| Summary: | The objective of this work was to evaluate the quality and conservation of strawberries in modified atmosphere. ‘Oso Grande’ strawberries, produced in Botucatu-SP-Brazil, and picked in the ¾ red maturation stages were used. The experiment consisted in the storage of the fruits in polyethylene packages under different gaseous mixtures: control; vacuous; 5% O2 and 1% CO2; 5% O2 and 3% CO2; 5% O2 and 5% CO2. The analyzed parameters were: appearance, shelf life, incidence of disease, soluble solids, titratable acidity, vitamin C and firmness. For evaluation of the post-harvest conservation the fruits were stored in 0o C +/- 1o C / 90 +/- 5% UR ambient for 12 days and appraised every 2 days. The statistical layout was completely randomized, by comparing the means with Tukey test in a ratio of 5% probability. The obtained results allow to conclude that the fruits of the treatment testify didn’t present statistical differences of the other treatments except the one of vacuous partial.<p><p>Este trabalho teve como objetivo avaliar a qualidade e a conservação de morangos armazenados sob atmosfera modificada. Foram utilizados morangos ‘Oso Grande’, produzidos na cidade de Botucatu-SP e colhidos no estádio de maturação ¾ vermelho. O experimento constituiu no armazenamento das frutas em embalagens de polietileno sob diferentes misturas gasosas: testemunha; vácuo parcial; 5% O2 e 1% CO2; 5% O2 e 3% CO2; 5% O2 e 5% CO2. Os parâmetros analisados foram: aparência, vida útil, incidência de doenças, teor de sólidos solúveis, acidez titulável, vitamina C e firmeza.. Para a avaliação da conservação pós-colheita, os frutos foram armazenados a 0o C +/- 1o C / 90+/-5% UR por 12 dias e avaliados a cada dois dias. O delineamento estatístico adotado foi o inteiramente casualizado, comparando as médias pelo teste de Tukey a 5% de probabilidade. Os resultados obtidos permitem concluir que as frutas do tratamento testemunha não apresentaram diferenças estatísticas dos demais tratamentos exceto o de vácuo parcial. |
