What will be Coconut Oil Application for Industrial Usage?

Coconut Oil has been used extensively for edible and non-edible purpose around the world. Detergent industries mainly relies on Coconut and Palm Kernel Oil for Lauric Acid. It is in the top of the world's most wanted natural oils for confections, bakery goods, deep fat frying and many non-edible purpose.

A particular usage for coconut oil was as a raw material for the fatty alcohols and the methyl esters, which will be mostly use for detergent manufactured.

Coconut Oil Application can be divided into two major terms as: Edible and Non-edible.

Edible applications of coconut oil

★ Use in the synthesis of mediumchain triglycerides

Medium chain triacylglycerols are unique categories of lipids produced by the esterification of glycerol with medium chain fatty acids, which come from high lauric oils. Coconut and palm kernel oils are the only commercially important sources of medium chain fatty acids. These oils are hydrolyzed to liberate their fatty acids from glycerol, and then the fatty acids are separated by fractional distillation.The lower boiling or top fraction of the fatty acids contains the medium chain acids.The esterification reaction between glycerol and the medium chain fatty acids is carried out at high temperatures with or without use of a catalyst. The water liberated in the reaction is removed continuously to drive the reaction to completion. When the esterification reaction is complete,excess fatty acids are removed from the reaction mixture by vacuum distillation. To remove the volatile odor and flavor components as well as any residual fatty acids, the crude MCTs are deodorized to get a final product that has a bland flavor and is odorless and colorless. 

★ Functional benefits of mediumchain triglycerides

Medium chain triglycerides are widely used in the flavor industries as they are more polar and therefore more hydrophobic and can dissolve variety of polar substances that are insoluble in conventional fats and oils. Hydrocarbons, esters and natural oils as well as alcohols, ketones and acids are miscible with MCTs. These properties make MCTs superior carrier for flavors,vitamins and colors when compared to conventional oils. MCTs have a lower molecular weight than conventional oils. This gives MCTsa lower viscosity than conventional oils, even at low temperatures. MCTs oils have no unsaturated fatty acids present; therefore they are-exceptionally stable to oxidation. MCTs have excellent keeping qualities and therefore help to increase shelf- life of finished products. MCTs are ideal for treating the surfaces of crackers toact as a moisture barrier. They adhere well to surfaces, including metals. They are excellent release agent for surfaces that come into contact with food products or raw materials. These MCTs can also beused as a glaze and polishing agent for confectionery products such as gummy- type candies. Solid MCT scan help to enhance aeration properties in bakery products.

★ MCT derivatives- structuredlipids

Medium chain triglycerides can be used to custom design fats. MCTs with conventional long chain fats give products with unique physical and nutritional products. MCT derivatives show unique properties compared to their corresponding physical blends. They may contribute nutritional and functional benefits to value added foods

Non-edible applications of coconut oil

One of the major non-edible applications of coconut oil is in the soap industries; one important chemical derivative of coconut oil is methyl esters of coconut fatty acids, which are produced by treating coconut oil with methyl alcohol. These methyl esters constitutes an important raw material  or the chemical industries as they are more stable and are easier to separate by fractional distillation.  Coconut oil has many other industrial uses in the pharmaceuticals, cosmetics, plastics, rubber  substitutes, synthetic resins etc. Coconut oil has also been found useful for mixing with diesel. These mixture in the proportion as 30:70 has given excellent road performance of diesel vehicles. Methyl esters of coconut oil fatty acids is also being used as lubricants and biodiesel in aviation industry
