Microencapsulation of fish oil can not only realize the uniform dispersion and prevention of oxidation of fish oil, but also conceal fishy odor, improve digestibility and expand the scope of application. The development status of microencapsulation of fish oil and microencapsulation methods suitable for fish oil were introduced, including spray drying method, complex coacervation method, molecular inclusion method, freeze drying method, tiny hole and solidifying bath method and liposome embedding method. The impact factors of spray drying preparation of fish oil microcapsule on embedding rate were mainly introduced, including physical and chemical properties of wall material, solid concentration, emulsification method and emulsification conditions (temperature, pressure, frequency) and spray drying conditions (inlet and outlet air temperatures). The development direction of microencapsulation of fish oil was prospected. |
