Resumo: dc.description.abstractMost jellies are made from raw material obtained from mammals and the search for alternative sources is and environmental issue, because the generation of waste in the treatment of bovine leather is a big problem. The tilapia aquaculture has been highlighted, representing approximately 40% of the country’s production. The production of gelatin from tilapia skin shows a good alternative in the use of this waste, since it has a large amount of collagen in its composition. Gelatin is obtained from hydrolysis of collagen from an acidic or alkaline pretreatment. In this study four gentle methods were tested for the extraction of gelatin, three acid pretreatments and one neutral (water only) and features such as color, odor, chemical composition (moisture, ash, protein and lipid), yield and gel strength (Bloom) were evaluared. Gelatins obtained showed low moisture content, ash and lipids. About protein content, gelatins showed levels 77-81% and Bloom from medium to high (184-267g), and the gelatin extracted only in water showed high protein content and the second highest Bloom. Thus, we conclude that the extraction of gelatin from the skin of tilapia is a good alternative to gelatin from waste from mammals and a good option to use the large amount of waste generates in the production chain of fish because the gelatin obtained from this pretreatment showed characteristics similar to those obtained by more rigorous pre-treatments studied by other researchers.pt_BR
