| Summary: | Esse experimento foi elaborado em parceria com o CENAQUA (Centro Nacional de Quelônios do Amazonas) e a Pró-Fauna (localizada em Iguape - SP) objetivando o estudo da validade comercial e a aceitabilidade da carne de tartaruga-da-amazônia criada em cativeiro. Foi avaliado o efeito do tempo de estocagem de amostras de carne de 14 tartarugas (7 fêmeas e 7 machos) nos dias 01, 30, 60 e 120, estocadas a -10 ºC, nos valores de pH e de Bases Voláteis Totais (BVT), cor, textura, odor e prova de cocção. Observou-se diferença significativa entre os valores de pH em relação ao tempo de estocagem nos dias 01 (5,81 e 5,81), 30 (6,04 e 6,05), 60 (6,22 e 6,23) e 120 (6,30 e 6,30), respectivamente para a carne das fêmeas e machos. Entre os sexos não houve diferença significativa. Quanto a BVT o tempo de estocagem influenciou significativamente entre os dias 01 (11,34 e 11,74 g/100g), 30 (13,92 e 13,90 g/100g) e 120 (17,62 e 17,82 g/100g); entre os dias 30 (13,92 e 13,90 g/100g) e 60 (14,02 e 14,06 g/100g) não observou-se diferença significativa, respectivamente para a carne de fêmeas e machos. Entre os sexos não ocorreu diferenças significativas. A cor, textura, odor e a prova de cocção não apresentaram alteração ao longo do tempo de estocagem. A carne de tartaruga obteve media de aceitabilidade global de 7,04. De acordo com os resultados obtidos concluímos que, pelas provas de pH e BVT, a carne de tartaruga pode ter uma validade comercial de 120 dias, quando embaladas a vácuo e estocadas a -10 ºC, e que a os provadores gostaram muito desse tipo de carne.<br>This research was developed in partnership with CENAQUA and Pró-Fauna with the objective of studying commercial validity and acceptance of the meat of Amazon-turtle that was bred in captivity. The effect of the storage period was evaluated on meat samples of fourteen turtles (7 female and 7 male ) stored in a period of 1, 30, 60, and 120 days at a temperature of -100Celsius, concerning to values of pH, total volatile bases, color, scent, and cooking test. Significant difference was observed in relation to pH values and the period of storage as follow: in the period of 1 (5.81 and 5.81), 30 (6.04 and 6.05), 60 (6.22 and 6.23), and 120 (6.30 and 6.30) days, respectively either for the meat of female turtle or male. There was not significant difference concerning to sex. As for total volatile bases (TVB), the period of storage has influenced significantly: in the period of 1 (11.34 and 11.74 g/100g), 30 (13.92 and 13.90 g/100g), and 120 (17.62 and 17.82 g/100g); in the period of 30 (13.92 and 13.90g/100g) and 60 (14.02 and 14.06g/100g) days, significant difference was not observed, respectively for female and male meat. Not significant difference occurred in relation to sex. The result for color, texture, scent, and cooking test did not present any alteration along the period of storage. The meat of turtle obtained a 7.04 average of general acceptability that shows the acceptance of the tasters for this sort of meat. According to the results for pH and TVB, we have concluded that this meat of turtle may have 120 days of commercial validity once it is vacuum-packed and stored at -100Celsius, and that it presents good acceptance for the tasters.
