Comprehensive analysis of FAMEs, fatty acids, and triglyceridesAgilent J&W GC columns for food nutrition testing

2

To optimize processing, taste, texture, and shelf life, you must thoroughly test the oils and fats that go into your products.

The most common analytical methods rely on indirect GC analysis of free fatty acids or fatty acid methyl esters (FAMEs). Direct analysis of triglycerides—as well as mono- and diglycerides—also provides insights into fat and oil characterization, and can be paired with the analysis of cholesterol and other lipids.

Agilent J&W GC columns for fat and oil analysis are developed and tested for qualitative and quantitative analysis of FAMES, free fatty acids, and triglycerides. Our comprehensive, innovative column portfolio enables you to achieve fast, accurate, and reproducible separations for both simple and complex samples.

This easy-reference guide will help you select the right column for your application. It includes:

– Detailed chromatograms and analytical conditions

– Column specifications

– Selection charts based on specific analytes

Maintain the highest standards for product content, quality, and purity

Why is fatty acid and oil analysis important and how does it impact consumers?Tests Run by Food Testing Labs (under ‘Nutrition Label Testing’)

– Fat Profile (Total Fat, Saturated Fat, Monosaturated Fat, Trans Fat from Fatty Acids

– Free Fatty Acids

– Omega 3 Fatty Acids

– Omega 3, 6 Fatty Acids

Accurately determining total fat content is critical to complying with food identity and nutritional labeling laws.

The new DB-FATWAX Ultra Inert is designed for the separation of fatty acid methyl esters (FAMEs), fatty acid ethyl esters (FAEEs) and fatty acids. This column is tested with a FAME mixture to ensure reproducible FAME equivalent chain length (ECL) values, proper identification of important FAMEs such as EPA, DPA and DHA, and resolution of key pairs of FAMEs. Because of Agilent’s proprietary Ultra Inert technology, DB-FATWAX UI is the only WAX-type phase that is able to offer symmetric peaks for even challenging polar compounds such as free fatty acids. This feature improves inertness, thermal stability and column life time compared to traditional WAX columns.

Agilent J&W DB-23: Fast separation of saturated/unsaturated FAMEs and key cis/trans isomers DB-23 is a traditional 50% cyanopropyl column that is slightly less polar than high-content cyanopropyl columns such as HP-88 and CP-Sil 88 for FAME, but with similar intermolecular forces, keeping similar interactions between stationary phase and analytes. With DB-23, it is possible to reduce the analysis time for FAME analysis, with good resolution even for challenging cis/trans FAME isomers. In this chromatogram, we show the separation of a typical mix of nutritional labeling FAMEs under 8 minutes including C18:1 and C18:2 pairs, and popular FAMEs commonly found in milk fat, vegetable oil, and fish oil, including DPA, and EPA.

This column is also tuned for optimal cis/trans FAMEs analysis, especially the C18 isomers. This low-bleed, bonded column has an isothermal maximum operating temperature of 275 ºC and a programmed temperature of 290 ºC, a dramatic improvement of 50 ºC compared to non-bonded columns. These features also make this column ideal for GC/MS applications on FAMEs. Columns up to 200 m are available for detailed analysis of the C18:1 isomer cluster. Select FAME also offers three times greater loadability, further improving the shape and separation for FAME isomers.
