Isolcell ISOSTORE© System Practical advantages of DCA-CF
Reduce costs, times and post-harvest chemicals No risk of fermentation Increased fruit quality Very User friendly Measurement system operates continously Totally computerised No risk for the operator Main Advantages of DCA-CF
Increased pack out
Reduced rots and damage to fruit
Reduction of internal browning
Increased colour retention, firmness and flavour
Longer shelf-life
Scald control without POST HARVEST chemical treatments = Advantage in EXPORT and ORGANIC MARKETS . Moving forward
. Energy conservation
• DCA-CF substantially reduces fruit respiration, with the result that equipment works less and also higher storage temperatures are possible; thus saving energy
. More realtime information
• New technologies being incorporated to monitor other quality parameters of stored fruit.
. New varieites and other products
• DCA-CF used extensively to determine storage parameters and regimes of new varities.
• DCA-CF successfully being trialed on GOLD Kiwi. 2019 was the year of Aussie visitors SAVE THE DATE
