The shortening Brazilian market has wide range of products for specific use, mainly at industrial level. In the present work 19 samples of shortenings, 14 samples of margarines and 9 samples of spreads were studied. Iodine index, softening point, trans fatty acids, solid fat content and fatty acid composition were determined in all samples. High levels of trans fatty acids in most of the samples were observed (30%), varying between 0-62%. Correlations for thermal characteristics of the samples between the fat groups were not found. In Brazil most of shortenings are produced for blends of soy bean oils with different level of hydrogenation.

2005: I understood that trans fat should be avoided because it can increase your risk of cardiovascular disease. And I had heard that the main source of trans fat is partially hydrogenated oils. Now, I see some products contain partially hydrogenated vegetable oils but still claim to be trans-fat free. How is this possible? Mayo Clinic Health Letter 23(4): 8
