Description

Production method of lentinan beverage
Technical Field
The invention belongs to the technical field of preparation methods of edible fungus fermentation type functional foods, and particularly relates to a production method of a lentinan beverage.
Background
The mushroom has very high nutritive value, is important edible and medicinal fungi and seasonings for people, and is also a natural functional food. Shiitake contains more than ten kinds of amino acids, and 7 kinds of amino acids necessary for human body, such as isoleucine, lysine, phenylalanine, methionine, threonine, valine, etc., are contained therein. Every hundred grams of dried shiitake contains 13 grams of protein, 1.8 grams of fat, 54 grams of carbohydrate, 7.8 grams of crude fiber, 4.9 grams of crude ash, and various vitamins and mineral salts; 124 mg of calcium, 415 mg of phosphorus and 25.3 g of iron in the ash; the vitamins comprise 0.07 mg of B1 (thiamine), 1.13 mg of B2 (riboflavin), 18.9 mg of B3 (vitamin PP and nicotinic acid) and 260 mg of provitamin D (ergosterol). The mushroom has strong inhibition effect on cancer cells, the inhibition rate on mouse sarcoma S-180 is 97.5%, and the inhibition rate on ehrlich ascites tumor is 80%. Lentinus Edodes can be used for preventing and treating cancer, diabetes, pulmonary tuberculosis, infectious hepatitis, neuritis, dyspepsia, constipation, and reducing weight. The Lentinus Edodes also contains double-stranded ribonucleic acid, can induce production of interferon, and has antiviral effect.
The main components of the lentinus edodes are polysaccharides and unsaturated fatty acids, and the lentinus edodes also contains a large amount of ergosterol and mycosterol which can be converted into vitamin D, and lentinan is an effective active component extracted from high-quality lentinus edodes sporocarp and has a molecular formula as follows: (C)6H10O5) The lentinan extracted by hot water can adjust the activity of T cells with immune function in human bodies, and can reduce the capacity of methyl cholanthracene to induce tumors, researches show that the active polysaccharide ingredient β - (1 → 3) -D-glucan of lentinus edodes is effective in inhibiting heterogenous, homologous and even hereditary tumors, and the lentinan mainly treats gastric cancer, liver cancer and bladder cancer which can not be operated or recurred, can relieve symptoms by using the lentinan, improve the immune function of patients, and correct trace element imbalance, can also promote the proliferation of T, B cell lymphocytes, improve the activity of NK cells, resist viruses, protect the liver and the like, is an anticancer auxiliary drug which has the effect of immune regulation by improving the autoimmunity, and resists diseases by improving the autoimmunity is the best treatment method at present, in particular, the biological activity of the lentinan has the following advantages:
1. anti-tumor activity of lentinan
Lentinan has anti-tumor effect, and has no adverse side effects of chemotherapeutic drugs. Lentinan is induced to produce a cell factor with immunological activity after entering into the antibody, and under the comprehensive action of the cell factors, the immune system of the organism is enhanced, and the cell factor plays a role in defending and killing tumor cells.
Lentinan exerts anti-tumor activity by activating macrophages, enhancing antibody-dependent cell-induced cytotoxicity (ADDC); in addition, lentinan also dilates and bleeds the blood vessels at the tumor site, resulting in hemorrhagic necrosis and complete regression of the tumor.
2. Immunomodulation of lentinan
The immunoregulation function of lentinan is an important basis of its biological activity. Lentinan is a typical T cell activator, promotes the production of interleukins, and also promotes the function of mononuclear macrophages, and is considered to be a specific immunopotentiator. The immune function is characterized in that the immune function can promote the generation of lymphocyte activating factor (LAE), release various helper T cell factors, enhance the phagocytosis rate of host peritoneal macrophages and recover or stimulate the function of helper T cells. In addition, lentinan also promotes antibody production and inhibits macrophage release.
