A countercurrent extraction process that involves a plurality of mixing and separation steps for the fractionation of a food material containing phospholipids in two or more fractions enriched in one or more phospholipids, comprising the following steps: i) contacting the starting material containing phospholipids under stirring with an extractant comprising an aliphatic alcohol selected from C1 to C3 alcohols and mixtures thereof for a period of time sufficient to effect the transfer of at least a fraction of the phospholipids to the extractant； ii) separating the mixture obtained in an extract enriched in phospholipids from the residual refining by a process comprising applying centrifugal forces； wherein the phospholipid-enriched extract of each separation stage is at least partly returned to the previous one, or to a subsequent additional mixing stage, where the general process flow is countercurrent which means that the phospholipid-containing material is contacts the extractant of a second or subsequent stage in a first stage, and so on and where a phospholipid enriched final extract is separated from the first residual refining； wherein the final extract comprises at least 25% by weight phosphatidylcholine (PC), and more than 50% by weight insoluble in acetone (AI).Un proceso de extracción a contracorriente que implica una pluralidad de etapas de mezclado y separación para el fraccionamiento de un material alimenticio que contiene fosfolípidos en dos o más fracciones enriquecidas en uno o más fosfolípidos, que comprende las siguientes etapas: i) poner en contacto el material de partida que contiene fosfolípidos bajo agitación con un extractante que comprende un alcohol alifático seleccionado de alcoholes de C1 a C3 y mezclas de los mismos durante un periodo de tiempo suficiente para efectuar la transferencia de al menos una fracción de los fosfolípidos al extractante； ii) separar la mezcla obtenida en un extracto enriquecido en fosfolípidos a partir del refin
