1, the output of cottonseed oil is low, so the supply is relatively small.

2, cottonseed oil is not suitable for eating, and now it is only used in industry.

Cottonseed oil is the oil squeezed from cotton seeds, which can be divided into pressed cottonseed oil, leached cottonseed oil, transgenic cottonseed oil, cottonseed crude oil and finished cottonseed oil. It is darker in color than other oils, and can be eaten by people after refining. It contains a lot of fatty acids necessary for human body, and it is most suitable to be mixed with animal fat.
