“…The data described here are a continuation of this study, designed to explore the chemical inactivation of the residual cyclopropenoid fatty acids, ]n situ, in cottonseed meals. As in the first study, commercially available screw-pressed and direct solvent extracted cottonseed meals were employed and techniques considered which might be adaptable as an adjunct to presently employed commercial processing methods (5). However, the latter condition was not the sole criterion on which the various treatments were based.…”

Chemical inactivation of cyclopropenoid fatty acids in commercial cottonseed meals was explored with three classes of compounds : anhydrous gases, organic acids and sulfhydryl compounds. Of the reagents screened, sulfur dioxide reduced the cyclopropenoid content by over 90% while free cottonseed fatty acids and thioglycollic acid reduced the cyclopropenoid fatty acid content by over 30%. Large batches of the above three selected meals, as well as a control commercial screw-pressed meal, were then incorporated at 20 wt % levels in the rations of laying hens. A negative control containing 25% soybean meal and a positive control containing a 2% refined cottonseed oil of known CPA content were also employed. During a four-week feeding period, eggs were collected during the third and fourth week and stored at 35 F for periods of 3 and 6 months. Overall egg quality and the fatty acid distribution of the yolk lipids were determined after the 3 and 6 months' storage periods.

“…This study was directed toward the removal of the cyclopropenoid fatty acid moieties in commercially available cottonseed meals by solvent-extraction procedures which may be adaptable as an adjunct to presently employed commercial processing methods (2). Several solvent-extraction procedures have been reported to be useful for the removal of cyclopropenoid fatty acids from decorticated cottonseed flakes (3)(4)(5) as well as preserving the nutrient properties of the resulting meal (6).…”

A summary of many methods for removing fats and oils from a variety of oilseeds and fatty materials, starting with some early methods and arriving at modern state‐of‐the‐art methods. The summary covers preparation, including cracking, flaking, cooking and drying, and extrusion preparation. Hydraulic crushing is covered and screw pressing, both prepressing and fullpressing. Many early and modern screw presses of different manufacture are described. Batch rendering systems for animal fats are described as well as the more efficient continuous systems for dry rendering and systems for slurry rendering using multiple effect evaporators. Digestive rendering is also discussed. Solvent extraction is described, starting with theories behind solvent extraction, various solvents used, early equipment, and state‐of‐the‐art modern extractors. Also discussed are solvent recovery from miscella, marc, and the air and water effluents from the extraction system. The chapter ends with methods for obtaining oil from olives and from palm fruit.
