Description

Alkaline ionized water beverage and preparation method thereof Technical Field The invention belongs to the technical field of beverage preparation, and particularly relates to an alkaline ionized water beverage and a preparation method thereof. Background With the improvement of the living standard of people and the pursuit of healthy life style, the demands of consumers for beverages are gradually changed from pure quenching thirst to have specific health functions, such as alkaline ionized water beverages, which have the effects of regulating the acid-base balance of human bodies, promoting metabolism and the like, and the consumers are paid more attention to, however, the current alkaline ionized water beverages still have a plurality of problems to be improved in the aspects of preparation technology and product quality: Water quality treatment and ion regulation The traditional water quality treatment method has the limitation that the prior alkaline ionized water beverage preparation process adopts a simpler water quality pretreatment mode, and is difficult to effectively remove harmful substances such as heavy metals, organic matters and the like in water. For example, although the common methods such as sand filtration and activated carbon filtration can remove part of large-particle impurities and residual chlorine, the removal effect on soluble heavy metal ions (such as lead, cadmium and the like) and small-molecule organic matters is limited. These residual harmful substances not only affect the safety of the beverage, but also may react with the subsequently added ionic components, affecting the stability and quality of the product. The ion components and the proportion are not properly controlled, and in the preparation process of the alkaline ionized water beverage, the accurate control of the ion types and the ion proportion is important to realize the expected health effect and mouthfeel. However, some current processes lack precision in ion regulation. On one hand, the water quality difference of water sources in different areas cannot be fully considered, so that the ion content in the product is unstable, and on the other hand, when alkaline mineral ions (such as calcium, magnesium, potassium and the like) are added, scientific proportioning cannot be carried out according to the human body needs and the taste requirements. For example, excessive calcium ion addition may result in a bitter taste of the beverage, while too low an ion concentration may not achieve the stated acid-base balance adjustment function. (II) Sterilization and stability problems The traditional sterilization method has the disadvantage that part of alkaline ionized water beverage manufacturers still adopt the traditional sterilization method, such as ozone sterilization. Ozone sterilization can achieve a sterilization effect at a lower temperature, but is easy to remain in water to generate bad smell, and ozone can react with bromide ions in water to generate bromate, which is a potential carcinogen and forms a threat to the health of consumers. The product stability is poor, and the stability problems such as precipitation, layering and the like are easy to occur due to the interaction among ions and the influence of external environment factors (such as temperature, illumination and the like) in the storage process of the alkaline ionized water beverage. This not only affects the quality of the appearance of the product, but also may lead to uneven distribution of the ionic components therein, reducing the consistency and reliability of the product. For example, some alkaline ionized water beverages containing multiple mineral ions may exhibit precipitation of calcium carbonate, magnesium carbonate, etc. after long-term storage, affecting the mouthfeel and sales of the product. (III) flavor and mouthfeel problems The taste is not coordinated, because the alkaline ionized water beverage has a certain special taste, such as slightly bitter or salty taste, if the relationship among various components cannot be effectively balanced in the preparation process, the taste is easily inconsistent. For example, too much alkalinity can make the beverage too bitter in taste, affecting the consumer's drinking experience. In view of the above, the current alkaline ionized water beverage has a plurality of defects in the preparation technology, and cannot fully meet the demands of consumers on healthy, safe and stable beverage products. Therefore, an innovative alkaline ionized water beverage preparation technology is developed, the problems are solved, and the method has important market significance and social value. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides the alkaline ionized water beverage and the preparation method thereof, wherein the alkaline ionized water beverage has excellent product stability, cont
