To provide methods of efficiently producing ceramide (particularly ceramide NP) from a plant.SOLUTION: Provided is a method for producing ceramide comprising subjecting a plant-derived raw material in autophagy induction conditions, comprising at least one step selected from the group consisting of: heating at 30 to 70°C at least one undifferentiated plant-derived raw material selected from the group consisting of undifferentiated plants, dried undifferentiated plants, or crushed undifferentiated plants； crushing the undifferentiated plant derived raw material； and placing the undifferentiated plant-derived material in an oligotrophic state. The step of heating the plant-derived raw material at 30 to 70°C is the step of heating the raw material in the presence of a proteolytic enzyme having activity at 30 to 70°C.SELECTED DRAWING: None【課題】植物からセラミド（特にセラミドＮＰ）を効率よく生産する方法の提供。【解決手段】未分化植物、未分化植物の乾燥物、又は未分化植物の破砕物からなる群から選択される少なくとも一つの未分化植物由来原料を３０～７０℃で熱する工程、前記未分化植物由来原料を破砕する工程、及び前記未分化植物由来原料を貧栄養状態に置く工程、からなる群より選択される少なくとも１工程を含む、前記植物由来原料をオートファジー誘導条件下に供する工程を含む、前記セラミド製造方法。３０～７０℃で植物由来原料を熱する工程が３０～７０℃で活性を有する蛋白質分解酵素の存在下で原料を熱する工程である、方法。【選択図】なし
