Description

Technical Field

[0001] This invention relates to the field of beverage preparation technology, and in particular to a formula for a functional beverage and its preparation method. Background Technology

[0002] With the accelerating pace of modern life and the upgrading of health consumption awareness, consumers' demand for daily beverages has shifted from basic thirst quenching and refreshing to nutritional support. Functional beverages aim to provide benefits to the human body in different scenarios such as efficient work, exercise recovery, or work-rest regulation by scientifically formulated functional ingredients targeting specific physiological needs (such as energy replenishment, stress relief, sleep support, and immune enhancement).

[0003] The prior art patent document CN109287909B discloses a "Monk Fruit Functional Beverage and its Preparation Method," which is made from the following ingredients in parts by weight: 5-10 parts monk fruit, 1-2 parts honeysuckle, 1-2 parts chrysanthemum, 1-2 parts Imperata cylindrica root, 1-2 parts mesona chinensis, and 1-2 parts licorice. The monk fruit functional beverage and its preparation method provided by this invention use only traditional Chinese herbs in the formula, without adding any preservatives, pigments, flavorings, or chemically synthesized raw materials, ensuring the product's green and healthy qualities. Using monk fruit as the main ingredient, supplemented with licorice, honeysuckle, chrysanthemum, mesona chinensis, and Imperata cylindrica root, it is simmered at high temperatures, ensuring both good taste and enhanced efficacy.

[0004] The patent document with authorization announcement number CN101223998A discloses "a formula and preparation method of a functional sports drink", which includes the following components: 0.06-0.10% tea polyphenols, 0.06-0.10% glucosamine hydrochloride, 0.05% sodium chloride, 0.008% potassium chloride, 0.05% magnesium sulfate, 4-8% white sugar, 0.5%-2.5% β-cyclodextrin, and 0.03%-0.09% citric acid; the above proportions are mass-volume concentrations. The sports drink designed using the technical solution of this invention not only has the advantages of replenishing water, energy, electrolytes, and nutrients, but also relieves stress, improves cognitive ability, enhances immunity, and improves athlete performance.

[0005] While existing technologies can achieve the green and healthy attributes of beverages without preservatives, colorings, flavorings, and chemically synthesized ingredients, and also endow them with various health benefits such as soothing the throat, relieving heat, and clearing the lungs, and are low in calories suitable for obese individuals and those with high blood pressure, high cholesterol, or high blood sugar, and can also provide basic functions such as hydration, energy replenishment, electrolyte replenishment, and nutrient supplementation, and further relieve stress, improve cognitive ability, enhance immunity, help improve athletic performance, and promote post-exercise recovery, current technologies do not incorporate differentiated formulas designed based on the body's 24-hour physiological activity patterns. A single formula cannot simultaneously address the differentiated physiological needs of the body for daytime energy replenishment, cognitive enhancement, and nighttime metabolic repair and immune regulation. Functional ingredients are often added in isolation, lacking synergistic design and failing to avoid antagonistic interactions between ingredients, resulting in significantly reduced actual efficacy. They also rely on high doses of synthetic functional ingredients, which can easily cause side effects and have low bioavailability. Furthermore, the lack of targeted delivery design makes the ingredients easily destroyed by stomach acid. In addition, the manufacturing process can easily cause a large loss of heat-sensitive bioactive ingredients. Some products also contain high levels of sucrose and artificial sweeteners, limiting the target population. Overall, a systematic nutritional intervention system has not been formed, making it difficult to achieve a balance between functional synergy, safety assurance, ingredient utilization, and product stability in functional beverages. Consequently, they cannot meet consumers' high-quality demands for precise nutrition and suitability for all scenarios in functional beverages. Summary of the Invention

[0006] Purpose of the invention: The purpose of this invention is to provide a formula for a functional beverage and a method for preparing it, so as to solve the problems mentioned in the background art.

[0011] According to another aspect of the present invention, a method for preparing a functional beverage is provided, comprising the following steps: S1. Mix the daytime guarana extract, theanine, and purslane extract in a certain proportion, add 2 times the weight of anhydrous ethanol and ultrasonically disperse to form a complex energy cluster dispersion. Mix the nighttime jujube seed oil and β-cyclodextrin in a weight ratio of 1:4, then shear at high speed to form an inclusion complex, and then mix with γ-aminobutyric acid and passionflower extract. At the same time, prepare gastric-soluble, enteric-soluble, and sustained-release capsules for later use. S2. Pour purified water into a low-temperature mixing tank and control the temperature at 5-8℃. Then add erythritol, steviol glycosides or mogrosides, potassium citrate or malic acid, and stir at 300 rpm until completely dissolved to obtain the base solutions for the daytime and nighttime versions. Then, add and mix the daytime and nighttime versions separately. For the daytime version, first add a natural antioxidant system and a targeted nutrient fortifier to its base solution, and stir at 500 rpm for 10 minutes. Then add a gastric-coated targeted delivery carrier and shear at 800 rpm for 5 minutes to ensure uniform dispersion of the gastric-coated targeted delivery carrier. For the nighttime version, first add an immune modulator and metabolic optimizer and a natural soothing system to its base solution, and stir at 400 rpm for 12 minutes. Then add an enteric-coated and sustained-release targeted delivery carrier in sequence and stir at 350 rpm for 8 minutes to obtain a mixture of the daytime and nighttime versions. S3. Pass the mixture of daytime and nighttime formulations into an ultra-high pressure homogenizer, control the pressure at 80-100MPa and the temperature at 10-15℃, homogenize twice to homogenize the system particle size to ≤1µm, and obtain a homogenized liquid. S4. Pass the homogenized daytime and nighttime liquids into a pulse electric field sterilization device, control the electric field strength to be 35-45kV / cm, the pulse width to be 20µs, and the treatment time to be 60s, so that the total number of microorganisms in the sterilized liquid is ≤10CFU / mL, and obtain sterilized liquid. S5. Quickly fill the sterilization solutions for daytime and nighttime use into aseptic PET bottles, and use a nitrogen-filled capping process to control the nitrogen purity to ≥99.99% and the residual oxygen in the bottle to ≤0.5%, to obtain the finished functional beverage.

