Sesame oil is known as a "scavenger of blood vessels," beneficial for moisturizing skin, reducing blemishes, and improving eyesight. It is most effective in affecting the central nervous system, thus delaying the onset of disease. Furthermore, it has a good preventative effect on some diseases. Therefore, sesame oil is very popular worldwide. So how is sesame oil produced?
First, the sesame seeds undergo pre-treatment. They are poured into a sesame dryer and dehydrator to remove impurities adhering to the surface, ensuring the purity of the raw material. This is a crucial step in ensuring oil quality and equipment safety. Next, the washed sesame seeds are stir-fried in a roaster . This step is key to the formation of sesame oil's aroma. Precise control of temperature and time allows the sesame seeds to develop a unique and rich aroma. Temperature control is extremely important; too low a temperature will result in insufficient aroma, while too high a temperature will burn the sesame seeds, making the final oil taste bitter. The steamed and stir-fried sesame seeds are then poured into a screw press, where physical pressure is used to extract the oil from within the sesame seeds. The crude oil produced is then poured into a plate and frame filter. This step is to remove large particles of cake residue from the crude oil. If higher requirements are needed for the sesame oil, such as a light color and high smoke point, it can be further refined using equipment to undergo processes such as dehydration, deacidification, deodorization, and decolorization.
