Description

Inonotus obliquus and angelica keiskei koidz leaf tea and preparation method thereof
The invention relates to a divisional application with the application number of 201710699726.2, the application date of 2017, 08 and 16 months and the invention name of 'a preparation process of inonotus obliquus and angelica keiskei koidzumi tea'.
Technical Field
The invention relates to the technical field of tea preparation, and particularly relates to inonotus obliquus and angelica keiskei koidzumi tea and a preparation method thereof.
Background
China is the world with tea making traders and the earliest tea drinking and health preserving countries, and tea leaves, like silk and ceramics, are the staple products of ancient times and world trade in China and are reputable to the world.
Angelica keiskei Koidz is a evergreen upright herb plant growing in Angelica of Apiaceae in Umbelliferae for many years. The plant has the phenomena of fast growth and strong vitality, and is named after the phenomena of leaf picking up in the present day and new bud growing in the tomorrow. The famous Li Shizhen of China early in compendium of materia Medica (1593 years) of China sets forth that the Mingriye, namely coastal angelica, has sweet and pungent taste and warm nature, and enters liver, heart and large intestine channels; in Japan, the contents of "Dahe and Ben Cao" (1709) and "compendium of redetermined Ben Cao" (1844) are recorded that the leaf of Angelica keiskei can strengthen the body, promote health and prolong life, so people advocate the leaf of Angelica keiskei as a curiosity plant and also as a longevity magic grass for the King Huang of Qin in the introduction. The current research of the angelica keiskei starts from 60 Japan in the 20 th century, is introduced into China in the 90 th century, is introduced to Shandong, Hainan and the like at present, and has been reported in recent years for producing health care products such as the angelica keiskei, capsules, decoction pieces and the like and foods such as noodles, desserts and the like. The angelica keiskei contains special nutritional ingredients which are safe, nontoxic, strong in activity, free of other plants such as chalcone and organic germanium or low in content, so that the angelica keiskei has special health-care functions of reducing blood sugar, protecting liver, resisting cancer, preventing cardiovascular and cerebrovascular diseases and the like, and is known as health food in the 21 st century.
The history of when the tomorrow leaves began to make tea was difficult to study. In the Angelica keiskei production areas such as the Kyoho, the vegetables are both wild and planted by residents, and are all eaten as daily vegetables. Until the institute of Dongyang medicinal herbs, that is, the research institute of medical doctor hou teng was conducted in 1968, in order to research the Chinese medicine, when eight husband islands buy poisonous snakes, a hotel was left, the owner had accidentally eaten the angelica keiskei cuisine personally made by the owner, and it was found that the angelica keiskei is very long-lived and healthy because people on the islands often eat the angelica keiskei, and the angelica keiskei also has strong vitality, thereby arousing the curiosity of the research of the owner. After the research and popularization of more than 20 years, the Chinese patent application is written as a book of 'experience talk on tomorrow leaves' in 1999, and the people know that the tomorrow leaves leave the island. At present, 20% of the products of the angelica keiskei are used for fresh vegetable supply, and about 80% of the angelica keiskei are processed into tea, powder and beverages and also used as other food additives.
Whether china has tomorrow leaves in ancient times? Is Binghai Dang Gui mentioned in Ben Cao gang mu of today's tomorrow? These problems are yet to be further examined. However, in the literature, the tomorrow leaf planted in China is introduced from Japan in nearly 20 years. The earliest reports were that planting bases were gradually formed in Hainan island from Japan in 2007, and that Angelica keiskei tea products were available. Then, the tomorrow leaf also forms a planting base in coastal areas such as Shandong sunshine, Qingdao and the like, wherein the planting scale of the sunshine synchrust agriculture science and technology development limited company exceeds 230 mu.
