Problems solved by technology

Tea polyphenols have various physiological functions and effects such as scavenging free radicals, anti-aging, anti-tumor, lowering blood fat, antibacterial, and beauty. However, tea polyphenols are water-soluble, poorly fat-soluble and extremely unstable, and their bioavailability Low, easy to be oxidized, which limits its physiological functions and its application in food and pharmaceutical industries

Abstract

The invention relates to compound tea polyphenol nano emulsion as well as a preparation method and application thereof. The compound tea polyphenol nano emulsion is stable in properties, a particle size is smaller than 100nm, the compound tea polyphenol nano emulsion belongs to a W / O-type tea polyphenol nano emulsion and is prepared from the following raw materials by weight percent: 1 to 20 percent of tea polyphenol, 15 to 50 percent of composite surfactant, 1 to 15 percent of absolute ethyl alcohol, 10 to 25 percent of oil, and the balance of deionized water, and the sum of the weight percent of the raw materials is 100 percent. The W / O nano emulsion is simple in preparation method, small in nano emulsion drop particles, uniform in distribution, small in viscosity, good in mobility, capable of improving the stability of the tea polyphenol in food and medicine preparation, and capable of enlarging the application range.

Description

technical field [0001] The invention belongs to the technical field of research on tea polyphenol nano-emulsion materials, and in particular relates to a compound tea polyphenol nano-emulsion and its preparation method and application. Background technique [0002] Tea polyphenols, the general term for all polyhydric phenolic compounds in tea, are the main active ingredients of tea, accounting for 20% to 30% of the dry weight of tea. Tea polyphenols have various physiological functions and effects such as scavenging free radicals, anti-aging, anti-tumor, lowering blood fat, antibacterial, and beauty. However, tea polyphenols are water-soluble, poorly fat-soluble and extremely unstable, and their bioavailability Low, easy to be oxidized, which limits its physiological function can not be fully exerted and its application in food and medicine industries. [0003] Nanoemulsion, also known as microemulsion. It is composed of four parts: oil phase, water phase, surfactant, and ...
