Abstract

BELEN CAMACHO, Douglas R et al. Characterization of a protein enzymatic hydrolysate obtained from the colored ‘caribe’ fish (pygocentrus cariba humboldt, 1821). INCI [online]. 2007, vol.32, n.3, pp.188-194. ISSN 0378-1844.

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.
