Rapeseed oil production occupies third place in the world production of vegetable and marine oils. It ranks fifth in production of oilseed proteins. Rapeseed is one of the major oilseed crops in the Far East and in Northern Europe and North America. Rapeseed is mainly used for oil production; also by-products of oil extraction are used in animal feed. The oil content of the seed ranges from 33.2 to 47.6% (8.5% moisture basis) and yields 29.5 to 57.5% protein (oil-free/defatted meal, 8.5% moisture basis).
