Problems solved by technology

[0005] However, selenized carrageenan has some disadvantages in producing a form suitable for commercialization
For example: 1. Selenized carrageenan is easy to be stained with mold, and some preservatives need to be added to preserve its value, which is not beneficial to users
2. Selenized carrageenan has high water solubility, and the preparation of powder is easy to absorb moisture and agglomerate, which is not conducive to storage and quantitative consumption by users. If it is made into capsules, it will cause softening, dissolution, and powd

Abstract

The invention discloses a preparation method for selenized carrageenan water-in-oil emulsion, and a product and application of the selenized carrageenan water-in-oil emulsion. The preparation method is characterized by comprising the following steps of: (1) dissolving selenized carrageenan into water to form a water phase; (2) heating corn oil and Span 80 on a water bath at temperature of 45 DEG C to form a uniform transparent light yellow solution, adding Tween 80 and uniformly mixing the Tween 80 and the uniform transparent light yellow solution to form an oil phase; (3) keeping the water bath, dropwise adding the selenized carrageenan solution into the oil phase and stirring the mixture into a transparent solution; and (4) detecting a finished product. The selenized carrageenan water-in-oil emulsion prepared by using the method is yellow liquid from the appearance; and after being heated and stirred, the selenized carrageenan water-in-oil emulsion cannot be layered at low temperature, so a user can observe uniform single phases by eyes and a Tyndall effect exists. The selenized carrageenan water-in-oil emulsion can be used as an additive for an oil food or is independently packaged into a capsule which is used as a functional healthy food and marketed. The selenized carrageenan water-in-oil emulsion has the advantages that: the particle size is suitable for living beings, the stability and the compatibility are high, the manufacturing process is simple and the practicability is extremely high.

Description

(1) Technical field: [0001] The invention relates to a development technology in the technical field of marine extract particle design, in particular to a preparation method of selenized carrageenan water-in-oil emulsion and its products and applications. (two) background technology: [0002] Emulsion is a special liquid dispersion system, which is spontaneously formed by water phase, oil phase, surfactant and co-surfactant in an appropriate ratio, and is transparent or translucent, low viscosity, isotropic and thermodynamically stable oil-water Hybrid system. The absorption of drugs in emulsion needs to pass through oil-water film and biofilm, which can play a role in controlling drug release. The particle size of the emulsion is generally between 10 and 100nm, so it is also called nanoemulsion, and can be divided into oil-in-water (O / W) type and water-in-oil (W / O) type. In addition, dissolving unstable drugs in the oil phase or water phase to make nanoemulsions can great...
