Effect of high CO2 and controlled-atmosphere storage on the keepability of blackberry cv. "Thornfree".

Author(s) : AGAR I. T., STREIF J., BANGERTH F.

Summary

In two years, storage trials with blackberry cv. Thornfree: a) cold storage; b) high CO2 treatments + cold storage (5-30% CO2, without O2 control); c) high CO2 treatments + low O2 treatments + cold storage (2% O2, controlled-atmosphere experiment), were investigated. Blackberries were harvested at commercial maturity in 250 g punnets and analysed every 3 days and after a day of shelf life in 20 deg C for the following quality parameters: total soluble solids, titratable acidity, berry colour, vitamin C content, ethanol and acetaldehyde content and CO2 production rate. Blackberries tolerate relative high CO2 concentrations for transport and short-term storage (over the weekends) and they can be stored in 0-2 deg C in 20-30% CO2 for 6 days with sufficient shelf-life. Controlled-atmosphere storage was not found very advantageous in comparison to high CO2 treatments.
