Problems solved by technology

There have been many products that use ovalbumin as an emulsifier. First, the raw materials are easy to obtain and the cost is low. Second, its foaming properties can also be used in products, but there are also the following: (1) Ovalbumin due to its water solubility Poor emulsification activity and emulsification stability of the emulsion are poor; (2) Due to poor emulsification properties, a large amount of other substances need to be added to maintain system stability, which greatly shortens the shelf life of the product; (3) Due to the presence of shells formed between protein macromolecules Due to the large gap, the shell structure is thin and unstable, and demulsification is easy to occur
(4) The choice of shell structure only considers that it is harmless to humans or animals, and does not further consider the deep health care effect

Abstract

The invention discloses a preparation method of an ovalbumin emulsion having a double-shell structure. A purpose of the present invention is to solve the problems of to-be-improved shell-core stability and insufficient emulsifying property of the existing ovalbumin emulsion. The technical scheme comprises: (1) dissolving ovalbumin in water, carrying out magnetic stirring dissolving, adding inulin,and carrying out ultrasonic treatment to obtain an ovalbumin-inulin solution; (2) adding an oily core material to the ovalbumin-inulin solution, placing under a high-speed shearing device, shearing,and carrying out high-pressure micro-jet homogenizing a plurality of times to obtain an emulsion; (3) loading the iron ions of ferrous fumarate onto the surface of the emulsion droplet of the emulsionby using an ion exchange method to obtain a mixed solution, adjusting the pH value of the mixed solution, and carrying out centrifuging concentrating to obtain a concentrated emulsion; and (4) addingdisodium stannous citrate to the concentrated emulsion, and stirring at a low speed to obtain the ovalbumin emulsion. According to the present invention, the process is simple, the double-shell corestructure is stable, the emulsifying activity and the emulsifying stability of ovalbumin are substantially improved, and the ovalbumin emulsion has health effect, and further has good storage stability.

Description

technical field [0001] The invention relates to an ovalbumin emulsion, in particular to a method for preparing the ovalbumin emulsion with a double-shell structure. Background technique [0002] Emulsion, also known as emulsion and emulsification, refers to a heterogeneous liquid dispersion system formed by one phase liquid dispersed in another phase liquid in the state of tiny droplets. It is a relatively traditional and widely used industrial technology raw material or product , can be widely used in cosmetics, construction, chemical, food and other fields. The principle is to make two immiscible liquids shake to form a dispersion system. In order to ensure the stability of the dispersion system, emulsifiers are often added, such as phospholipids, choline, proteins, polysaccharides, etc. At present, the emulsifying and foaming properties of ovalbumin (OVA) are widely used in food, cosmetics, paint and other industries. It is well known that the emulsification and stabilit...
