Abstract The present invention discloses a method of layer-by-layer self-assembly immobilizing flaxseed oil and a composite oil thereof. The method comprises 5 the following steps: (1) dispersing the oil in a sodium alginate aqueous solution, and obtaining oil-sodium alginate microcapsules through shearing or homogenizing; (2) adding the oil-sodium alginate microcapsules into a calcium lactate aqueous solution, and obtaining immobilized oil-sodium alginate gel beads through stirring; (3) sequentially adding the immobilized 10 oil-sodium alginate gel beads into a chitosan aqueous solution, the sodium alginate aqueous solution and the calcium lactate aqueous solution, sequentially stirring, and obtaining a layer of self-assembly immobilized oil-sodium alginate gel beads; (4) repeating step (3) with the layer of self-assembly immobilized oil-sodium alginate gel beads, i.e. realizing the 15 layer by layer self-assembly immobilizing of the oil. The gel beads of the present invention has a high oil-loading rate, and when being calculated according to the mass ratio of a core material and a wall material, the oil-loading rate of the microcapsules in the present invention is up to 1700-7000%. The method of the present invention can be carried out under 20 room temperature, and the temperature required is lower than that required in the method of spray drying, thereby saving the cost.
