    In this study, the following commercial enzymes were evaluated in the enzymatic extraction of oil and protein from coconut: Celluclast, Termamyl, Viscozyme, Neutrase y Protease. Preliminary experiments were carried out for selection of enzymes, enzyme concentration and incubation time. In order to verify the effects of pH and water/substrate ratio, a response surface methodology was applied based in a 32 full factorial experimental design. The pH is the most meaningful parameter on oil and protein extraction yields, with a significance level higher than 90%. The maximal extraction yields of oil and protein emulsion (83%) was reached using Viscozyme L and subsequently Neutrase 1.5 MG at concentrations of 0.6% (w/w) and 0.3% (w/w), respectively, total incubation time of 60 minutes, substrate/water ratio 1:6 and pH around 7 (no adjustment).En este trabajo diferentes enzimas hidroliticos fueron usados para la extracci贸n de aceite y prote铆na de coco: Celluclast, Termamyl, Viscozyme, Neutrase y Protease producidos por Novo Nordisk. Experimientos preliminares fueron encaminados a la selecci贸n de los extractos enzimaticos, de las concentraciones de las enzimas y de los tiempos de incubaci贸n. La t茅cnica de an谩lisis de varianza, mediante un delineamiento factorial en tres niveles, fue usada para la optimizaci贸n de los procesos con relaci贸n a los par谩metros pH y raz贸n sustrato/agua. Comparando con la extracci贸n acuosa todos los enzimas hidroliticos incrementan la extracci贸n de aceite y prote铆na vegetal de coco. Los coeficientes de correlaci贸n muestran que el pH fu茅 el par谩metro mas significativo (p< 0,10). Las condiciones 贸ptimas para la extracci贸n de aceite y prote铆na fueron: concentraci贸n de las enzimas Viscozyme y Neutrase 0.6 % (w/w) y 0.3 % (w/w), respectivamente, tiempo de incubaci贸n 30 minutos, raz贸n sustrato/agua 1:6 y pH 7
