Animal and vegetable fats and oils — Determination of the composition of fatty acids in the 2-position of the triglyceride molecules. 90.93 · 67.200.10 Fatty acid composition is useful to detect adulteration of olive oil with the following vegetable oils including soybean, walnut, canola, rapeseed, peanut and Coconut oil is also high in saturated fat, but it has a different structure than saturated fats found in animal products. Coconut oil has become popular due to its Individual triglycerides differ in physical properties according to their fatty acid composition. Thus, when a fat is kept at a particular tempera- ture those triglycerides Fats and oils are composed of molecules known as triglycerides, which are esters composed of three fatty acid units linked to glycerol. An increase in the percentage of shorter-chain fatty acids and/or unsaturated fatty acids lowers the melting point of a fat or oil. Depending on the type of fatty acid, the chemical structure of fat varies. Also, the properties of any fat vary with the fatty acid. Fat molecules are trimesters of glycerol which are known as triglycerides. Therefore, fats have ester bonds. Fats can be categorized into two as saturated and unsaturated fats. Generally speaking, oils containing a greater proportion of unsaturated fatty acids are liquid at room temperature whereas those with higher amounts of saturated fatty acids will be solid. The Chemical Structure of Fatty Acids Fatty acids are either saturated or unsaturated.

5 Jun 2015 This paper evaluated FAs composition of some vegetable oils, energy contribution E (% ERDI) of saturated (SFAs), polyunsaturated (PUFAs) fatty Olive oil and rapeseed oil are monounsaturated oils. Polyunsaturated fats possess double bonds in their structure. They are less stable to oxidation and are 25 Mar 2014 Zooming in on the molecular structure, how are dietary fats built? the deodorization of vegetable oils/fats, the final step in edible oil/fat refining Among the evaluated oils the higher contents of satu- rated fatty acids were found in palm kernel oil (76.0%. ± 1.95) and coconut fat ( 90.5% ± 2.95) with predom-.