3. Antiviral activity of lentinan
It is considered that shiitake mushroom contains a double-stranded ribonucleic acid which stimulates reticulocytes and leukocytes of the human body to release interferon, and interferon has an antiviral effect. The Lentinus Edodes mycelium extract can inhibit cell adsorption of herpesvirus, and can be used for preventing and treating various diseases caused by herpes simplex virus and cytomegalovirus. A substance is extracted from cultured shiitake mushroom mycelia, and has effects in recovering T lymphocytes infected by AIDS virus, stimulating macrophage, and promoting antibody production to treat AIDS, with high safety and no adverse side effect.
The sulfated lentinan has been found by scholars to have activity against the Human Immunodeficiency Virus (HIV) and to interfere with the adsorption and invasion of retroviruses and other viruses. Japanese scholars reported that a sulfated derivative of dextran obtained from fruiting body of Lentinus edodes with good antitumor effect could inhibit HIV activity.
4. Lentinan anti-infection effect
Lentinan is reported to increase macrophage function. Lentinan has inhibitory action on Abelson virus, adenovirus 12 and influenza virus infection, and is a good medicine for treating various hepatitis, especially chronic migratory hepatitis.
Current applications of lentinan include:
1. application of lentinan in medicine field
Lentinan has good therapeutic effect in treating gastric cancer, colon cancer, lung cancer, etc. As an immune adjuvant, lentinan is mainly used for inhibiting the occurrence, development and metastasis of tumors, improving the sensitivity of the tumors to chemotherapeutic drugs, improving the physical condition of patients and prolonging the life of the patients.
The lentinan can be used in combination with chemotherapeutic agent, and has effects of reducing toxicity and enhancing efficacy. The selectivity of the chemotherapeutic drugs for killing tumor cells is poor, normal cells are also killed, toxic and side effects are generated, and chemotherapy cannot be performed according to the quantity in time; because of insufficient dose of chemotherapy, drug resistance of tumor cells is often caused, which becomes refractory cancer and affects the curative effect. The lentinan is taken in the chemotherapy process, so that the curative effect of chemotherapy can be enhanced, and the toxic effect of the chemotherapy can be reduced; meanwhile, the incidence rate of leucocyte reduction, gastrointestinal toxicity, liver function damage and vomiting of the patients in the chemotherapy process are obviously reduced. This fully demonstrates that the combination of lentinan with chemotherapy can enhance the efficacy, reduce the toxicity, and enhance the immune function of the patient's body.
Lentinan can be used in combination with other medicines for treating chronic hepatitis B, and can improve the negative conversion effect of hepatitis B virus marker and reduce the side effect of antiviral medicines. In addition, lentinan can be used to treat tubercle bacillus infection.
2. Application of lentinan in health food field
Lentinan is a special bioactive substance, a biological response enhancer and regulator, and can enhance humoral immunity and cellular immunity. The antiviral action mechanism of lentinan may lie in that it can raise immunity of infected cell, raise stability of cell membrane, inhibit cytopathy and promote cell repair. Meanwhile, lentinan also has anti-retroviral activity. Therefore, lentinan is a health food against influenza to be developed.
The lentinan powder and lentinan capsules which are commonly used in clinic at present have the effects of activating cellular immunity, regulating various humoral immune factors, inducing α -interferon generation, regulating organism immune response reaction, inducing leukocyte infiltration to tumor, causing vasodilatation, bleeding and necrosis of tumor parts, preventing combination of virus and host cells, improving SOD activity, inhibiting MDA generation, resisting lipid oxidation, reducing cholesterol, regulating carbohydrate metabolism, improving carbohydrate tolerance, expanding gastrointestinal tract to generate satiety, reducing appetite, reducing blood sugar and the like.
It is often combined with tegafur (FT207), Adriamycin (ADR) and mitomycin (MMC) clinically to treat the stomach cancer which can not be operated or recurred. Can also be used for treating colorectal cancer, lung cancer, breast cancer, acute and chronic leukemia, and chronic viral hepatitis B. For the patients with late stage cancer with distant organ metastasis, the composition can be used in chemotherapy to improve the general condition of patients, improve therapeutic effect, and prolong life.
