Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine food and beverage technology, specifically to a green brick raspberry sweet black tea beverage with nourishing and strengthening properties and its preparation method. Background Technology

[0002] Green brick tea is an important category of dark tea in my country, belonging to the category of deeply fermented tea. It is mainly produced in the southern Hubei tea region, with Xianning City in Hubei Province being one of the main production areas, and Yangloudong in Chibi being its key origin. With the increasing awareness of health, the health benefits of green brick tea, such as regulating the intestines, weight loss, lowering lipids, antibacterial properties, and antioxidant effects, are gradually gaining attention.

[0003] However, green brick tea is cold in nature, and when used alone, it is insufficient in terms of nourishing the body's vital energy and strengthening its foundation. Furthermore, there is a lack of effective formulas that can be combined with other ingredients to specifically enhance the body's nourishing and strengthening effects.

[0004] Based on this, the present invention uses Chibi green brick tea as a base and combines it with raspberry leaves to make green brick raspberry sweet black tea, utilizing the characteristics of raspberry leaves to optimize the base tea body; then it is compounded with astragalus, wolfberry, hawthorn and dried tangerine peel to create a green brick raspberry sweet black tea beverage with the effect of nourishing the body and strengthening the foundation. Summary of the Invention

[0005] To address the shortcomings of the existing technologies, this invention provides a sweet black tea beverage made from green brick tea and raspberry leaves, along with its preparation method. This invention uses Chibi green brick tea and raspberry leaves as the main ingredients, supplemented with astragalus and wolfberry, and further enhanced with dried tangerine peel and hawthorn to replenish qi, thus preparing a sweet black tea beverage made from green brick tea and raspberry leaves that nourishes the body, strengthens the body, and regulates intestinal function.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0007] This invention provides a sweet black tea beverage made from Chibi green brick tea and raspberry, which has the effect of nourishing the body's vital energy and strengthening its foundation. The ingredients, by weight, include: 65-75 parts Chibi green brick tea, 20-35 parts raspberry leaves, 3-5 parts astragalus, 3-5 parts goji berries, 3-5 parts hawthorn, and 3-5 parts dried tangerine peel. The 65-75 parts of Chibi green brick tea form the core, regulating intestinal flora, lowering lipids and blood sugar, and laying the foundation for basic conditioning effects. The 20-35 parts of raspberry leaves assist in warming and nourishing the spleen and stomach, improving the cold nature of green brick tea, and synergistically optimizing the intestinal conditioning effect. Astragalus replenishes qi and raises yang, strengthens the body's resistance, and stops sweating; goji berries nourish the liver and kidneys, benefit essence and improve eyesight. Combined with astragalus, they achieve simultaneous replenishment of qi, blood, and essence, solidifying the material basis for nourishing the body's vital energy and strengthening its foundation. Hawthorn aids digestion, strengthens the stomach, invigorates blood circulation, and promotes the function of the spleen and stomach, preventing "supplementation without stagnation." Tangerine peel regulates qi, strengthens the spleen, dries dampness, and resolves phlegm, thus regulating the qi mechanism of the spleen and stomach and helping the nourishing ingredients to exert their effects. At the same time, it harmonizes all the flavors. Only 3-5 portions are needed to achieve their supplementary effects.

[0008] To address the shortcomings of existing green brick teas in terms of their cooling properties and insufficient nourishing and strengthening effects, this invention provides a green brick raspberry sweet black tea beverage with nourishing and strengthening properties. This beverage primarily uses Chibi green brick tea and raspberry leaves, supplemented with astragalus and goji berries, and further enhanced with dried tangerine peel and hawthorn to replenish qi. Chibi green brick tea regulates intestinal flora and lowers lipids and blood sugar, laying the foundation for the beverage's conditioning effects. When combined with raspberry leaves to create a sweet black tea, it retains its original effects while mitigating the cooling properties of the green brick tea. Raspberry leaves are sweet and slightly bitter, with a slightly warm nature, rich in various nutrients and active substances. They can assist in warming and nourishing the spleen and stomach, providing a basic physiological environment for nourishing and strengthening the body. They also work synergistically with green brick tea to optimize intestinal conditioning effects and give the tea a unique flavor. Flavor profile: Astragalus is sweet and slightly warm in nature, entering the lung and spleen meridians. It excels at tonifying qi and raising yang, consolidating the exterior and stopping sweating. It can strengthen the body's vital energy and replenish primordial qi, making it a core medicinal material for nourishing the body's foundation and helping to improve the function of the internal organs and enhance immunity. Goji berries are sweet and neutral in nature, entering the liver and kidney meridians. They can nourish the liver and kidneys, benefit essence and improve eyesight, replenish kidney essence, and nourish the internal organs. When combined with astragalus, they can replenish qi, blood, and essence simultaneously, solidifying the material foundation for nourishing the body's foundation. Hawthorn can aid digestion, strengthen the stomach, and promote blood circulation. It can promote the digestion of the spleen and stomach, allowing for better absorption of nutrients and helping to "nourish without stagnation" during the process of nourishing the body's foundation, maintaining the body's metabolic balance. Dried tangerine peel can regulate qi and strengthen the spleen, dry dampness and resolve phlegm, and regulate the flow of qi. It can help the spleen and stomach qi flow smoothly, allowing the nourishing components such as astragalus and goji berries to play a better role, synergistically enhancing the effects of nourishing the body's foundation and also harmonizing the flavors and optimizing the taste of the beverage. The medicinal materials in this invention complement each other, preserving the unique advantages of Chibi green brick tea while strengthening its nourishing and strengthening effects, improving the tea's cold nature and taste, enriching the product forms of green brick tea, and also helping to promote local characteristics and drive innovation and upgrading of the tea industry and the traditional Chinese medicine food and beverage industry.

