Edible oils and fats are biological mixtures of plant or- igin consisting of ester mixtures derived from glycerol with chain of fatty acids [1]. Both the physical and the chemical characteristics of oils and fats are greatly in- fluenced by the kind and proportion of the fatty acids on the triacylglycerol [2, 3].

The principal sources of fat in the diet are vegetable fats and oils. meats, dairy products, poultry, fish and nuts. Most vegetables and fruits consumed as such contain only small amounts of fat. Fatty acids are the building blocks of lipids and generally comprise 90% of the fats in foods.

An important quality parameter of edible oils and fats is the fatty acid profile (C16:0, C18:0, C18:1 etc.), since it is a measure of the amounts of individual fatty acids in an oil or fat.

Oils and fats form an important part of a healthy diet. Structurally they are esters of glycerol with three fatty acids (called either triacylglycerols or triglycerides). It is these fatty acids that give the functionality to fats. Chemically, they can be divided into four main types saturated, cis-monounsaturated, cis-polyunsaturated and trans fatty acids. In very broad terms, saturated

Base and acid numbers are crucial for classifying fats and oils as well as fat- and oil-containing products.
