Abstract

The invention discloses a preparation method of oxyresveratrol microcapsules and products thereof. The method comprises the following steps: (1) selecting beta-cyclodextrin, chitosan, Arabic gum, and maltodextrin as split timbers, adding water for preparing a split timber aqueous solution, heating the split timber aqueous solution so as to completely dissolve the split timbers, and carrying out sterilization and homogenization on the obtained object so as to obtain an emulsion; (2) adding oxyresveratrol into a small amount of ethyl acetate and petroleum ether mixed solvent, heating for dissolving so as to obtain an oxyresveratrol solution; (3) cooling the emulsion obtained in the step (1) to 45-50 DEG C, stirring the emulsion to completely uniformly mix the emulsion, so that an emulsion with a solid content of 25-50% is obtained, and adding the oxyresveratrol solution to re-homogenize, so that an oxyresveratrol and split timber emulsion is obtained; and (4) carrying out spray drying on the oxyresveratrol and split timber emulsion obtained in the step (3), so that oxyresveratrol microcapsule powder is obtained. The method disclosed by the invention has the advantages of high embedding rate, high sample loading quantity, good water solubility, high stability and not easiness for discoloration, and the like.

Description

technical field [0001] The invention relates to the technical field of processing polyhydroxy trans-stilbene natural products, in particular to a preparation method of oxidized resveratrol microcapsules and a product thereof. Background technique [0002] Oxyresveratrol (Oxyresveratrol) is the 2'-hydroxylation derivative of polyhydroxy trans-stilbene natural product resveratrol (Resveratrol) that has attracted much attention in recent years. Oxidized resveratrol is colorless or light yellow rod-like crystals, needle-like crystals. It is unstable in alkaline environment or high-temperature water environment. Because it has multiple phenolic hydroxyl groups, the ferric chloride reagent is dirty green, and it has anti-oxidation effect and inhibits protein kinase and other biological activities. [0003] The structural formula of oxidized resveratrol is as follows: [0004] [0005] oxyresveratrol or trans-2,3',4,5'-Tetrahydroxystilbene [0006] Studies in recent years hav...
