Irreplaceable animal feed is the extracted soybean meal. In its production, about 18-20% of soybean oil is extracted from crushed soybeans by solvents (hexane-based compound). After this, most of the used solvent is removed but leaving trace amounts. It must not exceeding the maximum allowed limit (under the Directive 2009/32/EU, up to 30 mg/kg). This resulting soybean meal contains high amounts of proteins (44-48%) and low amounts of oil (1-2%). This is the most widely used raw material in the feed industry.

Heat treated soybean seed “full fat” soya has a high protein content (33-35%), a favorable content of essential amino acids and high energy value (18-22 % of oil). The oil content in some feed formula limits the maximum rate in the recipes.

Due to the high content of anti-nutrients, soybeans need to be heat treated. There are many ways to remove heat sensitive anti-nutrients (Trypsine Inhibitor and Lectin), however, removal of other anti-nutrients, such as Glycinin and Beta-Conglycinin, are possible only by extrusion, which is costly.
