This relates to a method for providing a basis of soybean (511) from soybean Seeds (1), comprising the following steps: a) providing an aqueous Paste comprising soybeans Crushed (3) (4)； (b) separating the Pulp (3) provided in point (6) into a First fraction rich in insoluble parts of the soybean and a Second fraction L (5) u00edquida poor insoluble parts of soybeansThrough the use of a suitable means of Separation； (c) adjust the Water content (7) of the first portion (6) for providing between 1% and 20% by weight of total Solids (8)； (d) to submit the first fraction (8), between 1% and 20% by weight Total Solids to an ultrasound Treatment (9) Where the treatment of Ultrasound is applied at a frequency of 16 kHz and 100 kHz.Energy input with an average of at least 5 J per milliliter of said first portion (8) (10)； (e) separating the first fraction (8) treated with Ultrasound in a Third portion (12) rich in insoluble parts of soybean SEED, and the Fourth Liquid fraction (11) in poor parts insolub Les of soybeansThrough the use of a suitable means of Separation； where the basis of soybean is provided as the second Liquid fraction (5) and the Fourth Liquid fraction (11).It has been discovered that the procedure results in an efficient process for providing soy extract and one or more water-soluble compounds and / or water dispersible from seeds of soy, such as Proteins, carbohydrates, such as Sugars, Oligosaccharides and Alim Fibers Entarias), soluble Oils, Vitamins, Minerals, carotenoids, and isoflavones.La presente se refiere a un procedimiento para proveer una base de soja (5, 11) a partir de semillas de soja (1) que comprende los siguientes pasos: a) proveer una pasta acuosa que comprenda semillas de soja trituradas (3)； b) separar (4) la pasta (3) provista en el punto a en una primera fracción (6) rica en partes insolubles de semilla de soja y una segunda fracción líquida (5) pobre en partes insolubles de semilla de soja, a través del uso de un medio de separac
