Description

Technical Field

[0001] This invention belongs to the field of beverage preparation technology, and specifically relates to an alkaline ionized water beverage and its preparation method. Background Technology

[0002] With the improvement of people's living standards and the pursuit of a healthy lifestyle, consumers' demand for beverages has gradually shifted from simply quenching thirst to having specific health functions, such as alkaline ionized water beverages. These beverages have the effects of regulating the body's acid-base balance and promoting metabolism, and have attracted increasing attention from consumers. However, there are still many problems that need to be improved in the preparation technology and product quality of alkaline ionized water beverages.

[0003] (I) Water treatment and ion regulation issues Limitations of traditional water treatment methods: Many existing alkaline ionized water beverage preparation processes employ relatively simple water pretreatment methods, which are insufficient to effectively remove harmful substances such as heavy metals and organic matter from the water. For example, while common methods such as sand filtration and activated carbon filtration can remove some large particulate impurities and residual chlorine, their effectiveness in removing dissolved heavy metal ions (such as lead and cadmium) and small-molecule organic matter is limited. These residual harmful substances not only affect the safety of the beverage but may also react with subsequently added ionic components, affecting the stability and quality of the product.

[0004] Improper control of ion composition and ratio: Precise control of the types and ratios of ions is crucial in the preparation of alkaline ionized water beverages to achieve the desired health benefits and taste. However, some current processes lack precision in ion control. On the one hand, the differences in water quality from different regions are not fully considered, leading to unstable ion content in the product. On the other hand, the addition of alkaline mineral ions (such as calcium, magnesium, and potassium) is often not scientifically proportioned according to human needs and taste preferences. For example, excessive addition of calcium ions may result in a bitter taste, while insufficient ion concentration will fail to achieve the claimed functions of regulating acid-base balance.

[0005] (ii) Sterilization and stability issues Disadvantages of traditional sterilization methods: Some alkaline ionized water beverage manufacturers still use traditional sterilization methods, such as ozone sterilization. Although ozone sterilization can achieve sterilization at relatively low temperatures, it is prone to leaving residues in the water, producing unpleasant odors. Furthermore, ozone may react with bromide ions in the water to form bromate, a potential carcinogen that poses a threat to consumer health.

[0006] Poor Product Stability: During storage, alkaline ionized water beverages are prone to stability issues such as precipitation and stratification due to the interactions between ions and the influence of external environmental factors (such as temperature and light). This not only affects the product's appearance but may also lead to uneven distribution of ionic components, reducing product consistency and reliability. For example, some alkaline ionized water beverages containing multiple mineral ions may develop precipitation of calcium carbonate, magnesium carbonate, etc., after long-term storage, affecting the product's taste and sales.

[0007] (III) Flavor and Texture Issues Taste incongruity: Because alkaline ionized water beverages have a certain unique taste, such as a slightly bitter or salty flavor, if the relationship between various components is not effectively balanced during the preparation process, it can easily lead to a taste incongruity. For example, excessive alkalinity can make the beverage taste too bitter, affecting the consumer's drinking experience.

[0008] In summary, current alkaline ionized water beverage preparation technologies have many shortcomings, failing to fully meet consumers' demands for healthy, safe, and stable beverage products. Therefore, developing an innovative alkaline ionized water beverage preparation technology to solve these problems has significant market and social value. Summary of the Invention

[0020] In some embodiments of the present invention, in step (5), the mixed mineral brine is sterilized twice and then instantly cooled to below 30°C in a sterile environment before being filled.

[0025] The beneficial effects of this invention are: Precise regulation of acid-base balance: Through optimized preparation processes, the types and proportions of alkaline mineral ions (such as calcium, magnesium, and potassium) in alkaline ionized water beverages are precisely controlled, enabling more effective regulation of the body's acid-base balance. Compared to traditional products, this invention's beverage can specifically adjust the ion concentration according to the different constitutions of various individuals, ensuring precise regulation of the body's acid-base environment after consumption and preventing various symptoms caused by acid-base imbalance, such as fatigue and decreased immunity due to acidic constitution.

[0026] Enhanced antioxidant capacity: During the preparation process, a special ionization technology is used, which not only generates ionized water with alkaline properties, but also promotes the production of a certain amount of active hydrogen in the water. As a strong reducing agent, active hydrogen can effectively remove free radicals in the body and enhance the body's antioxidant capacity. This helps to slow down cell aging and provides consumers with more comprehensive health protection.

[0027] Promotes metabolism: The rich and well-balanced ionic components in alkaline ionized water beverages can participate in and promote the body's metabolic processes.

By precisely controlling the concentration of alkaline ions, it avoids excessive bitterness or saltiness, achieving a harmonious taste and bringing consumers a pleasant drinking experience.

[0031] Efficient preparation process: The preparation process employed in this invention has been optimized to simplify some cumbersome procedures while improving the efficiency of each production stage. For example, in the ion addition and mixing process, automated, precise metering and rapid mixing equipment reduces manual operation time and errors, thereby improving production efficiency.

[0032] Cost control: While ensuring product quality and performance, production costs have been effectively reduced by rationally selecting raw materials and optimizing production processes, giving the products a more significant price advantage in the market and enhancing their market competitiveness.
