< Topic > Eating quality of prevention and the fried food of oxidation of the heaven pu and others oil, it adjusts to the improvement of the food impression, for decreasing the amount used and the energy quantity of the heaven pu and others oil, it offers the oxidation prevention material and oxidation prevention method of the heaven pu and others oil which uses the tourmaline. Solutions This invention, the tourmaline minute powder, in the blend calcination body of the excited material fines and the electric high resistor fines by the fact that the ceramics which the precious metals the surface was processed is used, made that oxidation of the heaven pu and others oil is prevented with the active hydrogen of the reducing agent which is formed by the tourmaline, possible as an expedient of prevention of oxidation of the heaven pu and others oil. < Selective figure >Figure 1【課題】 天ぷら油の酸化防止、揚げ物の食味、食感の改善と併せ、天ぷら油の使用量やエネルギー量の低減のため、電気石を用いる天ぷら油の酸化防止材および酸化防止方法を提供する。【解決手段】 本発明は、天ぷら油の酸化防止の手段として、電気石微細粉、励起材微粉、電気高抵抗体微粉の混合物焼成体に貴金属類を表面処理したセラミックを用いることで、電気石により生成される還元剤の活性水素によって、天ぷら油の酸化を防止することを可能にした。【選択図】図1
