Abstract

La presente describe un proceso para la obtención de aceite vegetal rico en 1,3-diacilgliceroles con al menos 10% en peso de 1,3-diacilgliceroles mediante una reacción de transesterificación de triacilgliceroles y glicerina en presencia de un catalizador sólido. Además, la presente describe un aceite vegetal rico en 1,3-diacilgliceroles con un contenido entre 20 y 40% en peso de 1,3-diacilgliceroles. Reivindicación 1: Un proceso de obtención de aceite vegetal rico en 1,3-diacilgliceroles con al menos 10% en peso de 1,3-diacilgliceroles caracterizado porque comprende los siguientes pasos: a) mezclar aceite vegetal con glicerina en una proporción molar con glicerina/aceite de entre 0,5 y 2; b) hacer reaccionar, durante un tiempo de entre 4 y 8 horas, la mezcla del paso a), a una, temperatura de entre 180 y 240ºC en atmósfera inerte, en presencia de catalizador sólido de MgO en una proporción de entre 0,1% y 3% en peso respecto de la masa de aceite; c) enfriar por un tiempo de entre 2 y 14 horas en agitación constante; d) filtrar el medio para la eliminación del catalizador; e) separar la glicerina remanente para obtener el aceite vegetal rico en 1,3-diacilgliceroles con al menos 10% en peso de 1,3-diacilgliceroles en la fase oleosa.The present describes a process for obtaining vegetable oil rich in 1,3-diacylglycerols with at least 10% by weight of 1,3-diacylglycerols by a transesterification reaction of triacylglycerols and glycerin in the presence of a solid catalyst. In addition, the present discloses a vegetable oil rich in 1,3-diacylglycerols with a content between 20 and 40% by weight of 1,3-diacylglycerols. Claim 1: A process for obtaining vegetable oil rich in 1,3-diacylglycerols with at least 10% by weight of 1,3-diacylglycerols characterized in that it comprises the following steps: a) mixing vegetable oil with glycerin in a molar ratio with glycerin / oil between 0.5 and 2; b) react, for a time between 4 and 8 hours, the mixture of step a), at a temperature between 180 and 240 ° C in an inert atmosphere, in the presence of a solid MgO catalyst in a proportion of between 0.1 % and 3% by weight with respect to the oil mass; c) cool for a time between 2 and 14 hours under constant stirring; d) filter the means for catalyst removal; e) separating the remaining glycerin to obtain the vegetable oil rich in 1,3-diacylglycerols with at least 10% by weight of 1,3-diacylglycerols in the oil phase.
