Inhibitory effects of the ethylene chemisorption on the climacteric of cherimoya fruit in modified atmosphere.

Cherimoya (cv. Fino de Jete) fruits were packaged in plastic boxes containing ethylene absorbent (Green Keeper at 0, 3.5, 5.0 or 7.0 g/kg), enclosed in polyethylene bags and stored at 8.5 deg C and 98% RH. Gas samples from the atmosphere inside the bags were analysed daily by GC for CO2 and ethylene. Flesh firmness, internal colour, reducing sugars, soluble solids and titratable acidity were determined throughout the storage period. The ethylene peak occurred on day 18 for control fruits (no ethylene absorbent) and fruits with 5.0 g absorbent/kg and one week later for fruits with 3.5 and 7.0 g absorbent/kg. Softening of the fruits followed these increases in ethylene production and was accompanied by a continuous rise in CO2. Fruits stored with 3.5 g absorbent/kg showed significantly reduced respiration rates and ethylene synthesis; weight losses were reduced during the optimal storage period of 18 days.
