Problems solved by technology

However, they introduce foreign enzymes in the production process, which is prone to by-products and unpredictable hazards
[0004] There are also many related reports on the separation and purification process of α-arbutin. Patent CN104911238A discloses the purification of α-arbutin fermentation liquid by nanofiltration method. - For arbutin, it is difficult to remove the sugar in it
Patent CN103773827A discloses the purification of α-arbutin fermentation liquid by macroporous resin adsorption method, but because it involves processes such as adsorption, washing impurities, elution and regeneration, the whole process is more complicated, time-consuming and not high in efficiency
In the α-arbutin method of chemical synthesis, there are also some methods for purification by adding organic solvents to crystallize the product, but it is difficult to ensure that the organic solvents are completely removed, and the production process poses a greater safety hazard

Abstract

The invention relates to a method for preparing environment-friendly alpha-arbutin by using bioenzyme reaction and water crystallization purification. The preparation method of the environment-friendly alpha-arbutin comprises the following steps: bioenzyme-based alpha-arbutin synthesis: adding a 5-50 g / L alpha-arbutin enzyme into an enzyme reaction base solution, and reacting at 30-50 DEG C to obtain an alpha-arbutin primary product solution, wherein the enzyme reaction base solution for bioenzyme-based alpha-arbutin synthesis is composed of 5.0-15.0 wt% of disaccharide, 0.5-5.0 wt% of 1,4-hydroquinone, 0.02-0.08 wt% of sodium hydroxide, 0.1-2.0 wt% of aid and the balance of purified water; and purifying the alpha-arbutin primary product by water crystallization separation 3-7 times, thereby obtaining the environment-friendly alpha-arbutin. The method for preparing alpha-arbutin has the advantages of simple technique, high safety and low cost, and is suitable for mass production. The obtained alpha-arbutin product is environment-friendly, has the advantages of high purity, high stability and low sensitization, and can be used for various whitening products.
