Preparation method of peony seed powdered oil containing active peptides

The invention belongs to the technical field of oil processing and, in particular, relates to a preparation method of peony seed powdered oil containing active peptides. The preparation method includes the steps of 1, dissolving a wall material and active peptides with distilled water, and performing heating and stirring to obtain solution A; 2, adding functional food factors and an emulsifying agent into peony seed oil, and performing uniform mixing to obtain emulsion; 3, subjecting the emulsion obtained in the step 2 to shearing emulsification to obtain emulsified solution; 4, adding the solution A obtained from the step 1 into the emulsified solution obtained in the step 3, and performing high-pressure homogenization to obtain solution B; and 5, spraying and drying the solution B obtained in the step 4 so as to obtain the peony seed powdered oil containing the active peptides. According to needs of different special people, different nutrients are compounded to the peony seed powdered oil prepared by the preparation method, the peony seed oil having high Alpha-linolenate content has high nutritional value, and the powdered oil without cane sugar is suitable for patients with high blood glucose and diabetics.
