Description

Technical Field

[0001] This invention relates to the field of functional beverage technology, and in particular to an oxygen-carrying nanobubble water and its preparation method. Background Technology

[0002] With the accelerating global trend of health-conscious consumption, people are placing higher demands on the functionality of drinking water. Beyond basic hydration and thirst quenching, the introduction of specific functional factors into water to assist the body in regulating its physiological state has become an important direction for the development of functional beverages. Among these, oxygen, as an essential gas molecule in human metabolism, plays a significant role in maintaining cell vitality, accelerating lactic acid metabolism, and enhancing immune regulation. Therefore, oxygen-rich water products are gradually emerging in niche markets such as those targeting athletes, those with sub-optimal health, and the elderly seeking health and wellness.

[0003] However, the existing oxygen-enriched water market faces a series of technical challenges and bottlenecks:

[0004] 1. Limited gas dissolving capacity: The solubility of oxygen in ordinary water bodies is usually no more than 8-10 mg / L at normal temperature and pressure. The effect of mechanical aeration and pressurized oxygen injection on increasing the dissolved amount is limited, and there is a lack of micro-control of gas form.

[0005] 2. Significant gas escape and poor stability: Oxygen molecules are extremely prone to escape in water, especially during storage or transportation. Bottle vibration or temperature changes will accelerate the escape of dissolved oxygen, resulting in a significant decrease in oxygen content when consumed, making it difficult to guarantee product efficacy.

[0006] 3. Large bubble size and poor active release: The bubble size generated by traditional bubble technology is generally in the tens of micrometers or even millimeters. It has high buoyancy, low stability, and rapid gas release, making it difficult to achieve slow release or osmotic oxygen supply in the human body.

[0007] 4. Insufficient packaging sealing and lack of product standards: Currently, most oxygen-enriched water is packaged in ordinary PET bottles or aluminum foil bags, which have limited ability to prevent oxygen molecule escape. Furthermore, the lack of systematic preparation standards and testing indicators hinders the large-scale promotion of the product.

[0008] In recent years, nanobubble technology, as an emerging microfluidic and gas-liquid interface control method, has shown great potential in fields such as medicine, environmental protection, agriculture, and water treatment. Nanobubbles possess the following significant characteristics: their diameter is typically between 10 and 200 nanometers, exhibiting high dispersibility; they carry a negative charge, are stable in suspension, and are not prone to aggregation, collapse, or floating; they have a large surface area, possessing good biopermeability and interfacial activity; and they can maintain their state in liquids for extended periods, demonstrating slow-release delivery capabilities.

[0009] Injecting oxygen into water using specialized equipment and then nano-processing it to form highly stable oxygen-carrying nanobubbles can not only significantly increase the dissolved oxygen concentration in the water, but also achieve slow release of active oxygen and osmotic oxygen supply, potentially overcoming the technical limitations of traditional oxygen-enriched water.

[0010] Although existing academic literature and experimental studies have confirmed that nano-oxygen bubbles have excellent oxygen supply and physiological regulation functions, to date, there is a lack of a mass-producible and controllable technology for preparing oxygen-loaded nano-bubble water products, both domestically and internationally. Most commercially available products use simple gas injection or pressurized bottle storage methods, which cannot form nanoscale bubble structures. Furthermore, there is a lack of a complete solution that combines bubble size control, enhanced gas stability, guaranteed drinking safety, and standardized preparation processes. Therefore, there is an urgent need for a highly efficient, stable, and health-beneficial oxygen-loaded nano-bubble water and its preparation method. Summary of the Invention

[0011] The purpose of this invention is to provide an oxygen-carrying nanobubble water and its preparation method. Through innovative technical means, it solves the technical problems of existing oxygen water products in terms of gas solubility, bubble stability, and continuous release, thereby providing consumers with efficient, stable, and health-beneficial oxygen water.

[0012] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0013] The present invention provides an oxygen-carrying nanobubble water, comprising: water and nano-sized oxygen bubbles dispersed in the water, wherein the particle size of the nano-sized oxygen bubbles is distributed in the range of 10 to 200 nm.

[0014] The dissolved oxygen content in the water is 25–45 mg / L;

[0015] The nanobubbles remain stably suspended in water for at least one week, with a gas evolution rate of less than 10%.

[0016] Preferably, the nanobubbles have a particle size of 10–100 nm.

[0017] Preferably, the oxygen-carrying nanobubble water also includes at least one of vitamins, minerals, collagen, enzymes, and antioxidants, with an addition amount of 0.001% to 0.01%.

