Problems solved by technology

Therefore, pure fermentation of tea leaves is difficult to achieve in actual production.
[0009] Faced with the above defects, artificial inoculation of solid-state fermentation of Pu'er tea is actually difficult to achieve, and the Pu'er tea paste produced by using the traditional method of "stacking" Pu'er tea as raw material is also difficult to avoid the harm caused by miscellaneous bacteria

Embodiment 1

[0037] Such as figure 1 The shown Pu'er tea combined fermentation device specifically includes a main fermentation tank 1, a flower basket 2, a material liquid distribution screen 3, an intermediate valve 4, a circulating pump 5, a plate heat exchanger 6, a liquid addition valve 7, and a liquid level gauge 8. , Connect the temperature detector interface 9, connect the gas detector interface 10, exhaust valve 11, steam valve 12, intake valve 13, safety valve 14, breathing mask 15, pressure gauge 16, exhaust valve 17, support ear 18. Discharge valve 19, feed valve 20, sterile water tank 21, edible fungus fermentation tank 22, Pu'er tea strain fermentation tank 23, connecting pipes and instruments. The sealing and locking type of the tank cover of the main fermentation tank 1 and the tank body adopts a self-locking wedge engagement method, which is convenient to open. One or several loading flower baskets can be placed inside the main fermentation tank. The loading flower baskets ...

Embodiment 2

[0045] According to Example 1 fermentation device.

[0046] The specific process operation steps are different from Example 1:

[0047] Step 3: Continue to inject steam through the steam valve 12 until the temperature in the tank reaches 80°C, keep it warm for 15 minutes for pasteurization, and turn off the steam;

[0048] Step 4: Cooling and circulating to the temperature required for fermentation of 26°C, by adjusting the temperature of the hot and cold water entering the heat exchanger to keep the circulating feed liquid at the temperature required for fermentation, and keep the feed liquid circulating;

[0049] Step 5: Open the air inlet valve 13 and introduce oxygen to make the oxygen content of the gas in the tank reach 45%, ferment for 4 days, and then input sterile air through the air inlet valve 13 to replace the gas in the tank, so that the gas composition in the tank remains the same as the air composition Same, 4 days of fermentation. The above process controls the ferment...

Embodiment 3

[0051] According to the fermentation device of Example 1. The specific process operation steps are as follows different from Example 1.

[0052] Step 3: Continue to inject steam through the steam valve 12 until the temperature in the tank reaches 85°C, keep it for 15 minutes for pasteurization, and turn off the steam;

[0053] Step 4: Cooling and circulating to the temperature required for fermentation of 32°C, by adjusting the temperature of the hot and cold water entering the heat exchanger to keep the circulating feed liquid at the temperature required for fermentation, and keep the feed liquid circulating;

[0054] Step 5: Open the intake valve 13 and introduce oxygen to make the oxygen content of the gas in the tank reach 40%, and ferment for 2 days, and then input sterile air through the intake valve to replace the gas in the tank to keep the gas composition in the tank consistent with the air composition , Fermentation for another 6 days, the above process controls the fermen...

Abstract

The invention discloses a combined fermentation process of edible fungus polysaccharide Pu'er tea. The process adopts a combined fermentation device. The combined fermentation device comprises the following components: a main fermentation tank, an edible fungus fermentation tank, a Pu'er tea strain fermentation tank, a loading basket, a feed liquid distribution screen, a circulating pump, a plateheat exchanger, a liquid level meter, a steam valve, an air inlet valve and the like. The process comprises the following steps: preparing edible fungus mycelium fermentation liquor in the edible fungus fermentation tank, preparing Pu'er tea strain fermentation liquor in the Pu'er tea strain fermentation tank, loading the loading basket of the main fermentation tank with tea leaves, putting the basket into a tank for sterilization, adding sterile water, performing circular cooling, adding the two fermentation liquors into the main fermentation tank for fermentation, and after the fermentation,performing heating, sterilization, extraction, filtration, purification, concentration, drying and packaging on the fermentation liquors so as to obtain the edible fungus polysaccharide Pu'er tea. The process combines edible fungus polysaccharide fermentation with Pu'er tea liquid state fermentation in one system, achieves combined fermentation, and has the advantages of being short in fermentation period and good in sanitary condition.

Description

Technical field [0001] The invention relates to the fields of fermentation industry and food industry, in particular to a combined fermentation process of edible fungus polysaccharide Pu'er tea. Background technique [0002] Polysaccharides, namely polysaccharides, refer to high molecular polymers formed by multiple (generally 10-20) identical or different monosaccharide units combined by glycosidic bonds. In the 1970s, the anti-tumor activity of lentinan was first confirmed by Japanese scholar Chihara Haneda. A large number of medical and pharmacological studies have shown that polysaccharide compounds have a strong inhibitory effect on tumor cells, and also show very important functions in anti-aging, anti-oxidation, anti-virus, and enhancement of body immunity. As a unique biological effect modifier, polysaccharides have no toxic side effects on normal cells, and have long been used in clinical adjuvant therapy and diet therapy for tumors and other diseases. [0003] There are...
