Description
Summary:Fish production has increased in Brazil, mainly the fresh-water aquaculture. However, refrigerated fish presents a relatively short shelf-life (approximately 12 days). In view of the increasing demand for fresh products, there is the need of shelf-life lengthening through a combination of methods in order to minimally expose the product to adverse conditions. The use of the modified atmosphere packaging presents the following advantages: lengthening of the products' shelf-life by 50 to 400%, reduction of economic losses, cost reductions by distributing the product over great distances with the need of fewer shipments and the supply of a better quality product. The purpose of this work was to review and discuss the major effects of the modified-atmosphere packaging, especially carbon dioxide (CO2), on seafood preservation, as well as on the survival and growth of seafood pathogenic organisms.<br>A produção de pescado vem crescendo no Brasil, principalmente a piscicultura de água doce, porém o pescado refrigerado tem uma vida útil relativamente pequena, cerca de 12 dias, e a demanda de produtos frescos é crescente, havendo, portanto, a necessidade de aumentar a vida útil destes, através da utilização de processos combinados, que exponham o mínimo possível o produto a condições adversas. O uso de embalagens com atmosfera modificada têm como vantagens potenciais: aumento da vida útil de 50 a 400%; redução de perdas econômicas; distribuição dos produtos a longas distâncias e com poucas remessas, diminuindo os custos; além do fornecimento de produtos de qualidade. Esta revisão teve como objetivo discutir os efeitos da atmosfera modificada na conservação do pescado, principalmente CO2, sobre o crescimento e sobrevivência de patógenos de origem alimentar.
