Marine fish fortification microcapsule aqueous solution agent and preparation method thereof

The invention discloses a marine fish fortification microcapsule aqueous solution agent and a preparation method thereof. The method for preparing the marine fish fortification microcapsule aqueous solution agent comprises the following steps of: (1) dissolving emulsification type isolated soy protein and malto dextrin into distillated water and stirring to obtain emulsified liquid as a wall material; (2) mixing refined tuna oil, lecithin, dunaliella extract, vitamin A, vitamin C, vitamin D3 and vitamin E and stirring the mixture into a core material; and (3) stirring and emulsifying the wallmaterial and the core material, and homogenizing at high pressure to obtain a micro drop emulsified liquid with the granular diameter of 1-200 micrometers, that is to say, the marine fish fortification microcapsule aqueous solution agent. In the invention, the core material which has certain efficacy and is incompatible with water is coated by the wall material to obtain a microcapsule; and the microcapsule is dispersed i
