Problems solved by technology

[0002] Among the currently known functional sugar alcohol products, sorbitol has good fluidity and compressibility compared with other functional sugar alcohols, so it is widely used in the tableted sugar industry; Sorbitol is used as the main raw material, but in addition to its good fluidity and compressibility, sorbitol also has the characteristics of moisture absorption and hardening, especially in high temperature and high humidity environments; therefore, in the production process The temperature and humidity control requirements of the workshop are relatively high. After a period of production, the system needs to be cleaned frequently due to the problem of hardening and blocking materials. At the same time, the hardening also brings certain difficulties to the storage and transportation of sorbitol products, so sorbitol cannot be stored for a long time

Abstract

The invention discloses a preparation method of novel sorbitol, and relates to the technical field of preparation and application of eutectic functional sugars, and the technical scheme is as follows: glucose and cane sugar are proportioned according to a ratio, are subjected to fermentation conversion, and are directly hydrogenated to prepare a mixed solution of sorbitol and isomaltitol; and adding a certain proportion of polyethylene glycol into the mixed solution, blending, concentrating, and carrying out high-temperature spray crystallization to prepare eutectic particles of sorbitol and isomaltitol, thereby obtaining the novel sorbitol product. The preparation method has the beneficial effects that the eutectic has the characteristics of synergistic interaction, non-hygroscopicity and high stability of the isomaltitol, so that the prepared novel sorbitol product keeps the original good compressibility and flowability of the sorbitol; the pressed candy has the advantages that the pressed candy is not hardened after being placed for a long time, and is easy to produce, control and preserve, meanwhile, piebald does not appear on the surface of the produced pressed candy, and the packaging requirement is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of preparation and application of co-crystal functional sugars, in particular to a preparation method of novel sorbitol. Background technique [0002] Among the currently known functional sugar alcohol products, sorbitol has good fluidity and compressibility compared with other functional sugar alcohols, so it is widely used in the tableted sugar industry; Sorbitol is used as the main raw material, but in addition to its good fluidity and compressibility, sorbitol also has the characteristics of moisture absorption and hardening, especially in high temperature and high humidity environments; therefore, in the production process The temperature and humidity control requirements in the workshop are relatively high.