Therefore, the commercial development of the angelica keiskei koidzumi tea in the world is about 20 years, and the angelica keiskei koidzumi tea belongs to a novel medicinal and edible drink. Inonotus obliquus is also called Inonotus obliquus, and Ganoderma fuscous. The mycelium of the inonotus obliquus can resist low temperature of minus 40 ℃, and is mainly distributed in regions with north latitude of 45-50 degrees in northern hemisphere, such as Russia (West Siberian, the far east region, Chaocai), Finland, Poland, China (Heilongjiang river, Jilin Changbai mountain region), Japan (Hokkaido), and the like. Inonotus obliquus as one of special Ganoderma lucidum belongs to fruiting body of fungus of Polyporaceae. The application has a long history, and according to the record of the first Chinese monograph 'Shennong herbal Jing': the glossy ganoderma has six types of purple, red, green, yellow, white and black, and is recorded in compendium of materia medica, the glossy ganoderma has mild nature, bitter taste and no toxicity, is mainly used in chest to stop knot, benefits heart-qi, supplements middle-jiao, increases wisdom, is not forgotten, is light and not old after being taken for a long time, and prolongs the life of the immortal spirit. The use of Inonotus obliquus by Russia, Finland and Ukrainian folks also has a long history. In the 12 th century, Russian people used the decoction of wild birch mushroom to treat their diseases. Russian scientists have conducted intensive studies on the effective components of Fuscoporia obliqua and the therapeutic effects of Fuscoporia obliqua on diseases in 1949. The former soviet union ministry of health approved the application of inonotus obliquus preparation in 1955. The research on the Inonotus obliquus in China in recent times is rarely seen in documents and just starts.
Active substances such as polysaccharides and triterpenes contained in the Inonotus obliquus can improve immunity of human body, and has obvious health promotion effect. According to the introduction of scientific and technical literature, the inonotus obliquus has certain curative effects on reducing blood sugar, protecting liver, resisting cancer, preventing cancer and the like, and particularly has more remarkable effect on reducing blood sugar. And because each gram of the inonotus obliquus contains 35000 units of superoxide dismutase (SOD), which is 23 times of that of the agaricus blazei murill, 25 times of the hericium erinaceus, 31 times of the grifola frondosa and 55.6 times of that of the ganoderma sinense, the inonotus obliquus has excellent antioxidation and has the function of delaying senility after being taken for a long time.
The Inonotus obliquus grows on the birch of Russian and original deep forest of Siberian at the temperature of minus 45 ℃, the mycopolyose is more than or equal to 50 percent, the triterpenoid substance is more than or equal to 4.5 percent, and the quality is particularly good. Because of limited wild resources, the relatively high price is the defect of the Inonotus obliquus. The inonotus obliquus belongs to porous polysaccharide in structure, is easy to damp, mildew and deteriorate, and is one of the defects of food materials.
As a big country for researching and producing tea, China applies more than 14 thousands of patent inventions related to tea, and authorizes more than 1.8 thousands of patent inventions. Among them, 10 patent applications relating to the tea leaves of Angelica keiskei Koidz are disclosed, and the earliest patent application was found in "Angelica keiskei Koidz tea (200810171414.5)" filed by Takara Bio-engineering Co., Ltd in 2008, and the heating temperature of the roasting heating treatment is preferably 100-150 ℃, and the dried material of the Angelica keiskei Koidz to be subjected to the roasting heating is preferably a dried material having a moisture content of 20% or less obtained by dry drying treatment after preliminary steaming. The production process (200910144996.2) of angelica keiskei koidzumi, which is disclosed by the domestic company in 2009, mainly comprises the steps of picking fresh angelica keiskei koidzumi and washing with water, spreading and airing, deactivating enzymes, rolling, drying, rolling and frying, screening and drying to obtain the finished angelica keiskei koidzumi tea. 2013 has patent applications of "mixed tea of tomorrow leaves and ginkgo leaves (application number: 201310742788.9)" and "tomorrow leaf tea added with jasmine flowers (application number: 201310712527.2)"; in 2014, there is a patent application of "Mingriye fermented tea (application number: 201410345442. X)" which comprises the process steps of cleaning, spreading and airing and withering, warm bleaching, throwing water, cutting, withering by hot air, rolling, fermenting, drying by gross fire, spreading and cooling, drying by full fire, screening and the like. Proper exogenous enzyme is added in the rolling and fermenting processes to assist the fermentation of the angelica keiskei. The angelica keiskei fermented tea prepared by the process obviously improves the astringent taste of the angelica keiskei tea product, is mellow and pleasant after being brewed, has mellow and thick taste and sweet aftertaste, and simultaneously improves the main qualities such as tea polyphenol content, total flavone content, polysaccharide content, free amino acid content and the like.
