Soft candy without fishy taste or odor and preparation method thereof

A preparation method of a soft candy without a fishy taste or odor, comprising the following steps:

• (1) preparation of a docosahexaenoic acid (DHA)-containing mixture, comprising mixing and stirring a DHA-containing raw oil, a fragrance, and an antioxidant, and allowing a resulting mixture to stand to obtain the DHA-containing mixture, wherein in step (1), the mixing and stirring is conducted at 10° C. to 35° C.;
• (2) preparation of an oxygen-isolation preprepared solution, comprising mixing a polymeric sugar, an emulsifying agent, and water, and subjecting a resulting mixture to dispersion with a shearing device to obtain the oxygen-isolation preprepared solution, wherein in step (2), the dispersion is conducted at 30° C. to 90° C., and a rotational speed of the shearing device is 1,000 rpm to 6,000 rpm;
• (3) preparation of an oxygen-isolated DHA-containing solution, comprising adding the oxygen-isolation preprepared solution and the DHA-containing mixture to a dispersion device to allow dispersion, and allowing a resulting system to undergo equilibrium and stabilization to obtain the oxygen-isolated DHA-containing solution, wherein in step (3), the dispersion is conducted for 10 min to 60 min, and the equilibrium and stabilization is conducted for 0.5 h to 3 h;
• (4) preparation of a pigment solution and an acid solution;
• (5) preparation of a syrup;
• (6) preparation of a sugar-containing slurry, comprising mixing the syrup, the oxygen-isolated DHA-containing solution, the acid solution, and the pigment solution to obtain the sugar-containing slurry;
• and
• (7) pouring, comprising pouring the sugar-containing slurry into a soft candy mold for shaping to obtain the soft candy without the fishy taste or odor.
