As an important vegetable oil, cottonseed oil has been used as cooking oil for a long time, especially in countries like the United States, China, Afghanistan, India and more. Cottonseed oil is extracted from seeds of cotton plant by different extracting methods. Similar to other oil-bearing seeds, cotton seed has outer shell and the kernel in the shell is the main part that contains cottonseed oil. The oil content of cotton seed kernel is about 35% ~ 45%, and protein is about 39% and 0.2%-2% of cotton phenol. However, the cotton phenol should be removed if the cotton seed oil is used as edible oil. And it is fairly easy to remove it through advance oil refinery technology. Since it is much cheaper than olive oil and canola oil, cottonseed oil is now widely used in the production of food, bread, snacks, margarine and other, not just used as the raw material for crisco shortening or potato chips.

Cottonseed Oil Extraction Process
The production of cottonseed oil involves a series of processing steps, including seeds treatment, oil pressing and oil refining.
- Cottonseed treatment
Any plant seeds should be cleaned thoroughly to remove impurities, this is the same to cotton seeds. Cotton seeds cleaning is done for high oil output and low oil loss. Cracking the kernel from cotton seed into adequate size is also important for cottonseed oil pressing. In order to ensure high oil output and enlarge the area of cotton seed embryo between the pressing screw, flaking is necessary. Then, cotton seed oil treatment comes to the last step cooking. Cooking is mainly to process best cotton seed flakes by controlling its the moisture through adjusting the cooking temperature.
- Cottonseed oil pressing
The core step to get cotton seed oil is oil pressing. Using our integrated cotton seed oil expeller can ensure higher quality and purer crude cottonseed oil. It is easy to operate, not have complicated operations. And it enables clean and sanitary cotton seed oil production.
