Abstract

The invention belongs to the technical field of food processing and particularly relates to oil-water-soluble rosemary extract and a preparation method and application thereof. The preparation methodcomprises mixing powdery rosemary extract and an extraction solvent, carrying out extraction and solid-liquid separation to obtain a clear liquid, concentrating the clear liquid to obtain rosemary extract, preheating the rosemary extract to 40-90 DEG C, adding an oil-soluble emulsifier and a water-soluble emulsifier into the extract, and carrying out stirring emulsification at 40-90 DEG C to obtain the oil-water-soluble rosemary extract. The preparation method has simple processes, utilizes a scientific and reliable principle and utilizes easily available raw materials. The oil-water-soluble rosemary extract is liquid and transparent, does not product precipitates, has good fluidity, can be fully dispersed in the oil phase or the water phase, is not layered after long-term standing, has good stability and can be widely used in the fields of oil, water and an oil-water mixture.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an oil-water soluble rosemary extract and a preparation method and application thereof. Background technique [0002] Rosemary is a perennial herb of the family Lamiaceae, which is rich in diterpene phenolic components and has obvious anti-oxidation, anti-tumor, antibacterial and other activities. [0003] As a new type of natural antioxidant, rosemary extract, whose main antioxidant components are carnosic acid and carnosol, has the advantages of safety, broad spectrum, high efficiency, high temperature resistance, etc., and is widely used in food, health care Products, cosmetics and other fields, with broad application prospects and huge market potential. [0004] At present, the types of main products on the market are powdery rosemary extract and oily liquid rosemary extract, but powdery rosemary extract has low solubility in edible oil, dissolves slowly,...
