Document Type and Number:
WIPO Patent Application WO/2023/157224
Kind Code:
A1
Abstract:
According to the present invention, there are provided: a contained edible oil in which deterioration in quality prior to an expiration date can be reliably stopped, and which has exceptional storage stability; and a method for producing the contained edible oil. This contained edible oil is produced through a method including: an inert gas ultrafine bubble (UFB) supply step for blowing an inert gas into a post-refinement edible oil until the numeric concentration of UFBs having a grain diameter of less than 1 μm reaches 80,000,000/mL or greater, and setting the oxygen saturation of the oil to 1 mg/L or less; and a head space displacement step for displacing a head space in a container filled with an edible oil obtained through the aforementioned step by using the inert gas. The contained edible oil contains UFBs of the inert gas at a numeric concentration of 80,000,000/mL or greater, and the oxygen saturation of the oil is 1 mg/L or less.