But the accidental adverse reactions are as follows:
① shock is rare, so it should be closely observed after administration, and should be stopped and properly and timely treated when symptoms such as abnormal mouth, aversion to cold, abnormal heart rhythm, blood pressure drop, and dyspnea occur.
② when rash and redness occur, the medicine should be stopped in time and should be treated if necessary.
③ the respiratory system should be closely observed due to chest compression and throat stenosis, and the administration speed should be slowed down
④ nausea, emesis, and anorexia.
⑤ headache, heaviness of head and dizziness in nervous system.
⑥ decrease of blood, occasional red, white blood cells and hemoglobin.
⑦ and other symptoms such as fever, sweating, and flushing.
Lentinan products are various, and mainly comprise injections, capsules, tablets, powder and the like on the market, lentinan powder and lentinan capsules are commonly used clinically, most products are extracted from lentinan sporocarp, the workload is large, the efficiency is low, the cost is high, the pollution is serious, the price is high, and adverse reactions such as shock, rash, nausea, vomiting, inappetence, dizziness and the like can be found when the lentinan capsules are taken. In addition, probably because the strain is degraded quickly, the technical difficulty of the production process is large, and the requirement on technical personnel is high, products of lentinan drinks (liquid beverages) are not seen so far, and in patent applications related to lentinan, the methods for producing the lentinan by liquid are few, and only tests in laboratories have not been reported, and no large-scale production is reported. Therefore, there is a need for further improvement of health food of shiitake mushroom and a method for preparing the same, and providing a more effective, safer, mass-producible product.

Detailed Description
The present invention will be described in detail with reference to the following examples:
a production method of lentinan beverage comprises inoculating Lentinus edodes strain into rejuvenation culture medium of different types, and culturing for 18-22 days to rejuvenate the strain; inoculating the strains with good growth after rejuvenation into a liquid culture medium, and performing multi-stage amplification culture, wherein each stage is subjected to shake culture at 25 ℃ for 5-7 days, and the inoculation amount of each stage is 10% -30%; and (3) preserving the heat of a thallus culture solution obtained by multistage amplification culture at 65 ℃ for 2 hours to break cells, releasing substances such as lentinan, polypeptide, protein, enzyme, quinones and the like in the cells, performing coarse filtration by using a 100-mesh filter screen and fine filtration by using a 300-mesh filter screen, adding a small amount of honey according to needs to adjust the taste, sterilizing, and filling into a 100-milliliter bottle to obtain a lentinan beverage finished product.
Wherein,
the rejuvenation culture medium comprises the following components: 30 g of corn flour, wheat flour, millet flour or buckwheat flour, 20 g of cane sugar, 20 g of wheat bran, 20 g of rice bran, 3 g of monopotassium phosphate, 3 g of dipotassium phosphate, 1.5 g of magnesium sulfate, 3 g of yeast extract and 30 g of agar, adding 1000 ml of water, uniformly mixing, heating to dissolve, cooling to solidify, and sterilizing for 30 minutes at 121 ℃.
The formula of the liquid culture medium is as follows: 30 g of corn flour, 20 g of cane sugar, 20 g of wheat bran, 20 g of rice bran, 3 g of monopotassium phosphate, 3 g of dipotassium phosphate, 1.5 g of magnesium sulfate and 3 g of yeast extract, adding 1000 ml of water, uniformly mixing, and sterilizing for 30 minutes at 121 ℃.
The method of the invention is characterized in that:
A. rejuvenating strains are alternately used by the starch components of the culture medium, such as millet, corn, buckwheat, wheat and the like, so that the problems of fast strain degeneration and product quality reduction are solved; the mushroom fungus is degraded quickly in the culture process, seriously affects the quality of products and is difficult to continuously produce. By using a plurality of culture mediums alternately, the problem of product quality reduction caused by strain degeneration is solved by using a rejuvenation method, so that the strain with stronger activity is used every time, and the product quality is ensured.
