The efficacy of different postharvest treatments on physico-chemical characteristics, bioactive components and microbiological quality of fresh blueberries during storage period

In recent years, there is increasing consumption and interest in berry fruits in general and blueberries in particular due to their nutritional and health characteristics. However, blueberries are highly susceptible to microbial contamination and loss of product quality. In this study, the effects of postharvest washing treatment and cold storage (15 days) on the quality of blueberries were examined. The blueberries were treated with mineral water, aqueous chlorine dioxide, electrolyzed water and Berry Very®, a new commercial product. During the storage, physicochemical and microbiological analysis were carried out in order to compare the efficacy of treatments. The results indicated that chlorine dioxide treatment and electrolyzed water had a positive effect on the reduction of yeast and mold proliferation, postharvest decay and weight loss
