Patent

CA 2717143

Herein are disclosed methods and devices for evaluating the quality of oils (e.g., cooking oil or flying oil). The methods can provide an indication of the free fatty acid content of the oil. The methods use an optical interrogation device to provide an indication of free fatty acid based on quantitative measurements of optical reflectance from test zones on a sampling substrate.

La présente invention concerne des procédés et des dispositifs pour évaluer la qualité dhuiles (par ex., huile de cuisson ou huile de friture). Les procédés peuvent donner une indication de la teneur en acides gras libres de lhuile. Les procédés font appel à un dispositif dinterrogation optique pour donner une indication de lacide gras libre en se basant sur des mesures quantitatives de la réflexion optique dans des zones tests sur un substrat déchantillonnage.
