Groundnut oil has attained the status of cooking medium of choice due to its embedded health benefits. Apart from its alluring strong aroma and universally liked peanut flavor, the all-purpose cooking oil brings multiple health benefits to the table. By being an active agent in lowering cholesterol and especially the bad cholesterol, it is being accepted gleefully across the globe. The benefits include a low content of saturated fat that is naturally free from cholesterol and trans fat. It is further blessed with high unsaturated fat while being a good source of phytosterols and vitamin E. With an assured market and greater possibility of returns, setting up a groundnut oil manufacturing plant for Groundnut oil refining today makes eminent sense.

Methodology of Refining
Groundnut oil is usually refined by alkali neutralization process.
For alkali refining following processing step takes place:
Alkali Refining Process
Bleaching of Groundnut Oil
“Bleaching” is a process of selective removal of pigments and impurities by the physical and chemical interaction of an adsorbent with an oil or fat to improve its quality.
This process refers to the art of removing-
Mectech provides wet bleaching process in its Groundnut Oil Processing Plant which has shown better results with lesser amount of bleaching clay.
Deodorization of Groundnut Oil
Deodorization of Groundnut oil is a vacuum stripping process in which a given amount of a stripping steam is passed for a given period of time through hot oil at a low pressure which removes various volatile components and fatty acids to increase the self-life, and maintained the good odour free test of product.
Deodorization is a Multi-Step Process Comprising
