Edible oil having excellent storage stability, and method for production thereof

Abstract

Disclosed is an edible oil which is hardly deteriorated by oxidation and therefore has excellent storage stability. Also disclosed is a method for producing the edible oil. A nitrogen gas in the form of nanobubbles each having a diameter of less than 1000 nm (1 μm) and microbubbles each having a diameter of 1 to 350 μm (inclusive) is added to an edible oil. In this manner, it becomes possible to produce an edible oil having a content of nitrogen in the oil or a content of dissolved nitrogen in the oil of 4.5% (by volume) or more and an edible oil containing nitrogen nanobubbles each having a diameter of less than 1000 nm (1 μm) and nitrogen microbubbles each having a diameter of 1 to 350 μm (inclusive).

Dependencies are inferred from the claim text.
