Oxidation stability of fatty acid methyl esters (FAME) and vegetable oils as per EN 14112 or EN 15751

What are fatty acid methyl esters (FAME)?

Fatty acid methyl esters are usually obtained from oil seeds. During manufacture the vegetable oil is transesterified with methanol. This produces the methyl esters of the fatty acids present in the oil with glycerol as a byproduct.

Quality criterion for biodiesel and vegetable oils

Vegetable oils and fatty acid methyl esters have a relatively short storage life as they are slowly oxidized by atmospheric oxygen. The resulting oxidation products can damage vehicle motors. For this reason the oxidation stability is an important quality criterion for biodiesel and vegetable oils and must therefore be checked regularly during manufacture and storage. With the 873 Biodiesel Rancimat this determination can be carried out simply and reliably. The addition of suitable antioxidants slows down the oxidation process. The effectiveness of antioxidants can also be determined with the 873 Biodiesel Rancimat.

Oxidation stability measurement by Metrohm

The 873 Biodiesel Rancimat is a modern, PC-controlled instrument for the convenient determination of the oxidation stability of oils and fats. The temperature can be set very accurately and reproducibly by using the GLP Set with a certified temperature sensor. This further improves the precision of the results.
