A process for recovering oil entrained by the gums separated during an oilseed oil degumming process, comprising the stages of: a) making a countercurrent liquid/liquid solvent extraction of gums separated during degumming of oilseed oil; b) separating solvents from oil by in vacuo distillation in at least three steps; c) recovering the solvent from the extracted gums using a desolventizing equipment; d) adjusting the grain size of the dry gums (lecithins) thus obtained; and e) recovering the solvent from steps b) and c) in the system condensers and rectifying it in a standard rectifying column for reutilization in the process. Preferently, oilseeds or parts of oilseeds are selected from soybean, sunflower, and peanut. The solvent is selected from linear or branched C3-C6 ketones, linear or branched C3-C6 esters, linear or branched C3-C6 alcohols, linear or branched C3-C6 diols, and mixtures thereof. Preferently, the solvent is acetone. The invention also refers to dry particulate lecithins obtained by said process, useful as emulsifiers or dietary supplements, and to extraction meals comprising a substantially higher protein content as a result of not adding the product obtained from the process of the present invention.
