Description

Technical Field

[0001] The present invention relates to the technical field of tea processing technology, and more particularly to a process for processing purple juan tea into fuzhuan tea containing Eurotium cristatum. This process uses the unique Yunnan purple juan tea as raw material and, through a series of sophisticated processing steps, transforms it into fuzhuan tea containing the precious Eurotium cristatum fungus (commonly known as "golden flower"). This tea not only retains the unique flavor and nutritional value of the purple juan tea itself, but also introduces the Eurotium cristatum fungus through a special fermentation and cultivation process, thereby further enhancing the tea's health benefits and quality. Background Art

[0002] Traditional processing methods for Zijuan tea often overlook its potential health benefits, simply turning it into a standard tea product. Eurotium cristatum, also known as "golden flower," is a beneficial probiotic found in traditional Fuzhuan tea. It not only enhances the tea's taste and aroma but, more importantly, possesses significant health benefits, such as regulating intestinal flora and boosting immunity. Therefore, combining Zijuan tea with Eurotium cristatum to develop a novel tea product undoubtedly holds broad market potential and enormous commercial value. Summary of the Invention

[0003] In view of this, the present invention proposes a process for processing Zijuan tea into Fuzhuan tea containing Eurotium cristatum, and the specific technical scheme is as follows:

[0004] The process of processing Zijuan tea into Fuzhuan tea containing Eurotium cristatum comprises the following steps:

[0005] S1, raw material preparation, using Yunnan Zijuan tea sun-dried raw tea as raw material;

[0006] S2, in sequence, the tea is piled up, steam pressed into shape, blossomed, dried, and finished, or broken up and pressed into three-layer eight-petal lotus-shaped 5-gram cakes, and the finished products are packaged.

[0007] Furthermore, in step S1, the processing raw material is selected as the Zijuan tea with good quality that has been tested and qualified. The processing raw material Zijuan tea is prepared or mixed according to the quality grade of the tea, or the product is made by adding the tea from the ancient tree in proportion.

[0008] Furthermore, in step S2, the pile is steamed, and the steaming is completed in a tea steamer. The Zijuan tea is steamed for about five minutes, and the steam temperature is 98°C-102°C. After steaming, the pile is piled into a cone shape with a height of 2-3 meters. The pile time is 3-4 hours, and the height is slightly shorter for young bud Zijuan tea. During the pile-up process, the temperature in the Zijuan tea pile is 75°C-88°C. When the temperature is high, pay attention to timely heat dissipation. The Zijuan tea blanks are dug out layer by layer, and the stacking height does not exceed 1.5 meters. After heat dissipation, the temperature of the Zijuan tea blank drops to 45°C-58°C. Pay attention to dryness, wetness, coldness and heat, and maintain the purple color of the Zijuan tea.

[0009] Furthermore, in the step S2, during pressing and shaping, before flowering, the Zijuan tea base is added with Zijuan tea juice to improve the adhesion and humidity. The moisture content of the Zijuan tea base is controlled to be 25%-28%, which is low in spring and summer and high in autumn and winter according to the seasonal weather. After adding the Zijuan tea juice, the Zijuan tea pile is evenly spread to make the Zijuan tea juice and the Zijuan tea semi-finished product evenly mixed to maintain a uniform moisture content; the boiling ratio of the Zijuan tea juice is: one pound of Zijuan tea, twenty pounds of water, and after adding an appropriate amount of Zijuan tea juice, the Zijuan tea base enters the steaming stage, steaming makes the Zijuan tea semi-finished product soft and sticky, with uniform hardness and dryness, and the same wetness and dryness. The steaming time is controlled according to the age of the Zijuan tea. The steamed Zijuan tea base can be made into machine-made Zijuan tea and Fuzhuan tea after pressing.

[0010] Furthermore, the flowering and drying stages of step S2 are critical. Flowering is the key to producing sporangia (golden flowers) of Eurotium cristatum in the Zijuan tea leaves through the application of appropriate temperature and humidity. The flowering period is 12-15 days, and the drying period is 5-7 days. The temperature required for the growth of Eurotium cristatum in Zijuan tea is 15-34°C and the relative humidity is 65%-85%, with the optimal temperature being 26-28°C and the humidity being 8%. Flowering is regulated in a smart drying room with automatic temperature and humidity control and online monitoring. Unlike traditional methods, the Zijuan tea leaves are packaged in kraft paper boxes rather than kraft paper.

[0011] Furthermore, in step S2, the purple tea bricks that are not wrapped in kraft paper after flowering are broken up and pressed into three-layer lotus-shaped round cakes, which weigh 5 grams after drying. The purple tea wrapped in kraft paper directly becomes the finished product. The purple tea bricks that are rich in Aspergillus niger (golden flower) after flowering are broken up and mixed with an appropriate amount of ancient tree tea that is more than 100 years old, and pressed into three-layer lotus-shaped round cakes and round cakes weighing 5 grams. The 5-gram finished product is packaged in a bag of 500 grams, and small bags of three 5-gram round cakes are provided as free gifts.

