Abstract

The invention provides a preparation method of water-in-oil nano-emulsion. The preparation method comprises the following steps of: adding polyglycerol polyricinoleate to liquid raw oil; uniformly stirring to obtain oil; adding water to the oil; stirring through a stirring machine, thus obtaining mixed coarse emulsion; and then processing the mixed coarse emulsion in a way of ultrasonic high-pressure micro-jet homogenizing, so as to obtain the water-in-oil nano-emulsion. By adopting the preparation method, the basic physical characteristics of grease are remained, such as transparency and viscosity; simultaneously, a condition is created for using a water-soluble antioxidant in the grease. The water-in-oil nano-emulsion, prepared through a food surface active agent which is the polyglycerol polyricinoleate, is suitable for being applied to the industries of foundational foods, drugs, high-level cosmetics, biological products, etc. The preparation method is simple, free of pollution and low in cost, can improve the additional value of the grease processing industry, and is beneficial for prompting the healthy development of industries related to the grease.

Description

technical field [0001] The invention relates to a method for preparing an emulsion, in particular to a method for preparing a water-in-oil nanoemulsion. Background technique [0002] Polyunsaturated fatty acids (PUFA) in oils and fats are also called polyene fatty acids, which refer to fatty acids with a chain length of more than 18 carbon atoms and containing two or more unsaturated double bonds. Among them, fatty acids containing two and three unsaturated double bonds are octadecyl linoleic acid and linolenic acid, which are mostly distributed in vegetable oils; polyunsaturated fatty acids with more than four double bonds are mostly found in the fat of marine animals middle. Their long chains and multiple cis double bonds positioned at intervals endow them with special structural and physiological functions. In vivo, they are not only components of cell structure, but also important in regulating physiological functions. In recent years, people have found that eating mo...
