Effects of ozone treatment on postharvest strawberry quality.

The effect of ozone treatment on the postharvest quality of strawberry fruits was evaluated. Fruits (cv. Camarosa, grown in Spain) were stored at 2 deg C in an atmosphere containing ozone (0.35 ppm). After 3 days at 2 deg C, fruits were moved to 20 deg C to mimic retail conditions (shelf life). Changes in several quality parameters including fungal decay, colour, distribution of sugars and acids, and aroma were evaluated. Ozone treatment was ineffective at preventing fungal decay. Significant differences in sugar and ascorbic acid contents were observed between control and ozone-treated fruits. At the end of cold storage, the vitamin C [ascorbic acid] content of ozone-treated fruits was 3-times that of control fruits. Ozone treatment was detrimental to strawberry aroma, and reduced emissions of volatile esters by 40%.
