Analysis of Trans Fatty Acid Content in Processed Foods and Meat Products

초록/요약

Small amounts of trans fatty acids exist naturally in beef and dairy foods. Also, they can be produced in the process ofpartial hydrogenation to manufacture shortning or margarine. They can provide a better palatability and shelf life. Accord-ing to the recently studies, trans fatty acids can raise health risk such as heart diseases and coronary artery diseases. Theycan also increase low-density lipoprotein (LDL) cholesterol and decrease high-density lipoprotein (HDL) cholesterol in theblood plasma, therefore increasing the risk of atherosclerosis aids and trans fatty acids (TFAs) content in processed foods and meat products. The analysis of trans fatty acids was per-formed in 28 samples of donuts, 18 samples of bakeries, 4 samples of frozen doughs, 2 samples of popcorns, and 4 samplesof meat products (ham, sausage, nuget, and bacon). Total lipids in processed foods and meat products were extracted bychloroform-Methanol method and acid digestion, respectively. They were analyzed by gas chromatography using a SP-2560column and flame ionization detector. The amounts of TFAs per 100 g of foods were 0-3.3% (0.74% on average) in donuts,0.2-5.8% (1.18% on average) in bakeries, 0.2-6.3% (1.93% on average) in frozen doughs, and 0-5.8% in popcorns. Meatproducts such as ham, sausage, and nuget analyzed 0.1% of TFAs, respectively and trans fatty acids in bacon were notdetected. facturers and types of products, whereas the content of TFAs in meat products ranged from 0 % to 0.1%.
