Description

Technical Field

[0001] This invention relates to the field of loquat flower blended tea preparation technology, specifically to a loquat flower blended tea with antitussive and anti-inflammatory effects and its brewing method. Background Technology

[0002] Cough-relieving and phlegm-reducing teas are common dosage forms for daily conditioning and adjunctive treatment of respiratory diseases. Due to their convenience, natural ingredients, and low side effects, market demand has continued to grow in recent years. However, the following key issues still exist in existing technologies: 1. Limited effects of single ingredients or simple combinations: Traditional cough teas often rely on single ingredients (such as loquat leaves and honeysuckle) or simple compound formulas, lacking a synergistic mechanism of multiple components. For example, although loquat leaves can clear the lungs and relieve cough, they are less effective for sore throat and release of inflammatory factors caused by wind-heat invading the lungs; although honeysuckle can clear heat and detoxify, it is insufficient to relieve cough symptoms when used alone, and its cold nature can easily damage the spleen and stomach.

[0003] 2. Excessive use of cold ingredients limits the applicable population: Commercially available cough teas often use excessive amounts of cold ingredients (such as honeysuckle, chrysanthemum, and malva nut). Although they are for heat syndromes (such as yellow phlegm and sore throat), they do not balance the coldness. As a result, people with weak constitutions (such as weak spleen and stomach or yang deficiency) are prone to adverse reactions such as diarrhea and abdominal distension after taking them, which limits the applicable population. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a loquat flower blended tea with antitussive and anti-inflammatory effects and its brewing method are provided. This technical solution solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A loquat flower blend tea with antitussive and anti-inflammatory effects comprises the following components in parts by weight: 10-30 parts loquat flowers, 5-20 parts loquat leaves, 3-15 parts honeysuckle, 3-12 parts chrysanthemum, 2-10 parts licorice, 2-8 parts malva nut, and 1-5 parts monk fruit.

[0006] Preferably, the components include the following parts by weight: 20 parts loquat flowers, 10 parts loquat leaves, 10 parts honeysuckle, 6 parts chrysanthemum, 5 parts licorice, 5 parts malva nut, and 3 parts monk fruit.

[0007] Preferably, the loquat flowers are Dongtai loquat flowers, harvested during the peak blooming period, and have a moisture content of ≤8% after drying; the loquat leaves are tender leaves of the current year's loquat, which have been treated by blanching, rolling, and drying, and have an ursolic acid content of ≥0.5%; the honeysuckle is the dried flower bud of Lonicera japonica, a plant of the Caprifoliaceae family, and has a luteolin content of ≥0.1%.

[0008] A method for preparing a loquat flower blended tea with antitussive and anti-inflammatory properties includes: Based on the components of the blended tea, it is prepared into tea bags or loose tea; Take 3-5g of tea bag or loose tea and place it in the teaware; Pour in 200-300mL of purified water at 80-90℃, cover and let it steep; It can be filtered or drunk directly, and can be brewed repeatedly 2-3 times; The initial steeping temperature is 85℃ and the steeping time is 8 minutes. Subsequent steeping temperatures can be lowered to 80℃ and the steeping time extended to 10 minutes.

[0009] Preferably, the teaware is gently shaken 2-3 times during the steeping process.

[0010] Preferably, the soaking time with the lid on is 5-15 minutes.

[0011] Preferably, the step of preparing tea bags or loose tea according to the blended tea components specifically includes: Raw material pretreatment: Remove impurities from loquat flowers, loquat leaves, honeysuckle, chrysanthemum, licorice, malva nut, and monk fruit. Spray loquat flowers with water and let them soak for 2-4 hours. Shred loquat leaves and slice licorice. Drying treatment: Place the pretreated raw materials in a constant temperature drying oven at 60-70℃ and dry until the moisture content is ≤6% and sterilize; Grinding and blending: Grind the dried raw materials separately to 40-60 mesh, mix them evenly, and obtain the blended tea raw materials; Forming: The blended tea raw materials are packaged into tea bags or loose tea.

[0012] Preferably, the loquat leaves, after being shredded, are 2-3 mm wide; and the licorice slices are 2-4 mm thick.

[0013] Preferably, the process of moistening the loquat flowers is as follows: the loquat flowers are laid flat in a bamboo tray with a thickness of ≤5cm, sprayed with water until the surface is moist but without water accumulation, covered with a damp cloth and moistened for 3 hours, turning them over once during the period.

[0014] Preferably, the drying process employs a stepped heating method: an initial temperature of 50°C is maintained for 1 hour, the temperature is increased to 65°C and maintained for 2 hours, and finally, the temperature is maintained at 70°C for 1 hour; the sterilization process employs a combination of microwave and irradiation sterilization: first, microwave treatment is performed at a power of 300W for 2 minutes, followed by cobalt-60 irradiation at a dose of 7 kGy.

[0015] Compared with the prior art, the present invention provides a loquat flower blended tea with antitussive and anti-inflammatory effects and its brewing method, which has the following beneficial effects: This invention achieves a multi-target effect of "cough relief, anti-inflammation, and soothing the throat" through the synergistic combination of loquat flower, loquat leaf, honeysuckle, and chrysanthemum. Licorice root harmonizes the other herbs; its neutral nature and spleen-tonifying properties alleviate the cold properties of honeysuckle, chrysanthemum, and malva nut, reducing irritation to the spleen and stomach. Furthermore, a combined microwave and irradiation sterilization method is employed. Microwaves disrupt microbial cell membranes to enhance the irradiation effect, ensuring a high total bacterial count while minimizing degradation of active ingredients. Thus, through optimized ingredient combination, innovative sterilization process, and standardized brewing parameters, this invention significantly improves the efficacy, safety, and applicability of the cough-relieving and phlegm-reducing tea, providing a superior technical solution for respiratory conditioning products.
