Reagent for trans-Fatty Acid Analysis

trans-Fatty acids are contained in margarines and shortenings produced by hydrogenating vegetable oils, also meats and dairy products in naturally derived foods. In recent years, prevention and improvement of obesity and lifestyle-related diseases caused by excessive lipid intake have been promoted from the perspective of trans-fatty acid intake and the risk of heart disease. In Japan, dietary guidelines pay attention to the balance between lipid intake and fatty acid type intake. In other countries, labeling of saturated fatty acids and trans-fatty acids in processed foods is obligatory, and standard values are set for trans-fatty acid concentration in foods.
FUJIFILM Wako provides variety of triglycerols and methyl esterifying agents composed of various saturated fatty acids and various fatty acid methyl esters.

Internal Reference Material

Analytical methods for trans-fatty acids include the AOCS Official Method (AOCS Ce1h-05) and AOAC International Method (AOAC 996.06). Triheneicosanoin (a triglyceride composed of saturated fatty acids, with 21 carbon atoms; C21:0) is described as an internal reference material for quantification by the AOCS method, and triundecanoin (C11:0) is described as an internal reference material for the quantification of trans-fatty acids by the AOAC method. Heptadecane acid methyl ester (C17) is used as the internal reference material for for vegetable oils and animal fats analysis in the standard methods for the analysis of fats, oils and related materials set by the Japan Oil Chemists’ Society. In addition to the above standard products, FUJIFILM Wako provides an array of triglycerides composed of various saturated fatty acids.
