Description

Technical Field

[0001] The invention belongs to the technical field of substitute teas, and particularly relates to a beauty-enhancing substitute tea based on Chinese herbal medicine and a preparation method thereof. Background Art

[0002] With increasing awareness of health and wellness, Chinese herbal tea substitutes, owing to their natural and environmentally friendly properties, have become a popular choice for consumers in their daily beverages. However, the current Chinese herbal tea substitutes on the market still have many shortcomings in terms of formula design, processing technology, and efficacy.

[0003] Most existing Chinese herbal tea substitute products use single flowers and herbs as raw materials, or are simply compounded. Although this type of formula design improves the taste to a certain extent, it lacks in-depth research on the balance of medicinal properties and synergistic enhancement.

[0004] The use of a large number of cold ingredients can easily lead to spleen and stomach deficiency with long-term consumption, violating the principles of holistic conditioning and balancing yin and yang in Traditional Chinese Medicine. Furthermore, the processing technique commonly used is a high-temperature baking method of 120-150 degrees Celsius. This crude method, which fails to optimize processing conditions for the specific characteristics of different ingredients, results in a significant loss of heat-sensitive ingredients such as chlorogenic acid and flavonoids, with a retention rate of less than 50%, severely weakening the product's health benefits.

[0005] In addition, the efficacy verification of existing products mostly remains at the traditional experience level and lacks the support of modern pharmacological data, which makes their efficacy mostly limited to basic health care functions, making it difficult to achieve precise regulation of chronic disease management and unable to meet consumers' increasingly diverse and personalized health needs. Summary of the Invention

[0006] The purpose of the present invention is to provide a beauty-enhancing substitute tea based on Chinese herbal medicine and a preparation method thereof, so as to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A beauty-enhancing substitute tea based on Chinese herbal medicine comprises the following raw materials in parts by weight: 8-10 parts of fresh salvia miltiorrhiza, 8-12 parts of polygonatum odoratum, 6-8 parts of rose flowers, 10-12 parts of red dates, 5-6 parts of longan pulp, 8-10 parts of wolfberry, 5-10 parts of lily, 5-10 parts of poria cocos, 5-8 parts of mulberry leaves, 2-3 parts of kudzu root, and 5-8 parts of flavor regulator.

[0009] Preferably, the flavor modulator includes β-cyclodextrin, oligofructose, resistant dextrin and citric acid.

[0010] A method for preparing a beauty-enhancing substitute tea based on Chinese herbal medicine comprises the following steps:

[0011] S1. Raw material screening and pretreatment

[0012] According to the functional requirements, 8 parts of fresh salvia miltiorrhiza, 10 parts of polygonatum, 7 parts of rose, 8 parts of red dates, 6 parts of longan pulp, 8 parts of wolfberry, 10 parts of lily, and 10 parts of poria were selected as raw materials, and the proportion of each component was determined;

[0013] Impurity removal: Use color sorters combined with manual sorting to remove moldy and insect-eaten raw materials to ensure that the purity of raw materials is ≥99%.

[0014] Ozone sterilization: Place the raw materials in an ozone concentration of 3ppm for 10 minutes to reduce the total colony count to ≤100CFU / g;

[0015] Low-temperature drying: Dry in a vacuum drying oven at 40 degrees with controlled humidity (from 60% to 5%) until the moisture content is ≤8% to avoid damage to heat-sensitive components;

[0016] S2. Efficient extraction of active ingredients

[0017] Composite enzymatic hydrolysis for cell wall breaking: Grind the dry raw materials into 80-100 mesh, add 0.6% W / W cellulase and 0.4% W / W pectinase, adjust the pH to 4.5-5.5 with citric acid, and perform enzymatic hydrolysis at 45-50 degrees for 1.5-2 hours to make the cell wall breaking rate ≥90%.

[0018] Ultrasonic-microwave synergistic extraction: The enzymatically hydrolyzed material was mixed with deionized water at a ratio of 1:15-20 (W / V), and extracted in a 40KHz ultrasonic reactor at 50-55 degrees for 20-30 minutes while simultaneously applying 300W microwave power.

[0019] Membrane separation and purification: pass through 0.45μm microfiltration membrane and 10kDa ultrafiltration membrane in sequence to intercept 1-10kDa active ingredients and remove large molecular impurities;

[0020] S3, Flavor Modification

[0021] Add 1-1.5% w / w β-cyclodextrin and 0.2% w / w γ-aminobutyric acid to the extract and stir at 60°C for 1 hour;

[0022] Prebiotic compound: 3% w / w fructooligosaccharide and 2% w / w resistant dextrin are added to regulate intestinal flora and improve solubility to ≤30 seconds;

[0023] S4. Finished product shaping and sterilization

[0024] Low-temperature spray drying: Control the inlet air temperature at 80-85°C and the outlet air temperature at 50-55°C to prepare instant tea powder, so that the moisture content is ≤4% and the solubility is ≥98%.

[0025] Nitrogen-filled packaging: Aluminum foil bags are filled with nitrogen and packaged, 2g per bag, ensuring that the residual oxygen is ≤0.5%.

[0026] Electron beam sterilization: irradiation with a dose of 8-10kGy ensures that microbial indicators meet the standards and the active ingredient retention rate is greater than 95%.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention avoids the problem of spleen and stomach deficiency and coldness caused by an excessively high proportion of cold ingredients in traditional products by scientifically combining Chinese herbal medicines and using them as substitute tea. At the same time, the invention uses composite enzymatic cell wall breaking technology and adds cellulase and pectinase to achieve a cell wall breaking rate of ≥90% under suitable pH and temperature conditions, greatly destroying the plant cell wall structure and promoting the release of active ingredients. The ultrasonic-microwave synergistic extraction technology utilizes the cavitation effect of ultrasound and the thermal effect of microwaves to accelerate the diffusion rate of active ingredients into the solvent and improve the extraction efficiency.

[0029] The formula of the present invention is used for female products and not only has the health care functions of nourishing the skin and beautifying the body, but also can better meet the increasingly diverse and personalized health needs of consumers through scientific formula and advanced technology.
