For quite some time oil meals have been used as animal feed. With regards to food sustainability, FST has also looked at these press cakes to bring these nutritious foods back into the human food chain.
Most oil press cakes contain lots of protein and fibres and are therefore interesting from a nutrition point of view. In addition, oil meals still do contain some oil. Depending on which oil seed has been used these oils consist of valuable poly-unsaturated fatty acids.
As most oilseeds contain less than 50% oil one can only imagine the enormous amounts of press cakes that must be around judging by the quantities of edible oils that are being consumed.
