Quantitative Measurement of Trans-Fats by Infrared Spectroscopy
Edward B. Walker, Don R. Davies, and Mike Campbell
Department of Chemistry, Weber State University, Ogden, UT 84408-2503

July 2007
Vol. 84 No. 7
p. 1162
Abstract
Over the past decade, the trans-fat content of foods has become increasingly important to consumers. FTIR-ATR spectroscopy provides an efficient analytical tool to measure the percentage of trans-fat in several commercially available lipids. Instrument calibration is easily established using pure cis and trans isomeric standards. The degree of alkene isomerization induced by bromination–debromination chemical reactions is also determined using this analytical method.
Supplement
Instructions for the students and notes for the instructor are available.