The process for preparing the angelica keiskei koidzumi tea in the prior art mainly solves the characteristic that the tea is suitable for drinking, pays attention to the appearance and the taste of the tea, uses a steaming-drying process for preparing the tea by using tea leaves or a manual process for stir-frying and scattering the tea, and has the advantages of high labor intensity, low production efficiency, difficult process standardization and difficult maintenance of pure green tea. On the other hand, the angelica keiskei koidzumi is taken as medicinal tea, the main medicinal components of the angelica keiskei koidzumi are chalcone, organic germanium and active calcium, and the components belong to organic matters and metal organic matters, and have small water solubility, so that the angelica keiskei koidzumi prepared by the original process is difficult to dissolve out even being brewed by boiling water, thereby not only wasting the precious medicinal components, but also greatly reducing the health-care effect. The prior enzyme technology needs long-time spreading and drying in the air, not only is the labor intensity large and the efficiency low due to repeated pile turning, but also the leaf turns yellow and loses green due to the catalytic oxidation reaction of the proenzyme in the angelica keiskei during the pile-up, the quality of the green tea is reduced, and only fermented tea (black tea) can be prepared. The raw material needs old leaves of more than 1 month, single enzyme has little hydrolysis to vascular bundles of angelica keiskei which is composed of pectin layer, cellulose and hemilignin, can not effectively increase the dissolution of chalcone and organic germanium, but generates tea polyphenol with excitation function.

In the technical scheme, in the step of opening the bone by freezing, the freezing not only inactivates biological enzymes in leaves and keeps the stability of active ingredients such as chalcone, but also freezes and expands water in cells and veins to loosen tissues, thereby creating conditions for dissolving out the chalcone. Experiments prove that the dissolution rate of chalcone is improved by 17-21% compared with the direct tea making process by the frozen angelica keiskei koidz tea; the step of soaking in ice to protect green, the water temperature is below 16 ℃, not only the dissolution of chalcone is reduced, but also small molecules such as oxalic acid which generates astringent taste can be dissolved out, and the frozen pore-formed angelica keiskei koidz is poured into mountain spring water to be iced, so that the chlorophyll can be prevented from being oxidized, the natural green can be kept, and the remarkable color protection effect is achieved; the angelica keiskei koidzumi is directly poured into tap water, the leaves are quickly oxidized by disinfectants such as chlorine and the like in the tap water, the green color is changed into yellow brown, and chalcone is oxidized, so that the quality of the tea is greatly reduced.
In the step of dewatering and moisture fixation, when the surface of the leaf of the angelica keiskei adsorbs water with the water content less than or equal to 2% and does not drip, the enzyme agent is easily and uniformly coated, the enzyme agent does not run off, and the enzyme agent can exert the maximum efficiency. When the adsorbed water is more than 2%, effusion is easily generated in equipment, the enzyme agent runs off, the enzyme agent on the surface of the angelica keiskei leaves is uneven, the concentration cannot be guaranteed, and the enzyme treatment effect is poor.
