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.
