Abstract
The major oilseed crops were domesticated primarily as sources of edible oil. However, in all cases, yields of by-products are greater than the oil fraction, and, in reality, all oilseed crops serve dual purposes as sources of oil and of protein for human food, animal feed, and industrial products. Each crop has special requirements for extraction and for processing of oil and meal, and each has limitations as to location and timing of production and as to processibility in oil mills originally designed for other crops. Further, each oilseed has unique cultural, economic and utilization characteristics; for example, rapeseed (Brassica) can be grown in cool climates with short growing seasons. Cottonseed (Gossypium) is a by-product of the more valuable fiber crop, and its availability is dictated by the profitability of growing cotton for the world market. Although peanuts (Arachis hypogaea) are used primarily as peanut butter and nuts in the United States, they are almost exclusively pressed for oil in other countries. In this paper, cultural practices and processing requirements of soybean (Glycine max), cottonseed, sunflower (Helianthus annuus), rapeseed, peanut, and sesame (Sesamum indicum) oils and byproducts are compared, as well as compositions of major oilmilling fractions, oils and proteins.
