Partially defatted soyben meal a is achieved through mechanical extraction of oil. Usually only 12% of the oil is extracted, hence resulting to a final product with fat content at around 8% fat. Additionally the protein content is higher (40%) compared to full fat soya cake.
Soybean meal is the most important protein source used to feed farm animals. It represents two-thirds of the total world output of protein feedstuffs, including all other major oil meals and fish meal. Its feeding value is unsurpassed by any other plant protein source and it is the standard to which other protein sources are compared.
Other types of soybean meal include the hulls or part of the hulls and contain less than 47% protein and more than 6% crude fibre. In solvent-extracted soybean meals, the oil content is typically lower than 2% while it exceeds 3% in mechanically-extracted meals
