The preparation method includes: (1) mixing and stirring a DHA-containing raw oil, a fragrance, and an antioxidant, and allowing a resulting mixture to stand to obtain a DHA-containing mixture; (2) mixing and dispersing a polymeric sugar, an emulsifying agent, and water to obtain an oxygen-isolation preprepared solution; (3) dispersing the oxygen-isolation preprepared solution and the DHA-containing mixture, and allowing a resulting system to undergo equilibrium and stabilization to obtain an oxygen-isolated DHA-containing solution; (4) preparation of a pigment solution and an acid solution; (5) preparation of a sticky syrup; (6) mixing the sticky syrup, the oxygen-isolated DHA-containing solution, the acid solution, and the pigment solution to obtain a sugar-containing slurry; and (7) pouring the sugar-containing slurry into a soft candy mold to obtain the soft candy without a fishy taste or odor.
