Edible Fats and Oils Analysis

Edible fats and oils play an important role in the human diet because of their nutritional characteristic, organoleptic, heat transfer and rheological properties. And they are the source of high energy and essential fatty acids such as linoleic and linolenic acids. The chemical constituents of fats and oils are triglycerides, such as esters of glycerol and three fatty acid molecules. The physicochemical properties of fats and oils are principally determined by the type and the number of triglycerides they contain and their thermal and shear histories. The physical and chemical properties of edible fats and oils can affect the quality of oil foods and hence must be evaluated in detail.