In the step of spraying enzyme and opening chains, the compound enzyme agent can effectively open the pectin layer of angelica keiskei leaves coated with chalcone, part of the pectin layer can damage cell walls, the pectin network taking calcium ions as chain points is opened, and when the angelica keiskei leaves are brewed by water with the temperature of more than 85 ℃, the dissolution amount of the chalcone, organic germanium, active calcium and other nutrient components can be effectively increased. Wherein, the dissolution amount of the chalcone of the angelica keiskei koidzumi tea subjected to 'frozen bone opening' and 'enzyme spraying chain opening' is increased by 2-3 times compared with that of the chalcone directly prepared, thereby effectively utilizing precious chalcone resources and obviously increasing the health care function of the chalcone.
In the above technical solution, when the angelica keiskei koidz is brewed with water, the technical difficulty of chalcone dissolution is that the chalcone dissolution amount cannot reach 30% of the actual content even if the water temperature reaches 100 ℃. The reason is for three aspects: (1) the leaf surface of angelica keiskei is provided with a waxy pectin waterproof functional layer, a pectic macromolecular chain is chelated by calcium ions to form a net-shaped protective layer, chalcone, organic germanium, active calcium and other nutrient components in the leaf are all coated by the pectin waterproof functional layer, and the chalcone dissolution rate is very low due to the non-hydrophilic property of the pectin waterproof functional layer; (2) the angelica keiskei leaves mainly comprise pectin layers, cellulose, hemilignin, water and the like, and nutrient components of cell sap such as chalcone, chlorophyll and the like are stored in cell walls containing the nutrient components, so that the structure is compact, and the dissolution rate of the nutrient components such as chalcone and the like is low; (3) chalcone is a derivative containing a specific structure of diphenylketene, and although a benzene ring contains a hydroxyl group, the chalcone has a large molecular weight, a small polarity and poor water solubility. Therefore, although the angelica keiskei koidzumi is a natural medicine-food dual-purpose plant with the highest chalcone content, the dissolution amount of the active ingredient chalcone cannot exceed 30% of the actual content of the angelica keiskei koidzumi when the angelica keiskei koidzumi is directly used for preparing tea due to the restriction of the three aspects, so that the waste of precious resources is caused, and the health-care effect is not good.
Aiming at the reasons, the invention adopts the 'freezing bone opening' process to freeze and expand the water in the vascular bundle, so that the leaf structure becomes loose, and the chalcone dissolution rate is improved by 17-21% compared with the direct tea making by using angelica keiskei leaves, and can reach about 45%. Meanwhile, the loose structure is also beneficial to the enzyme hydrolysis reaction in the next process. Through the 'enzyme spraying and chain opening' process, part of pectic substances and cellulose macromolecular chains are selectively hydrolyzed by the enzyme, the reticular protective layer of the leaf is partially destroyed, water molecules can more easily infiltrate into leaf cells and chalcone molecules thereof, when the water temperature reaches or exceeds 85 ℃, the dissolution rate of the chalcone can reach or exceed 95 percent of the actual content, and the precious medicinal resource is effectively utilized. Meanwhile, another special health-care component in the angelica keiskei, namely organic germanium, is also like chalcone, so that the dissolution rate is remarkably improved, and the health-care effect is improved.
The hydrolysis of the pectin mesh protective layer formed by calcium ion chelation increases the dissolution rate of calcium ions, and the natural biological calcium from the angelica keiskei is more beneficial to absorption and calcium supplement of human bodies.
Compared with the traditional process of adding an alkali agent sodium carbonate and carrying out enzyme inactivation at a temperature of 80 ℃, the 200-220 ℃ cylinder type continuous high-temperature inactivation process only needs 7s, has short time, does not cause the pollution of the alkali agent sodium carbonate, avoids the water washing process and avoids the loss of chalcone. Meanwhile, the second high-temperature technology also saves a large amount of time and secondary pollution problems required by airing and the problem that tedding occupies a large area. The second high temperature technology can also effectively avoid the defect of uncomfortable mouthfeel caused by drinking caused by the oxidation of burnt tea, chalcone and burnt smell.
