• Abstract:

  The tambaqui Colossoma Macropomum (CUVIER 1818) is a fish with potential for zootechnical production, using the modified atmosphere packaging method (EAM). EAM consists of replacing the atmosphere around the product in packaging with gases such as CO2, N2 and O2. The tambaqui used was produced in a Biofloc Technology system (bioflocs), until it reached a size of 400g, called "curumim". Three treatments were carried out: A (control), B (100% CO2) and C (vacuum). The samples were packaged and kept refrigerated at 2 ± 1°C, being subjected to analysis at times 0, 1, 7, 14, 21 and 30 days of refrigerated storage. Physicochemical parameters such as pH, N-BVT, TBA were evaluated, in addition to microbiological analyses. On the 30th day of storage, the treatments exceeded the microbiological limit established by legislation (7 Log CFU/g). During the storage period, the presence of Salmonella or E. coli was not detected. TBA indices remained below 1.5 mg MA/kg. It is concluded that atmosphere C (vacuum) and 100% CO2 stood out compared to the control aerobic treatment, extending the useful life by up to 21 days, being effective in maintaining physical-chemical and quality parameters within acceptable limits. established by legislation.
