Quality of 'Isabel' grape treated with calcium chloride in postharvest and stored under modified atmosphere/Qualidade de uva 'Isabel' tratada com cloreto de calcio em pos- colheita e armazenada sob atmosfera modificada

'Isabel' grapes were treated postharvest with calcium chloride (Ca[Cl.sub.2]) and in modified atmosphere (MA) aiming its quality maintenance during storage at 12 ± 1 °C and 85 ± 2% RH. The experiment was carried on a completely randomized design, in a factorial scheme 5 x 2 x 5 with three...

Zusammenfassung:'Isabel' grapes were treated postharvest with calcium chloride (Ca[Cl.sub.2]) and in modified atmosphere (MA) aiming its quality maintenance during storage at 12 ± 1 °C and 85 ± 2% RH. The experiment was carried on a completely randomized design, in a factorial scheme 5 x 2 x 5 with three replications, with five levels of Ca[Cl.sub.2] (0,0; 0,5; 1,0; 2,0 and 4,0%), two types of atmosphere [room and modified atmospheres (MA)] and five evaluations, during cold storage. The evaluations were titratable acidity (TA), soluble solids (SS), SS/TA ratio, pH, ascorbic acid, decay incidence, mass loss, rachis appearance, and berry drop index. MA reduced mass loss, incidence of decay, and maintained the green rachis appearance. Ca[Cl.sub.2] doses among 0,5 and 2,0% reduced decay incidence. The application of Ca[Cl.sub.2] associated with MA reduced berry drop index in 'Isabel' grape during cold storage.
