Cottonseed Oil an overview ScienceDirect Topics
A.J. Dijkstra, in Encyclopedia of Food and Health, 2016 Cottonseed oil (Gossypium hirsutum)Cottonseed oil is a by-product of the cotton industry and its production forms the cradle of the modern oil refining processes and many of its analyses. Cottonseed oil is exceptional in that its alkali refining process is carried out on the miscella. The miscella resulting from the solvent extraction is
Cottonseeds are rich in oil and proteins and are therefore used for cottonseed oil production and as a feed supplement for cattle and sheep. According to the Food and Agriculture Organization of the United Nations, cottonseed oil is a type of vegetable oil used mainly as food.

Oil Refining: Since the crude cottonseed oil contains high content of gossypol, it needed to be refined to improve the quality and ensure the final refined cottonseed oil is completely safe for eating. The general refining process in cottonseed oil mills is degumming, deacification, decolorizing, deordorizing, and

Human body consumption of cottonseed oil is up to 98%. Cottonseed Oil Needs Refining. It is said that refining process can reduce toxicity. Cottonseed oil is one of main cooking oil. But crude cottonseed oil contains gossypol (approximate 1%), colloid and waxiness (content vary with shell content), and the quality is poor.
9.11.1 Vegetable Oil Processing 9.11.1.1 General1-5 The industry group producing fats and oils includes cottonseed oil mills, soybean oil mills, vegetable oil mills (other than corn germ, cottonseed, and soybean), and other mills. Wet corn germ mills are the primary producers of corn germ oil. Approximately 137 vegetable oil plants operate in the United States.
Chapter 5 : Processing and refining edible oils
For refined oils such as sunflowerseed, cottonseed and rapeseed oil, an upper limit of 3035 percent loss of tocopherols throughout the entire processing would still satisfy the generally accepted criterion of oc-tocopherol equivalents/linoleic acid ³ 0.6 mg/g (eager, 1975).
This industry profile of the vegetable oil industry provides information to be used to support the EIA of the NESHAP. The vegetable oil industry includes the following SIC codes: SIC 2046—Wet corn germ Milling, SIC 2075—Soybean Oil Mills, SIC 2074—Cottonseed Oil Mills, and SIC 2076—Vegetable Oil Mills, not elsewhere classified (N.E.C.).
Basics of Alkali Refining of Vegetable Oils
Alkali Refining: Plant Design Acid Conditioning The acid is circulated with a certain pressure by a circulating pump. The dosing is done by a magnetic flowmeter and a pneumatic dosing valve. The acid flow is controlled by the PLC in relation to the oil flow. Acid and oil is mixed intensively by a dynamic mixer followed by a retention time (5min.)
Oil Refining: Since the crude cottonseed oil contains high content of gossypol, it needed to be refined to improve the quality and ensure the final refined cottonseed oil is completely safe for eating. The general refining process in cottonseed oil mills is degumming, deacification, decolorizing, deordorizing, and fractionation.