The strain is preserved for a long time, the strain is used for a long time and the number of times of tube transfer is too many, so the strain rejuvenation work is required, and the rejuvenation method comprises the following steps: separating and purifying, activating and transplanting, replacing culture medium, and changing culture medium with different formula can enhance new vitality and promote good seed rejuvenation. The strain is from a strain purchased by mushroom farmers from the fungus institute of Sanming City, the strain with good growth vigor is taken from the mushroom farmers, the mushroom strain is inoculated into different (corn, buckwheat, millet and wheat) solid rejuvenation culture mediums for culture, each culture medium is cultured for about 20 days, the strain with good growth vigor is screened for seed preservation and production, and the strain with good growth vigor is inoculated into a liquid culture medium sterilized at 121 ℃ for 30 minutes for multistage amplification culture. The sequence and frequency of use of the rejuvenation media of various types are not limited. For example, in this embodiment, mushroom strains are first cultured in a maize rejuvenation medium for 20 days, strains with good growth vigor are selected and transplanted into a wheat rejuvenation medium for 20 days, strains with good growth vigor are selected and transplanted into a millet rejuvenation medium for 20 days, and strains with good growth vigor are selected and transplanted into a buckwheat rejuvenation medium for 20 days to achieve the purpose of rejuvenation.
B. The formula of the liquid culture medium is as follows: 30 g of corn flour, 20 g of cane sugar, 20 g of wheat bran, 20 g of rice bran, 3 g of monopotassium phosphate, 3 g of dipotassium phosphate, 1.5 g of magnesium sulfate, 3 g of yeast extract and 1000 ml of water. The formula of the liquid culture medium is obtained by comprehensively adjusting the dosage and combination of starch, sugar, potassium and magnesium ions, vitamins, wheat bran, rice bran and other components on the basis of the solid culture medium in the prior art. (the formulation screening protocol is shown in attached table 1 and 2)
In the tests, when more than 30 grams of corn flour were used in the formula, the corn flour medium was not used up, whereas less than 30 grams of corn flour had less edible fungal mass in the culture broth, and the culture medium was not as required for different culture times, 30 grams of corn flour per liter being selected in the formula of the invention.
The results of tests on the amounts of sucrose, glucose, wheat bran, potassium phosphate, etc. shown in the attached Table 1 are: the edible fungi cultured by the sucrose and the glucose have little difference in results, and the cost of the sucrose is lower; the wheat bran has a higher utilization rate of 20 grams per liter; the dosage of the potassium dihydrogen phosphate and the dipotassium hydrogen phosphate has certain influence on the quantity and the size of the thalli.
Table 2 attached hereto, in order to solve the influence of the potassium dihydrogen phosphate and the dipotassium hydrogen phosphate on the edible fungus mass, the present invention has further experiments, and the experimental results show that the amount of the dipotassium hydrogen phosphate affects the growth of the edible fungus mass, and when the amount of the dipotassium hydrogen phosphate is large, the edible fungus mass is small and large, so that in the production, when a large number of breeding generations are needed, the edible fungus mass can be adjusted by adjusting the amount of the potassium. Conversely, the amount of dipotassium phosphate can be reduced when smaller edible fungus clusters are required. The test shows that 3 g of potassium dihydrogen phosphate and 3 g of dipotassium hydrogen phosphate are used per liter.
