Abstract

The invention relates to microcapsules and a preparation method thereof, particularly to tea polyphenol liposoluble microcapsules and a preparation method thereof, wherein a core material of the tea polyphenol liposoluble microcapsules comprises tea polyphenol and reduced glutathione, a mass ratio of the tea polyphenol to the reduced glutathione is 95-99:1-5, a wall material of the tea polyphenol liposoluble microcapsules is one or a plurality of materials selected from arabic gum, dextrin, corn syrup, ethyl cellulose, methylcellulose, and hydroxypropyl methylcellulose phthalate, and a mass weight ratio of the core material to the wall material is 1:1-4. The tea polyphenol liposoluble microcapsule preparation method comprises the following steps: respectively preparing a core material emulsion liquid and a wall material solution, adding the core material emulsion liquid to the wall material solution, carrying out high speed stirring, homogenizing, and carrying out spray drying to obtain the tea polyphenol liposoluble microcapsules. The tea polyphenol liposoluble microcapsules have characteristics of fine average particle size and slow tea polyphenol release, such that anti-oxidation and absorption utilization efficiency of the tea polyphenol are substantially improved.

Description

technical field [0001] The invention relates to a microcapsule and a preparation method thereof, in particular to a tea polyphenol fat-soluble microcapsule and a preparation method thereof. Background technique [0002] Chemically synthesized antioxidants such as butylhydroxyanisole and dibutylhydroxytoluene commonly used in the food industry generally have certain toxicity. The development of new natural and non-toxic antioxidants has become a research focus, and tea polyphenols is one of them. Tea polyphenols are a mixture of polyhydric phenolic compounds present in tea leaves. They have good antioxidant properties, and their antioxidant properties are 10 to 20 times higher than that of vitamin E. An ideal food natural antioxidant. According to the clinical evidence of modern medicine, the most notable feature of tea polyphenols is its efficient ability to scavenge free radicals, which is helpful for liver protection, anti-cancer, anti-mutation, anti-tumor, anti-virus and...
