Oilcakes are a byproduct of oil extraction, which is the extraction of oil from seeds or nuts. The remaining solid matter is referred to as oilcake or meal. It is a high-protein source that is used as animal feed or as a fertilizer. Oilcakes, which are both edible and non-edible, are used as manure.
Mustard cakes, Neem Cakes, and Groundnut Cakes are excellent examples of oil cakes. Certain oil cakes made from poisonous seeds such as castor beans and tung nuts are used as fertilizers instead of animal feed.
