[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 canning factories. Experiences have been made with the species Scombrus scombrus, Trachurus trachurus and Sardina pilchardus, both on whole specimens and on headed and eviscerated ones. In general, a 2% NaOH solution at 60-80ºC acting during 2 minutes gives fair results. 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. A testing panel found practically no difference between hand skinned canned fish, and fish canned after being skinned with NaOH
