  Working Principles
Click to ViewThe Rancimat method is an accelerated aging test. Air is passing through the sample in the reaction vessel at constant elevated temperature. In this process fatty acids are oxidized. At the end of the test volatile, secondary reaction products are formed, which are transported into the measuring vessel by the air stream and absorbed in the measuring solution (deionized water). The continuously recorded electrical conductivity of the measuring solution is increasing due to the absorption of the reaction products. Thus their appearance can be detected. The time until secondary reaction products are detected is called induction time.

  User Instructions
1. It characterizes the oxidation stability of oils and fats. 2. Indicates shelf-life of fat rich food products. The Rancimat method is included in various national and internationals standards, such as: AOCS Cd 12b-92 (AOCS – American Oil Chemists’ Society) Sampling and analysis of commercial fats and oils: Oil Stability Index, ISO 6886 Animal and vegetable fats and oils – Determination of oxidation stability (accelerated oxidation test), Fat stability test on Autoxidation.
