The invention relates to the fine chemistry industry synthesis field, and especially relates to an environmentally-friendly synthesis method of vitamin E. The method comprises the following steps: adding 150-200 parts by weight of toluene into a reaction device, sequentially adding 40 parts by weight of 2,3,5-trimethylquinhydrone and 40-80 parts by weight of isophytol under mechanical stirring, slowly adding 1.5-2.5 parts by weight of magnesium chloride and 0.8-1.2 parts by weight of a magnesium oxide supported silica catalyst after the above obtained reaction system is fully dissolved and clear, closing the reaction system, allowing the reaction system to undergo a reaction under a vacuum degree of -0.07 - -0.05MPa at a temperature of 55-65DEG C for 1.5-2.5h, and allowing toluene reflux to be maintained and generated water to be distilled out with the toluene reflux in the reaction to be in favor of the implementation of the reaction; and recovering the catalyst and the above solvent, and carrying out reduced pressure distillation of the solvent-distilled reaction system to obtain a required pale-yellow oily vitamin E product. The method has the advantages of repeated use of the supported catalyst, high yield, low energy consumption and environmental protection.

The invention provides a decoloration and purification method for vitamin E. The method includes the following steps: (a) providing a composite decoloration agent to perform decoloration to a vitamin E product; (b) eluting the decolored vitamin E in the step (a) through column chromatography by means of an eluting agent, and collecting an eluent component; and (c) concentrating the eluent component in the step (b) to prepare the decolored and purified vitamin E. In the step (a), the composite decoloration agent includes activated clay, activated carbon, diatomite and magnesium silicate according to 100:50-100:30-70:10-50 by mass. The decoloration and purification method can shallow the color and reduce the viscosity of vitamin E, thereby improving flowability and also increasing the purity of the vitamin E. The vitamin E is low in loss and has a high recovery rate during the decoloration and purification.

The invention relates to reparation method of a fortified vitamin E-containing fresh cheese. The method comprises the following steps: 1, dissolving vitamin E and beta-whey protein in water, stirring with magnetic force so as to obtain a reaction solution, and dialyzing in a dialyzing bag so as to obtain a self-assembly beta-lacto globulin-fortified vitamin E product; 2, inoculating lactococcus in an M17 culture medium, carrying out continuous activation for three generations to obtain a bacterium solution, and inoculating the bacterium solution in a whey basal culture medium for culturing so as to obtain a fermentation agent; 3, mixing the self-assembly beta-lactoglobulin-fortified vitamin E product and fresh cow milk, adding calcium chloride, inoculating the fermentation agent, carrying out acid production, and curding so as to obtain the fortified vitamin E-containing fresh cheese. In the method, only beta-lactoglobulin serves as a carrier, no other coupling reagents, emulgators and organic solvents are added; on one hand, the food safety of the fortified vitamin E-containing fresh cheese is good, on the other hand, the edibleness and the utilization rate of the vitamin E are increased; the shelf life of the fresh cheese is prolonged.
