Oct 22, 2021 Molecular distillation technology is widely used in the food industry, mainly for the separation of mixed oils. W (monoglycerides of fatty acids) can be obtained; 90% high-purity products. After evaporating the monoglyceride molecules from the surface of the distillate, they are immediately cooled to achieve separation. ...
