Prior to World War II, Cottonseed products dominated both the protein and vegetable oil markets. Conservation replaced development and promotion during the war. After the war, mill capacity icnreased and solvent extraction replaced hydraulic and expeller methods. However, problems with dust increased with capacity, making worker safety more of an issue. During the 1950s, mills began processing three cuts of lint instead of just two. Gossypol toxicity was recognized as an important problem. During the 1960s, the industry introduced micella refining of crude cottonseed oil Aflatoxin was recognized as an important problem. During the 1970s, researchers developed the ammoniation process to detoxify aflatoxin, which by then had become a major problem. The energy crisis drove research and development into energy efficient processes. During the 1980s, the major events were OSHA regulations on cotton dust exposure, feeding whole cottonseed to dairy cattle, and the loss of about half the mills operating in 1980 by 1990.
