Problems solved by technology
[0003] The existing technology adopts concentrated crystallization and decolorization crystallization process to remove impurities, that is, the filtrate is concentrated, crystallized, and centrifuged to obtain crude inositol, and then the crude inositol is dissolved, decolorized, crystallized, and centrifuged to obtain wet inositol, and then dried The finished product of inositol is obtained by dry treatment, and the process cycle is longer; and inositol cannot remove calcium, chloride and other ion impurities well in the process of impurity removal and purification, and the conductivity of inositol is relatively high; another technology is to use ion exchange process, but the separation and removal of impurities is carried out at normal temperature, and the inositol feed liquid is prone to crystallization in the separation column, so low-concentration feed liquid must be used for separation, the process time is long, the production efficiency is low, and in the long-term During the time separation process, it is easy to breed a large number of bacteria, resulting in the degradation of myo-inositol by microorganisms and reducing the yield of myo-inositol

Embodiment
[0037]The preparation method of the mixed solution in the following examples is:
[0038]According to the solid / liquid ratio of 1:4, add phytin to clear water, stir in a pressurized and stirred hydrolysis kettle and heat to 180℃, pressure 0.8MPa, hydrolyze at this temperature and pressure for 6 hours to obtain inositol hydrolysis liquid. Hydrolyze the inositol hydraulically into the neutralization kettle, that is, use 15% calcium hydroxide solution to neutralize to a pH of 8-10. The neutralization liquid is filtered to obtain the inositol filtrate. Mix the inositol filtrate and the refined mother liquor at a ratio of 1.6:1, and the test indicators of the mixture are as follows.

Abstract
The invention relates to a refining process for high-temperature rapid separation of an inositol filtrate, and belongs to the field of food additive refining processes. The process is an inositol refining process which is high in preparation purity, extremely low in impurity and extremely low in conductivity. The inositol produced by the refining process of the invention has a purity of 99.9 percent or more, a conductivity of 2 mu m / cm or less and a clarity of grade A, and impurities such as calcium and chlorine are almost zero. The inositol refining process of the invention has the characteristics of simple process, short production cycle and low requirements on equipment, and has the advantages of better impurity removal, desalination rate of 99.9 percent or more, prevention of microbialbreeding during production, reduction of microbial degradation loss, and improvement of production efficiency and inositol yield.
Description
Technical field[0001]The invention relates to the technical field of food additive refining technology, and relates to a refining process for preparing inositol with high purity, extremely low impurities and extremely low conductivity, in particular to a refining process for high-temperature and rapid dissociation of inositol filtrate.Background technique[0002]The chemical name of myo-inositol is cis-1,2,3,5-trans-4,6-cyclohexanol. Inositol is widely used in the food industry, pharmaceutical industry, feed industry and cosmetics industry, and its market prospects are very broad. According to statistics, the main consumer markets for inositol are the United States, Western Europe, and Southeast Asian countries. The total demand is about 6,000 tons per year. In recent years, the world's demand for inositol has been increasing year by year. Domestic inositol is mainly used in food and medicine, and its annual sales are gradually increasing.[0003]The prior art uses concentrated crystall...
