Abstract
Chlorophylls, tocopherols, and phenolic compounds are fluorescent substances found in vegetable oils. As a result, fluorescence analysis can be used to authenticate vegetable oils in a simple, effective, and non-destructive manner. The goal of the study was to determine the authenticity of vegetable oil using smartphone-based image analysis in fluorescence light. The image was taken with a Huawei P30 Lite and saved as an 8-bit JPG file. Mactronic PHH0062 390 nm-LED flashlight was employed as a light source. Due to the Hue spectral histograms, the image was analyzed in the HSV (Hue, Saturation, Value) color model. Eleven vegetable oils were chosen for testing: sea buckthorn, sunflower, rice, macadamia nut, hemp, corn, grape, linseed, rapeseed, olive, and milk thistle. Because vegetable oils have a diverse Hue spectrum, fluorescence examination can be used to verify their authenticity.
