The present invention relates to a process for producing a black tea product with enhanced sensorials. The people who prefer to consume black tea are unable to get a good amount of catechins, because, in black tea the amount of catechins is significantly less than that of green tea. Therefore there is a need for providing a tea product which has relatively high amount and catechins high amount of theaflavins and high amount of polyphenols made by a process without addition of any exogenous theaflavins and / or catechins and which also has the sensorials of black tea. It is an object of the present invention to provide a process for producing a tea product with a relatively high amount of catechins and theaflavins without the addition of any exogenous theaflavins and / or catechins. The present inventors have surprisingly found that tea products obtained by a process involving a step of anaerobic incubation at specific temperatures and for specific durations provide a tea product with improved sensorials and thereby satisfying one or more of the objects of the invention.

The invention discloses an anaerobic fungus and a method for producing formic acid by fermenting rice straw with the same, belonging to the field of biology. The anaerobic fungus (Piromyces sp.) Yak TZF, CGMCC NO: 13392 has the ability to produce formic acid in large quantities. The method for producing formic acid by fermenting rice stalks with the anaerobic fungus comprises the following steps: taking rice stalks and pure culture of anaerobic fungi (Piromyces sp.) Yak TZF as the inoculum, adding compound antibiotics and prepared chloramphenicol at the same time, After anaerobic culture at 39°C for 7 days, the concentration of formic acid produced reached 27.9mM. The present invention is characterized in that: 1. The method and process of the present invention are more convenient and convenient, mainly to ensure an anaerobic environment. 2. The method of the present invention only needs to pulverize and air-dry the stalks, and does not need to peel the stalks. 3. The concentration of formic acid produced by the method of the present invention is very high.

The method of the invention can prepare the extract with high extraction rate, and the obtained extract has stable performance.

The invention belongs to the technical field of food processing, and relates to a dietary supplement rich in soybean polypeptide and a preparation method thereof. The method comprises the following steps: A. preparing a fermentation base material, dissolving soybean polypeptide in water, adding sugar, homogenizing to obtain a homogenate liquid, cooling after sterilization, B. preparing a mother starter, taking a dairy solution, cooling after sterilization, and putting it in the dairy solution Add compound lactic acid bacteria suspension, anaerobic culture to obtain the mother starter, C, prepare fermentation broth, put the fermentation base material under sterile conditions, adjust the temperature to 35-42°C, then add an appropriate amount of mother starter, and cultivate for 3-6 Hours, D, hydrolyzed, the temperature of the fermented liquid is raised to 45-55°C, hydrolyzed at 45-55°C to obtain a hydrolyzed liquid, E, dried, an appropriate amount of cyclodextrin is added to the hydrolyzed liquid, dried to remove moisture, and dried powder. The invention has rich nutrition, good taste and is easy to be absorbed by human body.

The invention relates to an anaerobic culture bag with an anaerobic indicator, which includes a bag body and an anaerobic indicator, the anaerobic indicator includes a casing, a first piston and an opening device, and the casing has a piston chamber The bag body is provided with a one-way valve, and when the gas pressure in the bag body is greater than the air pressure in the piston chamber, the gas in the bag body flows into the piston chamber through the one-way valve The opening device is arranged on the housing, and is used to connect the mouth of the ampoule bottle containing the anaerobic indicator. When the pressure in the piston chamber is higher than a preset value, the opening device is triggered to Open the mouth of the bottle so that the gas in the piston cavity enters the ampoule. The anaerobic culture bag with anaerobic indicator provided by the present invention allows the gas in the piston cavity to enter the ampoule to realize the function of testing the gas in the anaerobic culture bag, effectively improving the anaerobic culture bag anaerobic Oxygen test efficiency.

The invention discloses a floating type double-bed micro-porous membrane water body repairing device which comprises a floating plate, a photovoltaic assembly, an air conveying pump, a storage battery, a control center, an anaerobic jar, a liquid conveying pump, an aerobic bed, an anaerobic bed and a connecting rope. The aerobic bed and the anaerobic bed are sequentially suspended below the floating plate in series. Air is introduced into the aerobic bed so as to accelerate the reproduction of aerobic bacteria. The anaerobic bed conveys anaerobic bacteria through the anaerobic jar. Filled biological rope filler is beneficial for the adhesion reproduction of bacteria. Small holes are formed in shells of the aerobic bed and the anaerobic bed so that bacteria diffusion can be facilitated. Thestructure of the repairing device is beneficial for bacteria reproduction; a winding machine, an ultrasonic distance detector, a water body eutrophy detector, an electric propeller, an electric rudder, an anchor and a remote controller are additionally arranged, the water body eutrophy degree is judged, and the repairing device is automatically controlled by a control center or remotely controlled by manpower to move in a water body for repairing and purifying; aerobic bacteria and anaerobic bacteria are used for repairing the water body without being interfered with by each other, the growthand reproduction of the bacteria are rapid, and the water body repairing and purifying effect is good.

The invention discloses a bioelectrochemical method for removing pig manure odor, belonging to the technical field of bioelectrochemical deodorization. The method comprises the following steps: (1) adding pig manure into an anaerobic fermentation tank, and at the same time adding Escherichia coli suspension, culture medium, etc. The electrolytic mixture is inoculated into pig manure, and then the inoculated pig manure is placed in the anode electrolyzer, and pig manure is added to the cathode electrolyzer at the same time; (3) Potential is applied to the anode electrolyzer and medium is added for anaerobic cultivation , the odor of pig manure in the cathodic electrolyzer will be gradually removed during this process. In the present invention, by constructing a microbial electrolysis circuit, ammonium chloride is used as a nitrogen source to domesticate microbial mixed bacteria, so that the domesticated microorganisms can effectively decompose H in pig manure. 2 S, ammonia and other odor molecules, thereby realizing the effect of deodorizing pig manure. The method of the invention can obviously improve the environment of the pig house, and has a good application prospect.
