Medium‐chain triglycerides (MCT) that contain caprylic acid (C 8:0 ) and capric acid (C 10:0 ) have immense medicinal and nutritional importance. Coconut oil can be used as a starting raw material for the production of MCT. The process, based on the interchange reaction between triglycerides and methyl esters of medium‐chain fatty acids by chemical catalyst (sodium methoxide) or lipase (Mucor miehei) catalyst, appears to be technically feasible. Coconut oils with 25–28.3% (w/w) and 22.1–25% (w/w) medium‐chain fatty acids have been obtained by chemical and lipase‐catalyzed interchange reactions. Coconut olein has also been modified with C 8:0 and C 10:0 fatty acids, individually as well as with their mixtures, by chemical and lipase‐catalyzed interchange reactions. Coconut olein is a better raw material than coconut oil for production of mediumchain fatty acid‐rich triglyceride products by both chemical and lipase‐catalyzed processes.
