| dc.description | Transesterification of edible oils and fats is an option for producing commercial fats free of trans fatty acids, which may result in improved physical and nutritional properties of raw materials or interme- diate products of oil palm processing. Transesterification consists of the redistribution of fatty acids within triacylglycerides that takes place inside the molecule itself or in different molecules. The process is carried out by lipolytic enzymes which act as biologic catalysts that hydrolise the triacylglycerol ester bond in the water/oil interface, releasing fatty acids, glycerol, monoacylglycerol and diacylglycerol. They also act as catalysts of water-insoluble esters through interesterification, alcoholysis and acidolysis reactions. Lipolytic enzymes are a “clean technolog” which may be an alternative to partial hydrogenation, the process used to transform oils into solid or semi-solid fats through hydrogen addition, the result of which are oils or fats with high concentration of trans fatty acids that may be harmful to human health mainly because of the their potential to elevate LDL and triglyceride levels. Finally, the palm oil sector is working on the development of lipolytic enzymes, which appear to be highly promising as a technology for enhancing oils and fats in a sector that is increasingly demanding in terms of quality and nutritional benefits.

| dc.description | La transesterificación de aceites y grasas comestibles es una alternativa de producción de grasas comerciales libres de ácidos grasos tipo trans, que puede repercutir en la mejora de las propiedades físicas y nutricionales de materias primas o productos intermediarios del procesamiento del aceite de palma. Es una redistribución de ácidos grasos entre los triacilglicéridos, que tiene lugar dentro de la misma molécula o en diferentes. Este proceso lo llevan a cabo las enzimas lipolíticas, catalizadores biológicos que hidrolizan el enlace éster del triacilglicerol en la interfase agua/aceite, liberando áci- dos grasos, glicerol, monoacilglicerol y diacilglicerol. También catalizan ésteres insolubles en agua a través de reacciones de interesterificación, alcohólisis y acidólisis. El uso de las enzimas lipolíticas es una “tecnología limpia”, que puede ser alterna al proceso de hidrogenación parcial empleado para que los aceites se transformen en grasas semisólidas o sólidas, mediante la adición de hidrógeno, dejando como resultado aceites o grasas con altas concentraciones de ácidos grasos tipo trans, nocivos para la salud, principalmente porque pueden elevar el colesterol LDL y los triglicéridos. Esta tecnología, que en el sector del aceite de palma está en desarrollo, muestra alto potencial de mejoramiento de los aceites y las grasas en un mercado cada vez más exigente en calidad y beneficios nutricionales. | es-ES |
