  • Process for determining the smoke content of edible oil
    Patent number: 5849596
    Abstract: The present invention provides a process for determining the smoke content of an edible oil of a given amount, which comprises heating the edible oil to a temperature necessary to generate smoke; collecting the generated smoke by sulfuric acid; and determining the smoke content of the edible oil by colorimetry through comparing the color index of the collected smoke in sulfuric acid with the pre-established calibration function representing the relationship between the color index and concentration of the edible oil smoke in sulfuric acid.
