In this context, Fruits, which were harvested optimum harvest date, were treated with SencyFresh™ [0 (control), 625 ppb (0.042 g/m3), 1250 ppb (0.084 g/m3)] at 10°C for 24 h following harvest then fruits were stored in regular atmosphere (RA) at 0±0.5°C and 90±5% RH for 6 months. Fruits, which removed from cold storage for each month and stored shelf life (at 20°C and 60±5% RH for 7 days), quality was analyzed. Under RA conditions both concentrations of SencyFresh™ maintained firmness and titratable acidity, suppressed ethylene production, reduced respiration rate for 6 months compared to the control treatment.