In the technical scheme, the technical effects directly brought by the rolling modeling, the drying and shaping and the baking and aroma raising are that the obtained product is transferred to a rotary baking machine with inner blades for drying and shaping at the temperature of 130 ℃ and 140 ℃ after the rolling modeling. Further optimizing, raising the temperature of the rotary baking machine with the inner blades to 155-.
In the technical scheme, the unique technical effects of cooling and aging and secondary baking to produce fragrance are that the angelica keiskei is contacted with oxygen and moisture through cooling in the air, so that fragrance components are wetted, diffused and condensed on the leaves, and the leaves are stretched. Then the mixture is baked and fried at high temperature of about 10 ℃ to 165-170 ℃ for a short time (2-3min), thereby not only avoiding the defects of high-temperature scorching and throat pricking due to scorching in the primary frying process, but also baking out the aroma components with larger molecular weight, and leading the aroma to be stronger. Meanwhile, the transient high temperature also avoids the structural change of the chalcone at the high temperature, and the activity of the chalcone is kept.
It should be further noted that in the above technical scheme, after the processes of "baking and frying to extract fragrance" and "baking and producing fragrance for the second time" are carried out, although the disadvantages that the leaf tea burnt gas is pungent in throat and the taste is uncomfortable to drink due to the fact that the temperature is too high in the primary high-temperature baking and frying process are overcome, the problems of uneven heating of the tea leaves in the furnace, uneven quality, uneven fragrance and unreliably exist. In order to overcome the defect, the invention adds the process engineering of cooling large package and aging for 3-7 days, thereby well solving the problem.
In the technical scheme, the unique technical effect of the dried inonotus obliquus blending is that the influence of the addition of the dried inonotus obliquus on the essential fragrance and medicinal active ingredients of the inonotus obliquus in the previous period is avoided, and the fragrance can be generated through secondary baking in the next process, wherein the temperature is 165-170 ℃, the short-time heating is mixed with the fragrance of the angelica keiskei, and the mixture is integrated. And through the last procedure of aging and homogenizing fragrance, the fragrance of the antler and the tea slowly moistens the angelica keiskei, so that the fragrance of the angelica keiskei is better modified and strengthened, and the sensory feel is better. On the other hand, the Inonotus obliquus kills microorganisms after being subjected to high temperature of 165-170 ℃ for a short time, and overcomes the defect of easy mildew.
As a preferable scheme of the invention, in the step a, tomorrow leaves which are planted in coastal areas and irrigated with mountain spring water at 6-10 days after the spray irrigation are selected, and leaves with a long-term growth period of 5-10 days are selected.
The angelica keiskei is ancient called as coastal angelica, and as the name suggests, the angelica keiskei is suitable for growing in coastal areas with humid climate and cool temperature, only the angelica keiskei planted in the coastal areas is a genuine product, and the quality of the organic angelica keiskei of chemical fertilizers and pesticides can be effectively ensured by irrigating with mountain spring water. Therefore, the invention only selectively adopts the fresh organic angelica keiskei leaves which are planted in coastal areas, irrigated by spring water and have 15 to 29 days of new leaf growth period as the tea making raw materials;
spray-irrigating tomorrow leaf on the same day, and picking at 6-10 days next time. Through a large number of experimental analyses, the sprinkling irrigation not only washes away dust on leaves, avoids washing procedures and saves water, but also reaches a peak of chalcone content by 6-10 days after the growth in a wet environment at night (see table 1).

Content of chalcone 1270 1680 1660 1430 1220 1260 1350 1280
When the angelica keiskei leaves are picked, 0.5-1cm leaf stalks are reserved, so that the angelica keiskei leaves are convenient to pick, the leaves are not easy to break, chalcone in the leaves is not easy to lose, and the folium keiskei leaves are beneficial to twisting shaping to obtain uniform tea shapes.
In another preferred embodiment of the present invention, in step e, the food grade enzymatic agents are pectinase and cellulase.
Preferably, in the step f, the dried leaves of the angelica keiskei 5-7s pass through a 200-220 ℃ barrel type continuous enzyme deactivating machine.
