface of the block is yellow and white, and it is better to have spots inside. The quality of black is poor.

5. Preventive measures

Before fermentation, raw materials should be sterilized and insecticidal to avoid the influence of miscellaneous bacteria on fermentation quality.

The fermentation process must be completed at one time without interruption or pause.

Temperature and humidity have great influence on fermentation speed. If the temperature is too low or too dry, the fermentation speed is slow or even impossible to ferment, while if the temperature is too high, the mold can be killed and unable to ferment.
