Abstract
O experimento teve por objetivo avaliar a influência das altas concentrações iniciais de CO2 sobre os aspectos físico-químicos de maçãs 'Golden Delicious' armazenadas em atmosfera controlada. Os tratamentos foram 10% de CO2 e 5% de O2 e 15% de CO2 e 5% de O2 durante 5, 10 e 15 dias, sendo que durante o restante do período de armazenamento os frutos foram armazenados em 4% de CO2 e 1,5% de O2, na temperatura de +0,5 °C e umidade relativa de 97%. Após 10 meses, não foi verificado diferenças significativas na firmeza de polpa, acidez titulável, sólidos solúveis totais e controle de podridões. Na abertura das câmaras os tratamentos iniciais com CO2 não mostraram influência na degenerescência da polpa e escaldadura, porém, após 14 dias todos os tratamentos com CO2 aumentaram a incidência de degenerescência interna e tratamentos com 15% de CO2 diminuíram ligeiramente a ocorrência da escaldadura.
The aim of this experiment was to evaluate the effect of initial high CO2 concentrations on quality of 'Golden Delicious' apples stored in controlled atmosphere. The treatments were 10% of CO2, and 5% of O2, and 15% of CO2, and 5% of O2, during 5, 10 and 15 days but during the remaining of storage time fruits were kept in 4% of CO2, and 1.5% of O2, at +0,5 °C and 97% RH. After 10 months, no diferences in firmness, total soluble solids contents, acidity and decay were observed. At opening of controlled atmosphere chambers CO2 treatment had no influence in internal breakdown and scald, but after 14 days in shelf-life. all treatments with high CO2 increased internal breakdown and 15% of CO2 decreased scald incidence.