[0018] The present invention also provides a method for preparing the aforementioned oxygen-carrying nanobubble water, comprising the following steps:

[0019] (1) Water source pretreatment: The water source is filtered through three stages and sterilized by ultraviolet light to produce drinking-grade pure water, removing impurities that may interfere with bubble formation and stability;

[0020] (2) Oxygen introduction and preliminary mixing: High-purity oxygen is introduced into the water flow through a Venturi tube gas-liquid mixing device to form a primary gas-liquid mixture;

[0021] (3) High-pressure shear homogenization: The primary gas-liquid mixture is subjected to high-pressure shear homogenization treatment, with a pressure range of 20 to 80 MPa;

[0022] (4) Ultrasonic nano-sizing treatment: The homogenized mixture is subjected to ultrasonic nano-sizing treatment to reduce the oxygen bubble particle size to 10-200 nm.

[0023] (5) Bubble stability control: control the surface charge, viscosity and temperature conditions of the liquid to improve bubble stability and suspension life in water, and avoid aggregation, collapse and oxygen escape.

[0024] (6) Detection and quality control: Detect dissolved oxygen content, bubble size distribution, pH value and redox potential value in water;

[0025] (7) Aseptic filling and sealing: Fill qualified products into oxygen-barrier packaging containers and seal them in an aseptic environment.

[0026] Preferably, in step (4), the ultrasonic frequency is 20–80 kHz and the power density is 5–20 W / cm². 2 .

[0027] Preferably, the ultrasonic treatment in step (4) causes the bubble particle size to be mainly distributed in the range of 10 to 100 nm.

[0028] Preferably, in step (5), bubble stability is enhanced by adding a charge regulator and / or a buffer.

[0029] Preferably, the oxygen barrier packaging container in step (7) is a multi-layer composite bottle, which has the properties of light protection, oxygen barrier, and pressure resistance.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Achieve precise generation and controllable distribution of nanoscale oxygen bubbles.

[0032] This invention solves the problems of excessively large bubble size, low solubility, and poor stability in traditional oxygen-enriched water by introducing a highly efficient Venturi tube gas mixing system, a high-pressure shear homogenization system, and an ultrasonic resonance nano-sizing system. It stably generates oxygen nanobubbles with a particle size of 10-200 nm under normal temperature and pressure or light pressure conditions, ensuring that the bubbles are suspended stably, difficult to float and break, and have good interfacial activity and penetration ability.

[0033] 2. Significantly improves dissolved oxygen concentration and storage stability

[0034] The target oxygen content is ≥25mg / L, which is superior to traditional oxygenated drinking water (generally <10mg / L). At the same time, the bubble stabilization tank and charge control technology maintain the bubble charge barrier effect, effectively preventing aggregation, rupture and oxygen escape, so that the product maintains a stable oxygen concentration throughout the transportation, storage and opening process.

[0035] 3. Construct a closed-loop preparation process to achieve controllable process parameters.

[0036] The system constructs a complete process from raw water pretreatment → oxygen injection → nano-processing → stabilization → quality inspection → aseptic filling → packaging and storage. With closed-loop monitoring of parameters such as temperature, pressure, flow rate, mixing ratio, and nano-level energy, it ensures batch consistency, meets drinking-grade process requirements, and is replicable for industrial production.

[0037] 4. Enhance the bioavailability of oxygen in the human body

[0038] By forming a stable group of oxygen nanobubbles, it can be slowly released after entering the human digestive tract and diffuse into the blood through the mucous membrane tissue, effectively improving tissue oxygen supply, enhancing microcirculation efficiency, and increasing metabolic activity. Compared with traditional large bubbles or simply injecting oxygenated water, it has a higher physiological function release efficiency.

[0039] 5. Meets diverse health needs and differentiated application scenarios

[0040] The target product can serve the following areas in terms of functionality:

[0041] Sports and fitness scenarios: Rapid oxygen replenishment before and after exercise to delay fatigue accumulation;

[0042] Medical and Rehabilitation Assistance: Used for sub-health conditioning and auxiliary improvement of insufficient oxygen supply to the heart and brain;

[0043] Beauty and skincare product base liquid: can be used as an oxygen-enriched cosmetic base liquid to increase the oxygen content of cells;

[0044] Daily health care and drinking water in high-altitude environments: Relieve chronic hypoxia and improve energy levels;

[0045] Nutritional product solvent: Water as an oxygen-activated carrier for nutrient absorption in specific populations.

[0046] 6. Establish a standardized, modular, and mass-producible system of oxygen-enriched functional aquatic products.

[0047] Unlike existing, rudimentary oxygenated water products on the market, this invention creates a complete preparation system and quality control system, which can be widely used in bottled water factories, customized nutritional beverages, health and wellness centers, hospital spas, and other places, and has flexibility and high scalability.

[0048] 7. Build core technology barriers to gain patent protection space.

[0049] Through original design of equipment structure, gas injection module, nanobubble control method, oxygen stabilization mechanism, packaging sealing structure and other key links, a systematic combination of technological innovations is formed, which provides basic support for the company to build a product system and expand extended products (such as hydrogen-oxygen, ozone-carrying, composite gas water, etc.), and establishes a clear intellectual property protection barrier.

[0050] 8. Promote the transformation of the functional drinking water industry from conceptualization to standardization.

