Summary

The study was aimed at testing the hypothesis that water temperatures less than the lowest recommended storage temperature (10 °C) for cucumbers could be used for hydrocooling without inducing chilling injury or negatively affecting storage life. Field cucumbers were hydrocooled with water at 1.5, 3.5, 6, 8 or 10.5 °C until the internal cucumber temperature reached 12 °C, or hydrocooled with water at 1.5 ° C until the internal cucumber temperature reached 1.7, 8 or 12 °C. Little or no visual symptoms of chilling injury were observed after 10-12 days of storage. However, chlorophyll fluorescence measurements indicated some chilling stress at the membrane level in cucumbers hydrocooled with water at temperatures below 6 °C and in cucumbers hydrocooled with water at 1.5 °C. Results suggest that cucumbers could be hydrocooled using water at temperatures below the recommended storage temperature of 10 °C. However, it is not recommended to use water below 6 °C or to cool the cucumbers below this temperature, due to increased risk of chilling injury as indicated by the chlorophyll fluorescence measurements.