[0009] Furthermore, the raw materials of the green brick raspberry sweet black tea beverage include, by weight: 65 parts of Chibi green brick tea, 20 parts of raspberry leaves, 5 parts of hawthorn, 5 parts of astragalus, 5 parts of dried tangerine peel, and 5 parts of goji berries.

[0010] Furthermore, the raw materials of the green brick raspberry sweet black tea beverage include, by weight: 71 parts of Chibi green brick tea, 15 parts of raspberry leaves, 4 parts of hawthorn, 4 parts of astragalus, 4 parts of dried tangerine peel, and 4 parts of goji berries.

[0011] Furthermore, the raw materials of the green brick raspberry sweet black tea beverage include, by weight: 75 parts of Chibi green brick tea, 10 parts of raspberry leaves, 3 parts of hawthorn, 3 parts of astragalus, 3 parts of dried tangerine peel, and 3 parts of goji berries.

[0012] Furthermore, the Chibi green brick tea mentioned above is made from Chibi green brick tea that has been stored for 7 years.

[0013] Furthermore, the active ingredients of the astragalus, wolfberry, hawthorn and tangerine peel were extracted using an alkaline electrolysis water extraction method.

[0014] This invention also provides a method for preparing the aforementioned green brick raspberry sweet black tea beverage with nourishing and strengthening properties, comprising the following steps:

[0015] S1. Dry Awakening of Chibi Green Brick Tea: After placing the Chibi green brick tea in a dry and ventilated place for 5-7 days, it is then stored in a ceramic jar for about 2 months for later use. This invention uses Chibi green brick tea that has been stored for 7 years. Since Chibi green brick tea is a compressed tea, after long-term storage, it needs to be dry-awakened to remove impurities and awaken its mellow aroma. In specific operation, first use a tea knife to insert from the side of the tea brick and gently shake and pry it off, trying to keep the tea leaves as intact as possible and avoid excessive breakage. Then place the pried-off tea leaves in a dry and ventilated place for 5-7 days to allow impurities to fully dissipate. Finally, seal the breathable tea leaves in a well-ventilated ceramic jar and store it for about 2 months, allowing the tea leaves to naturally transform in a stable environment, releasing a fuller and more mellow flavor for subsequent drinking.

[0016] S2. Wet awakening and brewing of Chibi green brick tea: Put the dried Chibi green brick tea into a purple clay teapot, add boiling water, wait for 0.5-1 minute, and pour out the boiling water to complete the wet awakening; add boiling water and brew the wet awakened Chibi green brick tea using the high-pouring method to obtain green brick tea soup.

[0017] S3. Fermentation of raspberry leaves: Fresh raspberry leaves are subjected to high-temperature blanching, kneading, and fermentation to obtain fermented raspberry leaves.

[0018] S4. Preparation of Green Brick Raspberry Sweet Black Tea: After mixing the green brick tea soup prepared in step S2 with the fermented raspberry leaves prepared in step S3, steam treatment is carried out in a high-temperature steam environment of 100-120 ℃. Under the continuous action of steam, the two materials are fully integrated, and the aroma and flavor of the green brick tea and fermented raspberry leaves permeate each other, and the physical structure also changes, finally forming a unique flavor of green brick raspberry sweet black tea, which has both the mellowness of Chibi green brick tea and the sweet aroma of fermented raspberry leaves, with a rich taste.

