Title:

Document Type and Number:

WIPO Patent Application WO/2023/054100

Kind Code:

A1

Abstract:

Provided are an edible oil deterioration degree determination device, an edible oil deterioration degree determination system, an edible oil deterioration degree determination method, an edible oil deterioration degree learning device, and a learned model for use in edible oil deterioration degree determination that make it possible to accurately distinguish the type of surface foam in a frying oil and precisely determine the degree of deterioration of the frying oil.　The present invention is a deterioration degree determination device 5 for determining the degree of deterioration of frying oil Y and includes: an oil surface image acquisition unit 50 that acquires an oil surface image as an oil image; a filter processing unit 53 that carries out filter processing on the oil surface image in which an area of fine bubbles β characterizing deterioration of the frying oil Y is identified on the basis of the color range of bubbles included in the oil surface image; a feature parameter calculation unit 54 that calculates a feature parameter characterizing the deterioration of the frying oil Y; a deterioration index estimation unit 55 that estimates a deterioration index DI for the frying oil Y on the basis of the feature parameter; and a deterioration degree determination unit 56 that determines the degree of deterioration of the frying oil Y on the basis of the deterioration index DI.
