| description | Sodium metabisulfite is the main additive used in the prevention of melanosis in shrimp; however, it has currently been employed with great variation in concentration by producers. Thus, the aim of the present study was to determine the correlation between the concentration of the sodium metabisulfite solution and immersion time of the whole shrimp to obtain the concentration of sulfur dioxide (SO) in the edible muscle of farmed shrimp (Litopenaeus vannamei) in accordance with the limit established by law. For this, solutions of sodium metabisulfite at different concentrations (1%, 2 %, 3 %, 4% and 5%) were prepared and samples of L. vannamei shrimp (100g) were immersed during 10, 20 or 30 minutes at temperature of 7°C. For all treatment assayed the concentration of S[O.sub.2] was determined in the edible muscle of farmed shrimp (L. vannamei). The results show that for the conditions used in this study, the correlations were linear, with significant increase (P |

Os resultados demonstraram que, para as condicoes empregadas nesta pesquisa, as correlacoes encontradas foram lineares, ocorrendo um aumento significativo (P<0,05) nos teores de S[O.sub.2] no musculo comestivel do camarao, tanto com o aumento da concentracao das solucoes de metabissulfito de sodio, quanto com o aumento no tempo de imersao, sendo possivel sugerir a imersao dos camaroes em solucao a 3% por um tempo de 13 minutos, de forma a se obter, em seu musculo comestivel, a concentracao de 100ppm de S[O.sub.2], de acordo com o recomendado pela legislacao brasileira.
