Abstract

The invention provides a preparation method of a water-in-oil nanoemulsion. The method comprises the steps that PGPR (polyglycerol poly-ricinoleate) is added into liquid raw material oil; uniform stirring is performed to obtain oil liquid; water is added into the oil liquid; a stirring machine is used for stirring to obtain a mixed coarse emulsion; then, the mixed coarse emulsion is subjected to ultrasound and high pressure microjet homogenization treatment to obtain the water-in-oil nanoemulsion. The basic physical characteristics such as the transparency and the viscosity of grease are not changed; meanwhile, the conditions are created for the use of a water-soluble antioxidant in the grease. The water-in-oil nanoemulsion prepared from a food surfactant of PGPR is applicable to industries such as functional food, medicine, advanced cosmetics and biological products. The preparation method is simple; no pollution exists; the cost is low; the additional values of grease processing industry can be improved; meanwhile, the healthy development of grease related industry is favorably driven.

Description

Technical field [0001] The invention relates to a preparation method of an emulsion, in particular to a preparation method of a water-in-oil nanoemulsion. Background technique [0002] Polyunsaturated fatty acids (PUFA) in oils and fats, also called polyene fatty acids, refer to fatty acids with a chain length of more than 18 carbon atoms and two or more unsaturated double bonds. Among them, fatty acids containing two and three unsaturated double bonds include eighteen-carbon linoleic acid and linolenic acid, which are mostly distributed in vegetable fats; more than four double-bonded polyunsaturated fatty acids are mostly found in marine animal fats. in. Their long chains and multiple cis double bonds with spaced locations give them special structural and physiological functions. In the body, they are not only components of cell structure, but also important for regulating physiological functions. In recent years, people have found that eating more saturated fats can cause hi...
