What is the processing technology of sesame oil?

Sesame oil has two processing technologies, namely:

1, oil extraction by water substitution. This process is to separate oil from water by using the different affinity of non-oil components in oil to oil and water and the different specific gravity of oil and water. The process is as follows: stir-fry the screened sesame seeds in a pot, then grind them into fine sesame paste blanks with a stone mill, then put the oil blanks and boiling water into the pot in proportion, replace the oil by stirring and settling, and separate the residual oil from sesame residue through long-term vibration and rolling with a heavy copper hammer.

2. Squeeze oil. This method uses physical machinery to separate oil directly through physical pressure, and there is no chemical additive in the whole process, which ensures the safety, hygiene and pollution-free products and the natural nutrition is not destroyed.
