Technical Abstract: In addition to fiber, the cotton plant produces seed that is used for animal feeding and for the recovery of oil. “Gin run” whole cottonseed is widely used as a protein supplement for feeding ruminant animals and is of special value to the dairy industry because it increases the butterfat content of milk. The oil is used almost exclusively for food formulation and processing. It is prized as frying oil for the toasted or nutty aroma it imparts to snack foods. It is also widely used in the formulation of solid-fat products, because it forms small crystallites that provide these products with a smooth consistency, fluid plasticity, and a preferred “mouth feel.” In addition to oil, extraction of cottonseed also produces meal, hulls, and linters as co-products. The meal is used primarily as a protein source for ruminant animal feeds. Hulls are used as source of roughage for cattle and as a substrate for mushroom production. Linters are used for battings, felt liners and insulation, but also as a source of chemical cellulose.