[0019] Preparation of S5 extracts of Astragalus membranaceus, Lycium barbarum, Crataegus pinnatifida, and Citrus reticulata: Astragalus membranaceus, Lycium barbarum, Crataegus pinnatifida, and Citrus reticulata are mixed and pulverized according to a predetermined ratio to obtain a pulverized mixture; the pulverized mixture is mixed with alkaline electrolyzed water, and extracted at 60℃ for 40-60 minutes using the alkaline electrolyzed water extraction method, and then filtered to obtain the extract.

[0020] S6. Preparation of Green Brick Raspberry Sweet Black Tea Beverage: Mix the green brick raspberry sweet black tea prepared in step S4 with the extract prepared in step S5 to obtain a mixed liquid.

[0021] S7. Processing and Packaging of Finished Products: The mixture prepared in step S6 is sterilized using ultra-high temperature instantaneous sterilization. The sterilized mixture is then packaged to obtain a green brick raspberry sweet black tea beverage with nourishing and strengthening properties.

[0022] Further, the specific operation of step S2 is as follows: Put the prepared Chibi green brick tea from step S1 into a Zisha teapot, start boiling water, and heat it rapidly over high heat. When the water continues to boil to the second boil, immediately pour the boiling water into the Zisha teapot containing the tea leaves, wait for 30 seconds to 1 minute, and wait for the green brick tea leaves to gradually unfurl. Then, quickly pour out the tea soup to complete the tea awakening process. Next, boil the water again to the second boil, and use a high pouring method to brew the awakened tea leaves, allowing the water flow to fully agitate the tea leaves. After steeping for 8-10 minutes, you will obtain a green brick tea soup with a rich aroma and mellow taste.

[0023] Further, the specific operation of step S3 is as follows: Fresh raspberry leaves are put into a high-temperature fixation device and fixed at 180-250℃ for 1-3 minutes. The high temperature destroys the activity of oxidases in the leaves, terminates the tea fermentation process, and locks in natural nutrients. After fixation, the leaves are rolled to break the leaf tissue and release cell sap, laying the foundation for subsequent fermentation. The rolled raspberry leaves are piled up for fermentation in a constant temperature environment of 40-50℃. During this stage, the leaves need to be piled up to a certain thickness. Through the action of microorganisms and the humid and hot conditions, a series of complex changes are induced, which last for 5-8 days until the color, aroma, and taste of the leaves reach the ideal state, and finally fermented raspberry leaves are obtained.

[0024] Further, in step S4, the weight ratio of the green brick tea soup to the fermented raspberry leaves is (2.5-3.5):1.

[0025] Furthermore, in step S5, the pulverization is carried out in a pulverizer, with the pulverization speed set to 250-300 rpm, and the pulverization is continued for 8-12 minutes.

[0026] Further, in step S5, the weight ratio of the pulverized mixture to the alkaline electrolyzed water is 1:(4-6).

[0027] Further, in step S6, the volume ratio of the green brick raspberry sweet black tea to the extract is (14-16):1.

[0028] Furthermore, in step S7, the ultra-high temperature instantaneous sterilization is performed at 135-140 ℃ for 3-5 seconds.

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] This invention uses Chibi green brick tea and raspberry leaves as the main ingredients, supplemented with astragalus, wolfberry, and tangerine peel and hawthorn to replenish qi, to prepare a green brick raspberry sweet black tea beverage with the function of nourishing the body's vital energy and strengthening the foundation. Chibi green brick tea has the effects of regulating intestinal flora and assisting in lowering blood lipids and blood sugar. However, it is slightly cold in nature. In order to harmonize its nature and enhance its effects, this invention cleverly incorporates warm medicinal materials into the beverage formula. Among them, hawthorn is rich in organic acids, which are effective components for promoting digestion and relieving stagnation. Its flavonoids are also active substances for preventing and treating cardiovascular diseases and lowering blood lipids. Tangerine peel is pungent and bitter, and warm in nature. It is good at regulating qi, stimulating appetite, drying dampness and resolving phlegm. It is an essential medicine for regulating the spleen and stomach. Astragalus replenishes qi and strengthens the exterior, while wolfberry nourishes the liver and kidneys, benefits essence and improves eyesight. Together, they have the effect of nourishing the body's vital energy and strengthening the foundation. In addition, raspberry leaves, with their traditional effects of strengthening essence and reducing urination, further strengthen the overall positioning of "strengthening the foundation". This invention features a uniquely crafted formula that allows the core nourishing and strengthening effects of green brick raspberry sweet black tea to be fully realized. The warming properties of hawthorn, dried tangerine peel, astragalus, goji berries, and raspberry leaves harmonize and complement the slightly cooling nature of the green brick tea, significantly improving the overall taste and effectively neutralizing its cooling properties, resulting in a more balanced beverage. Furthermore, this innovative product form combines local green brick tea with various medicinal and edible herbs, opening up new avenues for promoting Chibi's local specialties. The preparation process is particularly meticulous: First, the Chibi green brick tea undergoes professional dry and wet awakening treatments, allowing the compressed tea to fully unfurl, dissipate impurities, and release its rich flavor. A special technique is used to break the tea leaves into whole pieces, preserving the integrity of the tea leaves and stems to the greatest extent possible, ensuring no loss of its unique flavor and beneficial substances. The auxiliary ingredients—hawthorn, dried tangerine peel, astragalus, goji berries, and raspberry leaves—are fully extracted to obtain their essential components. Finally, ultra-high temperature instantaneous sterilization (UHT) technology is applied in a sterile environment to ensure safety while maximizing the preservation of the original flavor and activity of the green brick tea and herbal ingredients. After canning and packaging, the finished product is obtained. This preparation process chain is closely linked, aiming to create a healthy tea beverage that combines health benefits, local characteristics, and mellow flavor. Attached Figure Description

