Caracterización de un hidrolizado proteico enzimático obtenido del pez caribe colorado (pygocentrus cariba humboldt, 1821)

the goal of this work was to obtain protein hydrolysates by means of enzymatic reaction from colored ？caribe？ fish (pygocentrus cariba humboldt, 1821). a sample of 50kg of adult specimens, from the igües river (el baúl, cojedes, venezuela) was selected. every specimen was cut manually with a knife; the muscular tissue without skin was ground in an electric grinder, packed in polyethylene bags and stored at -18oc. hydrolysis was catalyzed by means of a food grade commercial protease (alcalase？ 2.4l). the maximum hydrolysis degree (hd) obtained was 10.5%. the yield in dried protein hydrolysate (dph) increased with hd and its maximum value was 13.7g dph/100g of moist grounded muscle. proximate analysis and functional properties of hydrolysates showed significant differences (p<0.05). protein hydrolysis of the colored caribe fish with alcalase？ is a commendable alternative to profit from this underutilized species.
