Storage of 'Chimarrita' peach in controlled atmosphere and under ethylene absorption

Two experiments were carried out with the objective to evaluate the effects of two forms of ethylene absorption and controlled atmosphere (CA) storage on the quality of 'Chimarrita' peaches. The treatments of the first experiment were: control (cold storage); 1kPa O2/3kPa CO2; e 5kPa O2/10kPa CO2. In the second experiment the same treatments were combined to ethylene absorption; either absorption using a filter or absorption using a sachet and no absorption at all. In both experiments, the fruits were stored at -0,2ºC for 45 days. At retrieval from storage, CA conditions maintained higher titratable acidity and reduced decay incidence and pathogen sporolution. After two days at 20ºC, the fruits stored in CA were firmer had less decay and sporolated lesions. Fruits stored in 5kPa O2/10kPa CO2 had higher wooliness incidence. In experiment 2, the ethylene absorption was not effective for quality maintenance of 'Chimarrita' peaches, but after 2 days at 20ºC, fruits stored with ethylene absorption were less decayed.