Wet awakening and brewing of Chibi green brick tea: Put the Chibi green brick tea processed in S1 into a purple clay teapot, start boiling water, heat it quickly over high heat, and when the water continues to boil to the second boil, immediately pour the boiling water into the purple clay teapot containing the tea leaves, wait for 30 seconds, and when the green brick tea leaves gradually unfurl, quickly pour out the tea soup to complete the awakening of the tea; then, boil the water again to the second boil, and use a high pouring method to brew the awakened tea leaves, allowing the water flow to fully agitate the tea leaves, and after steeping for 10 minutes, you will get a green brick tea soup with a rich aroma and mellow taste.

[0071] S3. Fermentation of Raspberry Leaves: Fresh raspberry leaves are placed in a high-temperature fixation device and fixed at 210 ℃ for two minutes. The high temperature destroys the activity of oxidases in the leaves, stopping the tea fermentation process and locking in natural nutrients. After fixation, the leaves are rolled, using external force to break the leaf tissue and release cell sap, laying the foundation for subsequent fermentation. The rolled raspberry leaves are then piled up for fermentation in a constant temperature environment of 50 ℃. During this stage, the leaves need to be piled up to a certain thickness. Through the action of microorganisms and the humid and hot conditions, a series of complex changes are induced, which last for 8 days until the color, aroma, and taste of the leaves reach the ideal state, and finally fermented raspberry leaves are obtained.

[0072] S4. Preparation of Green Brick Raspberry Sweet Black Tea: The green brick tea soup prepared in step S2 and the fermented raspberry leaves prepared in step S3 are mixed at a weight ratio of 3:1 and then steamed in a high-temperature steam environment at 120 ℃. Under the continuous action of steam, the two materials are fully integrated, and the aroma and flavor of the green brick tea and the fermented raspberry leaves permeate each other, and the physical structure also changes, finally forming a unique flavor of green brick raspberry sweet black tea, which has both the mellowness of Chibi green brick tea and the sweet aroma of fermented raspberry leaves, with a rich taste.

[0073] Preparation of S5 extracts of Astragalus membranaceus, Lycium barbarum, Crataegus pinnatifida, and Citrus reticulata: Astragalus membranaceus, Lycium barbarum, Crataegus pinnatifida, and Citrus reticulata were placed together in a grinder in a predetermined ratio, and the grinding speed was set to 300 rpm for 10 minutes to obtain a pulverized mixture. The pulverized mixture was then mixed with alkaline electrolyzed water at a weight ratio of 1:5, and extracted at 60 °C for 60 minutes using the alkaline electrolyzed water extraction method. The mixture was then filtered to obtain the extract.

[0074] S6. Preparation of green brick raspberry sweet black tea beverage: Mix the green brick raspberry sweet black tea prepared in step S4 with the extract prepared in step S5 at a volume ratio of 15:1 to obtain a mixed liquid.

[0075] S7. Processing and Packaging of Finished Products: The mixture obtained in step S6 is sterilized using ultra-high temperature instantaneous sterilization to obtain a sterilized mixture. The sterilized mixture is then packaged using canning packaging to obtain the finished beverage. The finished beverage is then tested, and after passing the test, it is packaged and stored in the warehouse, ultimately yielding a green brick raspberry sweet black tea beverage with the function of nourishing the body and strengthening the foundation.
