Description

Preparation method of sugar-free bubble water
Technical Field
The application relates to the technical field of beverage processing, in particular to a preparation method of sugar-free bubble water.
Background
Water saturated with carbon dioxide dissolved in water is called carbonated water because it will contain CO2The existence of air bubbles is also called as 'bubble water'. Bubble water has been pursued by people more and more because of its health effects of helping to regulate acid-base balance of human body, enhancing gastrointestinal activity, suppressing appetite, eliminating constipation, blocking absorption of saccharides and fat, etc. Driven by the health-preserving requirement, the health trend of the beverage is gradually obvious, and more consumers pay attention to health and nutritionRelated concepts concern whether the beverage formula ingredient list is sugar-free, additive-free, etc.
Sugar substitutes (erythritol and sucralose) are mostly adopted as sweetening agents in the existing sugar-free bubble water, wherein the sucralose is used as a high-power sweetening agent, the sweetness is 600-650 times that of sucrose, the requirement of sweetness can be met only by adding a small amount of sugar, but the sucrose provides full mouthfeel and full and mellow flavor besides the sweetness. More importantly, sucrose, as an important carbohydrate, also provides a pleasant satisfaction to humans by stimulating the brain reward circuit. Sucralose has a heavy and bitter aftertaste, has peculiar tastes such as herbal taste and metallic taste, has a great difference from the taste of sucrose beverage, and is not good for consumers. And the erythritol is a corn extract, has low sweetness which is only one thousandth of that of the sucralose, is used as a sweetener to replace the sucralose, and has the defects of large addition amount, cost increase and the like when the same sweetness requirement is met. In addition, sugar alcohol substances are not easy to be absorbed by human bodies, and if people eat the sugar alcohol substances more, the burden of intestines and stomach is increased, and diarrhea is easy to appear. Studies have shown that excessive erythritol intake risks borborygmus, diarrhea, etc., with upper tolerance limits of 0.78 g and 0.71 g per kg body weight for adults and children, respectively. In order to ensure that children can eat it safely as well, the European food safety agency recommends an upper limit of erythritol content per serving of food or beverage of 0.6 g per kg of body weight.
The sweetness threshold value satisfactory to consumers is generally above 10% SEV (sugar equivalent value), and the higher the climate is, the higher the sweetness threshold value satisfactory to consumers in cognition is, for example, the sweetness of beverages in southeast Asia is generally above 16% SEV. The existing bubble water has the problems of low sweetness, light and tasteless, unobvious flavor and the like in order to achieve the purposes of reducing sugar and being free of sugar, and the drinking of consumers is affected.
Disclosure of Invention
In order to solve the problems of low sweetness, light and tasteless, unobvious flavor and the like of the existing sugar-free bubble water, the application provides a preparation method of the sugar-free bubble water, which adopts reasonable raw material collocation and preparation method, and adopts the compounding of the nerve sweet essence and the sucralose to make the sugar-free bubble water reach 12 percent of SEV sweetness, and simultaneously can effectively eliminate aftertaste influence caused by the sucralose and endow the sugar-free bubble water with perfect sucrose flavor.
