角閃石を含む花こう斑岩は、食用油に対して良好な抗酸化作用を示し、これを食用油と接触させることによって食用油が再生され、食用油の劣化が抑制される。 The granite porphyry containing amphibole exhibits excellent anti-oxidation action on edible oil, by allowing the granite porphyry containing amphibole to contact with the edible oil, the edible oil is recovered and the deterioration of the edible oil is suppressed. - 特許庁
