Comparison of physiochemical changes in two popular strawberry cultivars grown in Iran (cvs. Kurdistan & Selva) during storage time at 4°C

In this study the effect of storage time on some quality parameters of two strawberry cultivars fruits storage at 4°C have been evaluated. Several quality parameters were monitored during the storage period. The samples were analyzed 1, 7, 14 and 21days during storage. Fruits were analyzed about fruit weight, sugar content, chromatic parameters L*, a*, b*, fruit firmness, total titrable acidity, pH, and sensory evaluation. The Kurdistan strawberries retained their weight throughout the experiment as opposed to the Selva strawberries which lost 0.6% of their weight per day because of dehydration. The Selva cultivar was exceptionally firmer than Kurdistan strawberries. Two cultivars were rich in vitamin C and sugar but these values were more in Kurdistan cultivar. As expected, Chroma decreased and over the storage time in two cultivars. The results of this study showed that packaged Kurdistan strawberries could prove suitable for 7 days at 4°C compare with 4 days for selva strawberries
