the present invention describes a process for obtaining gelatin g\u00e9lifiantes enzyme of marine origin. the present invention provides more new gelatin from the skin of the common cuttlefish (sepia officinalis).the method according to the invention is distinguished from known processes in that the step of dissolving the collagen is provided by an enzymatic treatment with pepsin, an alternative method in the process of acid.a second advantage of the method lies in the use of the skin of cuttlefish, produced no value from the processing and packaging of the products, as a raw material for the extraction of gelatin.according to the method of the invention, the production of gelatin is mainly based on three steps: (i) alkali pretreatment to remove non collagenous proteins, (ii) a commercial enzymatic treatment with pepsin for softening skin preparation the distortion and the extraction.(iii) finally, the extraction of gelatin during 4 to 4 degrees c under agitation to 200 rpm. in the context of this patent, increasing concentrations in pepsin have been applied in the extraction of gelatin. according to the method of the invention, the enzyme treatment significantly improves the performance of the gelatine.the method of the invention is used to obtain high quality gelatin cuttlefish g\u00e9lifiantes without taste or smell of fish. well, it has been demonstrated that the enzyme treatment with different doses of enzymes, which led to the award of gelatins with different properties.the physicochemical properties and textural and techno functional gelatin prepared have been studied. most of the values determined level bloom, melting temperatures and transition, gelation, etc.) decreased with the dose of enzyme was used.the comparative study of the functional properties of gelatin showed that with the increase of the concentration of pepsin, soap and the reduced capacity, foam stability, emulsifying properties and that are comparable.the gelatin obtained at a concentration
