665.0288 AOCS 7th ed. 2017-2019 rev. Ref.
A homogenized test portion of crude fat or oil is allowed to stand at a controlled temperature for a period of 96 h. The volume of separated material, called “visible foots,” is read off from the graduated vessel. “Visible foots” refers to the insoluble matter in fats and oils, together with occluded oil, which settles out from oil or fat within 96 h at the temperature specified in this method. This method specifies a method for the determination in crude fats or oils of visible matter which can be separated by gravity.
