Featured Applications
 

Analytical testing is used in the production of worldwide food supply. This testing primarily serves two purposes: to determine nutritional value and quality, and to guarantee safety. Sigma-Aldrich®, through its Supelco® brand, is very active in product development for food and beverage analysis.

Food Chemistry

Many food companies are currently and may soon to be under more pressure from the Food and Drug Administration to make their foods healthier. Since 2006, the FDA indicates requirements to include trans-fat content on nutritional labels. However, they are often, but not always, found in products.(source)

In the following application, our scientists developed a procedure to determine trans-fat levels in foods. This procedure involves extraction, derivatization, fractionation and GC analysis.

 

Comprehensive Determination of Trans Fats in Cookies

Using Silver-Ion SPE Fractionation, SP™-2560 and SLB®-IL111 GC Columns …more

1. Silverion (Ag-ion) fractionation is applied to the FAMEs to separate the saturates and C18 trans monoenes in fraction 1, the cis monoenes in fraction 2, and the dienes in fraction 3.

2. GC analysis of each fraction is then performed on an ionic liquid GC column. This extremely polar GC capillary column was the world’s first commercial column to rate over 100 on our GC column polarity scale. As such, it has the most orthogonal selectivity compared to commonly used non-polar and intermediate polar columns, providing increased selectivity for polar and polarizable analytes. The 100 m version is a great complementary column to the SP-2560. …more

Ionic Liquid Capillary Columns for the Analysis of FAME Isomers

Analyses of fatty acid methyl esters (FAMEs) are continuing to gain importance as more research is focusing on their biomedical impacts. Our two new phases are SLB®-IL60 with a PEG like selectivity and the SLB-IL111 with highly polar selectivity. We will compare and contrast the selectivity of the ionic liquid phases with polymeric based phases for various FAME samples. …read more on SLB®-IL60 and SLB-IL111