Attached table 1: one of the culture medium formulation screens
Attached table 2: comparison of the amounts of Potassium dihydrogen phosphate, dipotassium Hydrogen phosphate and wheat bran
The wheat bran and the rice bran are added into the liquid culture medium, so that the quality of the product is improved; when a producer cultures mushroom strains, a PDA culture medium (200 g of potatoes, 20 g of glucose, 20 g of agar and 1000 ml of water) is mostly adopted; PSA medium (potato 200 g, sucrose 20 g, agar 20 g, water 1000 ml); the culture of the mother strain of shiitake mushroom (authored by Zhang Bao Jun from Shii Xiang Mushroom culture Utility technology) was carried out in a CPDA medium (potato 200 g, glucose 20 g, agar 20 g, potassium dihydrogen phosphate 2 g, magnesium sulfate 0.5 g, and water 1000 ml) or the like, but the liquid medium was prepared in the above formulation without adding agar. The shiitake liquid culture medium in the 'mushroom production technology book' compiled by Chen Shi Yu has five formulas: 1. wheat bran 5%, glucose 2%, ammonium sulfate 0.1%, magnesium sulfate 0.04%, zinc sulfate 0.02%, boric acid 0.01%, gypsum powder 1%, vitamin B121 ml, agar 0.05%, and natural pH; 2. 20% of potato, 2% of glucose, 0.2% of ammonium sulfate, 0.1% of monopotassium phosphate, 0.05% of magnesium sulfate, 110 mg/1L of vitamin B, 0.05% of agar and natural pH; 3. 7-9% of soluble starch, 1% of glucose, 1.5-2% of corn steep liquor, 0.1% of monopotassium phosphate and 9 mg/L of zinc sulfate; 4. 90% of citric acid fermentation wastewater (containing 1.5% of sugar), 8% of wheat bran leachate, 1% of sweet potato powder and pH 6.5; 5. 3% of sucrose, 0.1% of monopotassium phosphate, 0.1% of magnesium sulfate, 5% of wheat bran leachate, 0.3% of corn steep liquor and pH 6.5. Some mushroom farmers add rice bran and wheat bran into the solid culture medium, the operation is troublesome, the pollution is easy, the drinking taste is influenced, and no rice bran component is added into the formula of the liquid culture medium. The wheat bran and rice bran which are difficult to eat and absorb for human are effectively absorbed and transformed by edible fungi and then are supplied to human for eating (see attached table 3 and attached drawing).
An accessory 3: one of multiple comparative experiments with wheat bran and rice bran
Note: as can be seen from the figure, the culture medium has the same components, and the growth vigor of the strain added with the wheat bran and the rice bran is better than that of the strain added with VB1 compared with that of the control without the wheat bran, and the growth vigor of the strain added with the wheat bran is slightly worse than that of the culture solution added with the rice bran solution.
C. Multi-stage amplification is carried out in a shorter time, so that the production cost is reduced; because the production link needs to carry out multi-stage amplification on strains, each stage of growth cycle of the strains needs a certain time, and each batch of products needs more than two months from inoculation to liquid culture medium to becoming products, the production time of the products is long, and the cost is high. The invention explores a method for simultaneously carrying out amplification culture of a plurality of levels in a plurality of stages, namely taking out strains from a rejuvenated solid culture medium and inoculating the strains into 50 ml of liquid culture medium, inoculating 50 ml of cultured liquid strains into 250 ml of liquid culture medium, inoculating 250 ml of liquid strains into 500 ml of liquid culture medium, and inoculating 500 ml of liquid strains into 1500 ml of liquid culture medium. The inoculation amount of each level is about 10-30% (namely after the strain product obtained by each level of cultivation is collected, 10-30% (mass percentage) of the strain product is inoculated into the next level of culture medium for next level of cultivation), and each level of cultivation is performed in a shaking table at 25 ℃ for 7 days. Four-stage culture is carried out simultaneously by a plurality of culture boxes or one culture box, so that the biological activity of the strain is ensured, the production time is shortened, and the production cost is reduced.
D. The cells are broken after the temperature is kept at 65 ℃ for hours, and the extraction is carried out, so that the product can keep the biological activity of the effective components to a greater extent; most producers use a high-temperature method to break cells and release substances in the cells, but the high temperature can cause the loss or reduction of the activity of active ingredients in the mushroom culture solution, such as enzyme, polysaccharide, polypeptide and protein, and the degradation of the active ingredients of the mushrooms, so that the products cannot play the best role.
