Abstract[EN] This paper is a report on the use of NaOH to skin different species of fish. The purpose is to save handwork in the peeling factories. Experiences have been made with the species: frozen Merluccius capensis, Trachurus trachurus, Scomber scombrus and Sardina pilchardus, both on whole specimens and on headed and eviscerated ones. In every case the best conditions are specified to skin the different species. A more detailed description of the experiments carried on is presented in the tables and figures and precise the conditions to obtain an optimum product. After treatment with NaOH, the fish is washed in water and neutralized with citric acid. It could be seen that it is easier to skin the frozen fish, by its rigidness and hardness, than the fresh one
[ES] 1. Se ha logrado el pelado químico con baño de NaOH al 2% de la merluza congelada y descongelada y la caballa, jurel y sardina congelados. 2. La neutralización de los restos de NaOH se hace (después de un lavado con agua corriente), con una disolución de ácido cítrico al 2%. 3. Se especifican en cada caso las condiciones óptimas para obtener: a) Un pescado que salga del baño de NaOH con piel y se desprenda ésta posteriormente frotando suavemente, o con lavado en chorro de agua.