[0012] Preferably, in S1, the ultrasonic dispersion power of the daytime composite energy cluster is 250W, and the ultrasonic dispersion time is 15min; the high-speed shearing speed of the jujube seed oil and β-cyclodextrin in the nighttime version is 10000r / min, and the high-speed shearing time is 20min; the gastric-coated capsules are prepared by spray drying, with a core material to wall material weight ratio of 1:3, an inlet air temperature of 120℃, an outlet air temperature of 60℃, and a particle size controlled at 1-3µm; the enteric-coated capsules are prepared by complex coagulation, and the sustained-release capsules are prepared by ionogel method, with the particle size of both types of capsules controlled at 2-5µm.

[0016] Beneficial effects: By combining active ingredients that are adapted to the human body's diurnal rhythm with an intestinal-targeted delivery structure, the stability and rhythmic synergistic effect of functional ingredients are improved, reducing the degradation and loss of active ingredients by the upper gastrointestinal environment. This achieves precise matching between ingredient release and the human body's physiological rhythm, effectively balancing the immediate efficacy and long-term maintenance of active ingredients. The low-temperature miscibility control and aseptic filling process in the preparation stage further optimize the uniformity of the liquid, reducing the inactivation or aggregation of functional ingredients. The overall solution improves nutrient absorption efficiency while adapting to the needs of the human body's activity patterns, solving the problems of traditional functional beverages such as single function, easy degradation of ingredients, poor rhythm adaptability, and low absorption and utilization rate. It provides a technical path that combines functionality and safety for nutritional intervention for people with disordered work and rest and rhythm imbalance. Attached Figure Description

[0054] To illustrate the use of the functional beverages described in this invention, functional beverages prepared in Examples 1-3 and Comparative Examples 1-3 were subjected to performance tests. The test methods are as follows: Retention rate of core functional ingredients (%): The content of guarana natural caffeine in the daytime sample and γ-aminobutyric acid (GABA) in the nighttime sample were detected by high performance liquid chromatography (HPLC) and the retention rate relative to the initial amount of raw materials was calculated.

[0055] Bioavailability of functional components (%): The samples were processed using an in vitro simulated human gastrointestinal digestion model (artificial gastric juice + artificial intestinal juice), and the content of absorbable functional components after digestion was determined by HPLC to calculate the bioavailability.

[0056] Sensory evaluation (out of 10): 30 professional food sensory evaluators were invited to conduct blind evaluations of the samples from four dimensions: color, aroma, taste, and aftertaste. Each dimension was scored out of 2.5 points, and the average of the total scores was taken.

[0057] Total microbial count (CFU / mL): Detected according to the method of GB4789.2.

[0058] Shelf life at room temperature (months): Using the accelerated test method, the sample is stored in a constant temperature and humidity chamber at 37℃ and 75% relative humidity. The time when the sample becomes cloudy, precipitated, or develops an odor is observed, and the shelf life at room temperature (25℃) is calculated.

[0059] Anti-fatigue effect (mouse weight-bearing swimming time: min): 60 SPF-grade mice were randomly divided into 6 groups and administered the corresponding samples by gavage. After 28 consecutive days of gavage, a weight-bearing swimming test was conducted, and the exhaustion swimming time of the mice was recorded.

[0060] Sleep improvement efficacy rate (%): 180 volunteers with poor sleep quality and difficulty falling asleep were randomly divided into 6 groups. Each group drank 200mL of the corresponding nighttime sample every night for 28 consecutive days. The effective criteria were shortened sleep onset time, reduced nighttime awakenings, and increased sleep duration. The efficacy rate was then calculated.

[0061] The test results are shown in the table below: As can be seen from the comparison of the examples and comparative examples, the present invention, based on the design concept of "rhythm adaptation + biosynergy + targeted delivery", combines natural active ingredients such as guarana extract and jujube seed oil, which greatly improves the precise nutritional intervention effect of functional beverages. Compared with traditional products, the present invention has better functional synergy and can simultaneously achieve gentle and long-lasting energy supply, promote deep sleep, and improve the bioavailability of ingredients. It has high overall efficacy and low adverse reaction rate. The present invention solves the problems of single function, insufficient bioavailability and poor scene adaptability of traditional functional beverages through the synergy of complex bioactive clusters, layered targeted delivery and low temperature integrated process. At the same time, it has the safety of natural ingredients, avoids the health risks of high doses of synthetic products, and has a wide range of raw material sources, simple preparation process, and long-term freshness without the need to add preservatives, providing a more comprehensive beverage choice for people with health needs at different times.
