The invention belongs to the technical field of food processing and discloses a coconut juice pudding which is formed at the room temperature and has an original taste and a preparation method thereof. The coconut juice pudding with the original taste is prepared from 30-45% of coconut pulp, 20-30% of milk, 3-3.5% of gelatin, 0.4-0.5% of gella gum, 0.2-0.3% of modified citrus pectin, 0.02-0.05% ofpreservative, 5-12% of sweetening agent and the balance water. The gelatin, the gella gum and the modified citrus pectin are added into water for swelling and heating to obtain compound gel; the coconut pulp and the milk are mixed and then heated to 90-100 DEG C to obtain a milk-based mixed solution, then the compound gel is added into the milk-based mixed solution and stirred, the sweetening agent and the preservative are added, and the mixture is sequentially subjected to homogenization, sterilization and cooling until forming at the room temperature to obtain the coconut juice pudding withthe original taste. The coconut juice pudding can be solidified, formed and stored at the room temperature, and the usage of the gelatin is obviously reduced.
