Edible oils consist of about 96% triacylglycerides, composed of different fatty acids. Some other compounds or groups of compounds, such as free fatty acids, phospholipids, phytosterols, tocopherols, other antioxidants or waxes, can also be found.
What are the main components of fats and oils?
Triglycerides are the predominant component of most food fats and oils. The minor components include mono- and diglycerides, free fatty acids, phosphatides, sterols, fatty alcohols, fat-soluble vitamins, and other substances. A triglyceride is composed of glycerol and three fatty acids.
What are quality components of edible oil?

What is the composition of vegetable oil?
Vegetable oils are mainly triacylglycerols (92–98%), polar lipids (phospholipids and galactolipids), monoacylglycerols, diacylglycerols, and minor amounts of free fatty acids and polyisoprenoids.
What are the three main groups of oil?

What is oil chemistry?
Oil is a wide variety of natural substances of plant, animal, or mineral origin, as well as a range of synthetic compounds. … Crude oils are mixtures of hydrocarbon compounds, volatile compounds and non-volatile compounds.

How are cooking oils made?
Essentially, the vegetable oil production process can be broken down into the following stages: cleaning, pressing, solvent extraction, refining and packaging. Below, we have outlined what these stages entail. Seeds and nuts need to be cleaned and stripped of their extraneous material before being refined into oil.
Is cooking oil a mixture or pure substance?
Examples of homogeneous mixtures include vegetable oil, honey, and air. While these substances contain multiple types of molecules, their composition is consistent throughout a sample. If you add soot to air, it ceases to be a pure substance.
