Abstract
En un aspecto, la presente invención se refiere a un proceso para producir colesterol a partir de aceite de pescado, que comprende de manera general los pasos de transesterificar el aceite refinado utilizando un catalizador básico. Obtener una corriente concentrada en colesterol y otra en acido grasos Omega-3 EPA y DHA a través de destilación molecular. Saponificar la corriente rica en colesterol utilizando bases como hidróxido de potasio, hidróxido de potasio, hidróxido de sodio o cloruro de calcio. La mezcla posteriormente se saponifica con el tiempo y temperatura con agitación y reflujo constante. Se realizan varias extracción con solventes como tolueno, dicloruro de etileno, cloruro de metileno, éter di etílico, éter de petróleo, acetona, benceno o un hexano y centrifugaciones para obtener la materia insaponificable. Esta última corriente es cristalizada utilizando acetona, benceno, tolueno, éter di etílico, éter de petróleo o hexano para obtención de colesterol con pureza mínima de 95%. Además, se convierte el jabón obtenido de la saponificación a forma de etil éster aplicando reacciones de desdoblado y esterilización acida.In one aspect, the present invention relates to a process for producing cholesterol from fish oil, generally comprising the steps of transesterifying the refined oil using a basic catalyst. Obtain a stream concentrated in cholesterol and another in Omega-3 EPA and DHA fatty acids through molecular distillation. Saponify the cholesterol-rich stream using bases such as potassium hydroxide, potassium hydroxide, sodium hydroxide, or calcium chloride. The mixture is subsequently saponified with time and temperature with constant stirring and reflux. Several extractions with solvents such as toluene, ethylene dichloride, methylene chloride, diethyl ether, petroleum ether, acetone, benzene or hexane and centrifugations are carried out to obtain the unsaponifiable matter. This last current is crystallized using acetone, benzene, toluene, diethyl ether, petroleum ether or hexane to obtain cholesterol with a minimum purity of 95%. In addition, the soap obtained from saponification is converted to the form of ethyl ester by applying splitting reactions and acid sterilization.
