Characteristics for a well-executed CA storage of apples are the preservation of quality, hardness, a fresh appearance and the prevention of internal and external defects.

In the (D)CA storage of apples, the focus is on controlling ultra-low oxygen values in combination with low CO2 values. Storex supplies CA technology with the most extensive process control technology for this.

(D)CA storage apples

Apples are generally very suitable for storage in gas-tight CA cold stores under controlled oxygen and CO2 conditions. Under these CA/ULO conditions, apples can be stored for up to 12 months! Apples remain in good condition at temperatures between 0 and 5 °C, depending on the variety.

By storing at a very low oxygen percentage ( DCA / ULO storage), ethylene production is kept low. The sensitivity of apples to ethylene is considerably lower under DCA / ULO.

Optimal storage conditions for apples

The optimal storage conditions for apples depend on the variety, time of harvest, region, soil type, growing conditions, etc. Based on research and practical experience, storage specialists for each region formulate recommendations for the optimal storage conditions. Information about CA conditions for the storage of fruit on this website are only indicative. Consult local CA consultants / research institutes for advice on setting the correct CA conditions for your situation.
