Armazenamento de maçã 'gala' em atmosfera controlada com remoção de etileno Storage of 'gala' apple in controlled atmosphere with removal of ethylene

Abstract

O objetivo deste trabalho foi avaliar o efeito de diferentes níveis de etileno na câmara sobre a manutenção da qualidade da maçã cv. Gala, durante o armazenamento em AC. O delineamento experimental utilizado foi inteiramente casualizado com quatro repetições e a unidade experimental composta por 50 frutos. Os tratamentos utilizados foram: >10µl L-1 (sem absorção); The objective purpose of this work was to evaluate the effect of different ethylene levels on the quality of cv. Gala apples during CA storage. The experimental design was completely randomized with 4 replications of 50 fruits. The treatments were: >10µl L-1 (without absorption); < 0.4µl L-1 and < 0.04µl L-1. After 8 month storage, at the chambers opening and after 7 days shelf life at 20ºC fruits with ethylene absorption had higher firmness and titratable acidity and lower rot and senescent breakdown incidence. There was no statistic difference between treatments for TSS. After 7 days shelf life ground color was greener on the fruits stored with ethylene absorption. Mealy fruits incidence was lower with ethylene absorption, at the chambers opening.
