During the refining of vegetable oils, it is aimed to eliminate or reduce the number of unwanted substances in the oils. During the refining process, many bioactive components present in the structure of vegetable oils can be mixed with deodorization distillate in the final stage of refining and be lost in waste. These substances may vary according to the type of vegetable oils, but generally, tocopherols, tocotrienols, sterols, squalene, and different fatty acids are exemplified. In general, these substances are called “bioactive substances” because of their bioavailability and many of them can be used as a raw material in different sectors. For example, squalene, which exists in high amounts in olive oil and pomace oil and is a by-product of olive oil production is used in the cosmetic industry. Tocopherols and tocotrienols, which are present in significant amounts in sunflower oil, hazelnut oil, olive oil, and palm oil, have antioxidant properties and are bioactive components that are emphasized by both the food industry and all consumers seeking healthy food. The oleic and palmitic fatty acids in these oils are important components of the chemical industry. 'Molecular Distillation Technology' is an important solution for separating and enriching these components from deodorization distillate. The principle of molecular distillation is one of the components of the liquid flowing as a film separates into two phases according to the free path of each component. When it exposed to the cold surface, concentrates and accumulates. This study explains the advances in the separation of bioactive substances from the deodorization distillate. The principle of molecular distillation is the evaporation of the components in the liquid flowing as a film over a hot surface in a cell containing two mutually heated and cooled surfaces, since the shorter the average free path, the higher the molecular weight, and the lower the free path of the low molecular weight components. It will contact the cold surface and concentrate here to collect. This study explains the advances in the separation of bioactive substances from the deodorization distillate of molecular distillation technology and discusses the potential widespread effects in the future.
