Problems solved by technology

The method of the present invention produces fructo-oligosaccharides, so that the obtained fructo-oligosaccharides have a lower sugar content and good palatability, and making tea can improve the fragrance of tea soup, but this patent is inconvenient to carry out the continuous conduction water bath work of the mixture, which needs to be carried out Improve
[0005] However, there are still some deficiencies in the use of the existing high-kestose-content fructooligosaccharide preparation device. In the process of use, the production process of mixing, transporting, and water-bath integration of raw materials cannot be realized, which is not conducive to Industrialized production work, at the same time, it is inconvenient to carry out the continuous conduction water bath work of the mixture, so a preparation device for fructooligosaccharides with high kestose content is needed to solve the above-mentioned problems

Description

technical field [0001] The invention relates to the technical field of fructose production, in particular to a method and a device for preparing fructooligosaccharides with high content of kestose. Background technique [0002] Fructose-oligosaccharides, also known as oligofructose or sucrose trisaccharide oligosaccharides, are natural active ingredients present in fruits, vegetables, honey and other substances. They are excellent water-soluble dietary fibers. The transformed, refined and concentrated fructo-oligosaccharide has become a widely popular functional food base material in the international food market in the past ten years due to its superior physiological functions. Known as a healthy new sugar source in the 21st century, the physiological function of fructooligosaccharides will affect the crystallization of sucrose, and the activity of invertase will increase with the decrease of beet freshness. This sugar content can be used for beet preservation. [0003] Ac...
