Cotton-seed Oil 

 Cotton-seed oil is expressed from the ripe seeds of various 

 species of Gossypium {Malvaceae — Mallow Family), na- 

 tive of tropical regions and extensively cultivated. The 

 seeds yield about 1/5 of their weight of oil. After the 

 cotton has been removed as completely as practicable the 

 seeds are crushed and the hulls removed. The kernels 

 are then partly cooked, after which the oil is removed by 

 pressure. The cake that remains is ground into cotton- 

 seed meal, which is largely used as a cattle food. The 

 finer grades of cotton oil are used as food, especially in 

 cooking. A butter substitute is made from it. The 

 poorer qualities are used for lubrication and soap-making 

 and for other purposes.
