The invention provides a preparation method of regenerated cellulose stabilized citral Pickering emulsion. The preparation method comprises the following steps: taking microcrystalline cellulose available in the market as a raw material, performing phosphoric acid dissolution treatment, diluting with water to regenerate, and washing with water to obtain regenerated cellulose suspension liquid; freeze-drying the suspension liquid to obtain regenerated cellulose powder; and dispersing the regenerated cellulose powder into a citric acid-sodium citrate acidic buffer solution with the pH value being 3 to form regenerated cellulose suspension liquid, adding citral and medium chain triglyceride into the above suspension liquid, and homogenizing at high speed to obtain stable citral Pickering emulsion. The citral Pickering emulsion prepared by the method has the characteristics of small use amount of regenerated cellulose, simple preparation process, environmental friendliness, low applicationcost and the like, and c
