23 Jul Preparation method of high oil-carrying emulsion rich in fibrous polysaccharides
Abstract
The invention relates to a preparation method of a high oil-carrying emulsion rich in fibrous polysaccharides. The preparation method comprises the following steps: protein powder is taken and added into distilled water, and is magnetically stirred and dissolved at a normal temperature to prepare a protein solution by hydration in a refrigerator at 4 DEG C; the protein solution and fibrous polysaccharide aqueous dispersion powder are mixed, and the pH value of the system is adjusted to obtain a protein/fiber complex; and an oil phase is dispersed in the protein/fiber complex and emulsificationis performed to prepare an oil-in-water emulsion. According to the preparation method of the high oil-carrying emulsion rich in the fibrous polysaccharides, the protein and fibrous polysaccharide complex is used as an emulsifying stabilizer to synergistically improve the wettability and stability of particles, and proteins and fibrous polysaccharides jointly adsorb on an oil-water interface to form a stable three-dimensional network structure to obtain the viscoelastic and highly stable emulsion. Natural food grade materials are adopted. The preparation process is simple and convenient, no surfactant is added, and green and safety are achieved. The content of the required compound stabilizer is low, and good emulsification stability is achieved. The oil phase and a water phase are removedfrom the prepared oil-in-water emulsion, a porous and stable network structure can be formed, and the high oil-carrying emulsion can be used as a porous polymer scaffold material in tissue engineering.
