Edible oils are mostly vegetable based oils which are similar to those produced in biotechnology industry, especially biodiesel and biofuels, but not biocompatible by biotechnology industry. The oils to be used as food can be solid or liquid at room temperature.
Vegetable-derived edible oils are composed of carboxylic acids having no longer carboxyl group and, in contrast to petroleum-based oils, having more long hydrocarbon chains.
