A ceramic sphere for preventing deterioration of fats and oils which may be prepared by a method comprising admixing a fine metal oxide powder comprising 35 to 55 mass % of silicon oxide, 25 to 45 mass % of aluminum oxide, 2 to 8 mass % of ferric oxide, 1 to 5 mass % of titanium oxide and 1 to 5 mass % of magnesium oxide and having a particle diameter of 200 to 300 meshes, with 3 to 8 mass % of a fine power of calcareous ovolite obtained by burning a raw material at 1700 to 1800 DEG C and then pulverizing to a particle diameter of 200 to 300 meshes and 5 to 15 mass % of a clay mineral or a mixture of clay minerals comprising five or more selected from among iron (Fe), manganese (Mn), titanium (Ti), calcium (Ca), magnesium (Mg), aluminum (Al), silicon (Si), potassium (K) and sodium(Na) and having a particle diameter of 200 to 300 meshes, adding water to the resultant admixture, followed by kneading, forming and drying, and then burning the dried, formed product at a temperature of 1500 DEG C or higher; and an apparatus for preventing deterioration of fats and oils using the ceramic sphere.
