Sesame oil can be divided into two categories according to its aroma characteristics:

The special components in sesame are processed by the high-temperature stir-frying process to produce special fragrant substances, which makes sesame oil have unique fragrance, different from other edible vegetable oils, so it is called fragrant oil.

- Sesame oil sold in the market mainly comes from small individual workshops, which have no scale of production, lack of quality control means, and labels often change.
- Many vegetable markets and fairs have stalls for processing sesame oil on the spot, but the water substitution method can not be made in the market because of the technological requirements, while the crushing method is to use other edible oils to soak sesame seeds before extracting them. Sesame crude oil accounts for about one-half of the total.
- part of the store is to use the essence of food blending other edible oil shoddy, to seek high profit.
Adulteration of sesame oil has always existed. Vegetable oil, and lack of quantitative basis. The range of fatty acid composition of sesame oil is stipulated in CODEXSTAN 26-1981, which provides a feasible basis for identifying adulteration of sesame oil.

Oil extraction by water substitution
It is easy to separate oil embryos with high-quality drinking water. No chemical solvent is needed in the process of oil extraction, so there is no residual chemical solvent.
