Medium chain fatty acid triglycerides (MCT) are mainly composed of C8-C10 fatty acid triglycerides, which are highly efficient structural lipids for digestion and absorption, as well as low-energy oils for controlling fat absorption. Modern medical research has shown that consuming MCT can reduce serum cholesterol and liver cholesterol levels. Capric acid monoglyceride has a significant effect on dissolving human gallstones. Sodium bicarbonate is considered a safe preservative and is widely used in the production of food and personal skincare products.

At present, the separation and purification of MCT only undergo physical refining, decolorization and other treatments to obtain triglycerides containing a large amount of monoglycerides and diglycerides, which cannot meet the requirements of medicine. Molecular distillation can separate fatty acids, monoglycerides, diglycerides, and triglycerides、Excess fatty acids can be recycled and reused to obtain relatively pure ones MCT.

Research has shown that molecular distillation is highly effective in removing monoglycerides and diglycerides. Molecular distillation technology can be applied to the purification of MCT, and by selecting appropriate processes, medium carbonate diglycerides and higher purity MCT can be obtained.