[0012] The above technical solution has the following beneficial effects:

[0013] The ingredients of the Zijuan tea in the present invention include anthocyanins, Aspergillus niger, tea polyphenols, catechins, and amino acid powder. Since the Zijuan tea itself contains a high content of anthocyanins and various active ingredients beneficial to the human body, and the introduction of Aspergillus niger makes this tea have various health care functions such as lowering blood pressure, lowering blood sugar, lowering uric acid, lowering fat and protecting the liver, and losing weight. Through a special fermentation and cultivation process, the Zijuan tea and Fuzhuan tea form a unique taste and aroma, with a rich tea fragrance and a slightly sweet taste, and are deeply loved by consumers. The Zijuan tea is processed into Fuzhuan tea containing Aspergillus niger, and can also be blended with other teas, which not only improves the quality and taste of the tea, but also significantly improves the added value and market competitiveness of the tea. The Zijuan tea and Fuzhuan tea process of the present invention has broad market prospects and huge commercial value, and is worthy of further promotion and application. DETAILED DESCRIPTION

[0014] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0015] The process of processing Zijuan tea into Fuzhuan tea containing Eurotium cristatum involves the following steps: raw material collection and preparation, and a long-term cooperation agreement with the Yunnan Tea Research Institute to ensure the stability and quality of the raw material supply. The raw material is sun-dried raw leaves of Yunnan's unique Zijuan tea, which must be uniform in color, vibrant purple, and free of impurities. The Yunnan Tea Research Institute provides testing reports on the soil and tea grown to ensure that the raw materials meet food safety standards.

[0016] Preparations and rituals before making tea, preparing the equipment and tools needed for tea making, including tea steaming machines, pile-fermenting equipment, pressing machines, etc.

[0017] Zijuan tea is pile-fermented. Steam the tea in a tea steamer at a controlled temperature of 98-102°C for approximately five minutes. The steamed tea is then piled for fermentation, forming a conical pile at a height of 2-3 meters for approximately three to four hours. The pile is regularly turned to dissipate heat and maintain a temperature between 75-88°C to prevent overheating and tea deterioration.

[0018] Steam pressing is used to form the Zijuan tea after pile fermentation. First, an appropriate amount of Zijuan tea juice is added to the Zijuan tea leaves to improve adhesion and moisture. The juice is brewed at a ratio of 1 jin (100 grams) of Zijuan tea to 20 jin (100 grams) of water. After brewing, the juice is evenly sprayed over the tea leaves. The moisture content of the tea leaves is controlled between 25% and 28%, adjusted according to seasonal weather conditions, with a slightly lower moisture content in spring and summer and a slightly higher moisture content in autumn and winter. The processed Zijuan tea leaves are then placed in a press and steam pressed to form a compact Fuzhuan tea shape.

[0019] The pressed Fuzhuan tea is placed in a smart drying room for blooming and drying. The temperature and humidity in the drying room must be strictly controlled, maintaining the temperature between 15°C and 34°C, with an optimal temperature of 26°C to 28°C; and the humidity between 65% and 85%, with an optimal humidity of 8%.

[0020] The flowering period lasts 12-15 days, during which time the tea leaves should be regularly checked to ensure the proper growth of the golden flowers (Eurocystis cristatum). After the flowering period is complete, the leaves are dried for 5-7 days. The dried leaves should reach the desired moisture content and taste.

[0021] Finished product packaging involves packaging the dried Fuzhuan tea. One packaging method involves packaging the tea directly into a kraft paper box. Another method involves breaking the tea leaves into small, three-layered, eight-petal lotus-shaped cakes, each weighing 5 grams, before packaging. We offer packaging options of varying sizes and weights, tailored to customer needs, such as a 500-gram bag or a small gift bag of three 5-gram round cakes.

[0022] The present invention uses the deep-processed products of Zijuan tea series to protect various products containing this tea, including medicines, foods, beverages, etc.

[0023] Example 2: Based on Example 1, raw material selection and pretreatment were carried out in collaboration with the Yunnan Tea Research Institute. High-quality, uniformly colored sun-dried raw Zijuan tea leaves were selected as raw material. Pretreatment of the raw material, including impurity removal and screening, was performed to ensure the purity and consistency of the tea leaves.

[0024] Pile fermentation optimization utilizes advanced fermentation techniques, such as microbial regulation, to optimize the fermentation process and improve tea quality. During the fermentation process, the fermentation level and temperature of the tea are regularly monitored, and the conditions are adjusted promptly to ensure even fermentation without overproduction.

[0025] Innovations in pressing and flower development: Zijuan tea leaves undergo special treatment before pressing, such as adding appropriate amounts of microbial agents or plant extracts to improve the tea's adhesion and moisture content, while also promoting the growth of the golden flowers. Innovative flower development techniques, such as using bioreactors for flower development, shorten flower development time and improve the quality of the golden flowers.

[0026] During the tea's blooming process, online monitoring technology is used to monitor and adjust the temperature and humidity in the drying room in real time, ensuring stable and precise blooming conditions. Advanced drying techniques, such as vacuum drying or freeze drying, are employed for drying and packaging to preserve the tea's original flavor and nutrients. Environmentally friendly, moisture-proof, and anti-oxidation packaging materials are used to extend the tea's shelf life and quality stability. Personalized packaging options, such as custom packaging and gift packaging, are available to meet the needs and preferences of diverse customers.

[0027] The ingredients of the golden Zijuan tea of the present invention include anthocyanins, Eurotium cristatum, tea polyphenols, catechins, and amino acid powder. Since the Zijuan tea itself contains a high content of anthocyanins and various active ingredients beneficial to the human body, and the introduction of Eurotium cristatum makes the tea have various health care functions such as lowering blood pressure, lowering blood sugar, lowering uric acid, lowering fat and protecting the liver, and losing weight. Through a special fermentation and cultivation process, the Zijuan tea and Fu brick tea form a unique taste and aroma, with a strong tea fragrance and a slightly sweet taste, and are deeply loved by consumers. The Zijuan tea is processed into Fu brick tea containing Eurotium cristatum and can also be blended with other teas, which not only improves the quality and taste of the tea, but also significantly improves the added value and market competitiveness of the tea.
