Abstract
Method for producing edible soybean meal which is essentially free from bitter taste by moistening pieces, e.g., small flakes, of soybeans to increase their water content to 12 to 25%, heat treating the moistened pieces at 90.degree.-120.degree. C. while subjecting them to a slow, compacting mechanical movement sufficient to achieve a minimum bulk weight of at least about 400 kg/m.sup.3, thereafter extracting soybean oil from the pieces with a non-polar solvent, and drying the soybean pieces to obtain soybean meal which is essentially without bitter taste.
Claims10
A method for producing edible soybean meal substantially free from bitter taste which comprises moistening oil-containing pieces of soybeans in the form of crushed and rolled flakes to raise the water content thereof to 12-25% by weight and heat treating the moistened flakes at temperatures in the range of 90 to 120.degree. C. for about 10 to 90 minutes while subjecting the flakes to a mechanical compacting movement sufficient to attain a minimum bulk weight of said flakes of at least about 400 kg/m.sup.3, thereafter extracting soybean oil from the heat treated flakes having said minimum bulk weight with a non-polar solvent, separating the soybean flakes after extraction of the oil therefrom from the bulk of the extracting solvent, and drying the separated solvent-wetted soybean flakes by vaporizing the residual solvent therefrom to obtain a soybean meal substantially free from bitter taste.