[0051] Currently, the oxygen-enriched water industry suffers from low technological barriers, vague product efficacy, lack of regulation, and insufficient consumer trust. This invention, through systematic research and patent support, proposes a complete set of verifiable, replicable, traceable, and regulated technologies, which is expected to establish unified standards for the functional beverage industry and promote its healthy development.

[0098] This invention solves the technical challenges of existing oxygenated water products in terms of gas solubility, bubble stability, and continuous release through innovative technological means, thereby providing consumers with efficient, stable, and health-beneficial oxygenated water. It offers a functional oxygen-carrying nanobubble water and its preparation method, demonstrating significant development prospects and health benefits. Specifically, the beneficial effects of this invention include the following aspects:

[0099] 1. Increase the solubility of oxygen in water

[0100] Existing oxygenated water products generally have low oxygen solubility, and the dissolution efficiency is limited by the stability of the bubbles. Traditional dissolution methods often employ high-pressure dissolution or electrolysis, resulting in large bubbles that are ineffective at dissolving oxygen and are prone to escape, making it impossible to maintain consistent oxygen solubility. The purpose of this invention is to increase oxygen solubility to 5 to 10 times that of conventional oxygenated water through nanobubble technology. By using a nanobubble generator, oxygen is dissolved into bubbles smaller than 100 nanometers, thereby significantly increasing the contact area between the bubbles and water and improving the oxygen dissolution efficiency.

[0101] 2. Enhances bubble stability, ensuring sustained oxygen release.

[0102] Existing oxygen-water technologies suffer from poor bubble stability. Traditional methods produce large, easily broken bubbles, resulting in a short duration of oxygen dissolution in water. To ensure long-term stable oxygen dissolution in water, this invention enhances bubble stability through spin coupling and bubble stabilization technologies. Specifically, spin coupling effectively adjusts the spin state of oxygen molecules, enhancing their interaction with water and improving oxygen stability. During bubble generation, the size and distribution of the bubbles are precisely controlled to ensure the long-term stable presence of oxygen in water.

[0103] 3. Provides dual health benefits – synergistic effect of oxygen and hydrogen

[0104] Oxygen and hydrogen each possess unique health benefits. Hydrogen, with its powerful antioxidant properties, is widely used in anti-aging and antioxidant fields; oxygen, on the other hand, helps improve cell metabolism, enhance physical strength, and promote exercise recovery. Traditional technologies generally focus only on the dissolution effect of a single gas, while this invention dissolves both oxygen and hydrogen in water simultaneously, providing dual health support through synergistic effects. The purpose of this invention is to simultaneously dissolve hydrogen and oxygen in water, maximizing the health benefits of both through the synergistic effect of spin coupling and plasma excitation technology, providing functions such as exercise recovery, immunity enhancement, and antioxidant effects.

[0105] 4. Simplify production processes and reduce production costs.

[0106] Traditional oxygenated water production processes are complex, typically requiring high-pressure dissolution or electrolysis equipment, resulting in expensive equipment and complicated operation. This invention eliminates the need for high-pressure equipment by employing a gas dissolution method at room temperature and pressure, simplifying the production process. The gas dissolution process utilizes an optimized nanobubble generator and stability enhancement technology to achieve high gas dissolution efficiency and stability, reducing production costs. This method enables large-scale production, lowering the barrier to entry for oxygenated water production.

[0107] 5. Ensure a stable release of oxygen over a long period of time.

[0108] Existing oxygenated aquatic products suffer from easily broken bubbles and rapid release of dissolved oxygen, failing to provide sustained health benefits. This invention, through optimized bubble stability and continuous release technologies, enables a long-term, stable release of oxygen within the product. By enhancing bubble stability through spin coupling technology, oxygen and hydrogen can persist in the water and be released gradually, allowing consumers to receive a continuous oxygen supplement over a longer period.

[0109] 6. Meet consumers' diverse needs for healthy beverages

[0110] With increasing consumer health awareness, the market demand for functional beverages is growing, especially in areas such as sports recovery, immunity enhancement, and anti-aging. This invention improves the solubility and stability of oxygen and hydrogen in water, providing a more efficient and longer-lasting gas dissolution effect than existing technologies, thus meeting the growing market demand for healthy beverages. By offering dual health benefits, the oxygenated water of this invention will attract a wider consumer base, particularly athletes, fitness enthusiasts, and those focused on health management.

[0111] 7. Promote innovation and industrial development in oxygenated water technology.

[0112] This invention not only solves the problems of low solubility, poor stability, and continuous gas release in existing oxygenated water technology, but also promotes the innovative development of oxygenated water preparation technology. Through the technical solution of this invention, the oxygenated water industry can transition from traditional high-pressure dissolution methods to more efficient, environmentally friendly, and economical preparation methods. In the future, the technology of this invention can not only be applied in the field of oxygenated water, but also extended to the research and development of other functional water products, providing technical support for the rapid development of the health beverage industry.

[0113] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
