Elaidic Acid Analysis Service

Online Inquiry

Elaidic acid (9-octadecenoic acid, trans-oleic acid) is a trans fatty acid commonly found in hydrogenated vegetable oils. The dangers of trans fatty acids are becoming more and more well known.

The formation mechanism of trans fatty acids also varies. The trans fatty acids in food mainly come from the fatty acids with trans structures formed during the metabolism of ruminants and during food processing. The trans fatty acids in ruminants are formed by the enzymatic hydrogenation of the hydrogenating bacteria-Vibrio butyricum. In the hydrogenation process of vegetable oil, the trans isomer is produced in the presence of metal catalysts. Under high cooking conditions (150° or higher) oleic acid isomerizes to form elaidic acid.

TFA increases total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) levels and decreases HDL-C levels. 9t-C18:1 has also been shown to induce apoptosis in endothelial cells and human hepatocellular carcinoma cells.

In order to better promote research on disease mechanisms, master the content of trans-oleic acid in various foods and products, and accelerate research in the direction of human health, Creative Proteomics has established a liquid chromatography-mass spectrometry (LC-MS) detection platform for the qualitative and quantitative determination of elaidic acid. In addition, we offer other fatty acid assays to meet your different needs.
