The invention relates to a storage method of non-edible animal and vegetable oil. According to the invention, a composition comprising 20% of a lactone compound, 50% of a hindered phenol compound and 30% of a sulfur-containing synergistic agent is added into the non-edible animal and vegetable oil. With the method, the quality of non-edible animal and vegetable oil during a biological aviation kerosene/biodiesel processing enterprise production period can be effectively maintained; and the rancidity degree of the oil during a storage period can be reduced. The method facilitates the popularization of biological aviation kerosene/biodiesel with non-edible animal and vegetable oil as a raw material.
