Disclosed are a soft capsule and a preparation method therefor. A DHA oil composition contains a DHA oil, wherein the DHA oil contains DHA and EPA. Where suitable subjects for the soft capsule are pregnant and parturient women, infants and young children and teenagers, the content ratio of DHA to EPA is greater than 12:1; and where suitable subjects for the soft capsule are middle-aged and elderly people, the content ratio of DHA to EPA is not more than 8:1. The preparation method comprises: mixing water, gelatin powder and glycerin and subjecting same to a sol process to obtain a sol mixture; and pouring the above-mentioned DHA oil composition into the sol mixture to obtain a soft capsule. The method can prepare a DHA soft capsule suitable for different populations, and can also effectively slow down the oxidation of the oils, reduce the anisidine value, peroxide value and acid value, control the color change of a soft capsule, and increase the storage time of a DHA oil soft capsule.
