Glyceridic composition

Glyceridic composition analysis determines the distribution of triglycerides in a fatty substance, based on the nature of the fatty acids and their position on the glycerol molecule (sn-1, sn-2, sn-3). This analysis is essential for characterizing oils and fats of plant or animal origin, and for assessing their nutritional quality, stability, or technological behavior. It is particularly useful in the food, nutraceutical, and functional ingredient sectors.

The reference method is based on gas chromatography (GC) or high-performance liquid chromatography (HPLC), often after transesterification or enzymatic separation. The analysis makes it possible to identify the majority triglyceride profiles (PPP, POP, OPO, etc.), to detect oil mixtures, or to assess the potential digestibility of fats via the position of unsaturated fatty acids.

Typical matrices include: vegetable oils (palm, sunflower, rapeseed, olive, etc.), animal fats, lipid ingredients, milk and infant formulas, butters and margarines.

At YesWeLab , we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the analytical techniques or methods required.
