Why DCA-Storage Technology makes sense ? MSc. Fabio Thewes Main reason is: to avoid the physiolgical diseases like: A) Flesh breakdown B) Superficial scald C) Skin spots “Elstar“ FruitAtmo - New DCA Storage Technology

11 FruitAtmo - New DCA Storage Technology
Why DCA-Storage Technology makes sense ? Possitive side effects: Higher fruit quality as: a) Flesh firmness b) Acidity c) Less sensitivity for bruising d) Higher aroma compounds Reduce fruit respiration and ethylene production e) Lower CO2- Adsorber running times f) Better shelf life after storage FruitAtmo - New DCA Storage Technology

16 FruitAtmo - New DCA Storage Technology
What is new about FruitAtmo DCA-method ? The FruitAtmo Method is based on CO2 – Production only. Invented by team Thewes , Brackmann, Schmidt of University Federal de Santa Maria, Brazil in co-operation with KOB Bavendorf , Germany. FruitAtmo - New DCA Storage Technology

17 FruitAtmo - New DCA Storage Technology
What is the idea behind FruitAtmo ? The CO2 release is the most important indicator of fruit metabolism. The CO2 release decreases as the O2-Level is lowered in the CA-room, until the anaerobic compensation point (ACP) is achieved. If the O2-Level is lower than the ACP-Point, then the CO2 release increases sharply. Taking this in account, the response of CO2 releases to the O2 lowering the correct oxygen. Setpoint can be monitored by the CO2-release with a special algorithm over the storage period. FruitAtmo - New DCA Storage Technology

18 FruitAtmo - New DCA Storage Technology
What does it means in practise ? The System does not require any additional equipment to be used in a commercial CA-room. - The measurement of O2 uptake is not nessary to determine optimal O2 setpoint. - The System adapts the Oxygen set point of each Varity, species, maturity stage automatically, like a self-learning system. - The system runs completely autonomous, no interpretations are necessary. Optimum correct O2 setpoint will calculated automatically over the storage period. FruitAtmo - New DCA Storage Technology

27 FruitAtmo - New DCA Storage Technology
For which varieties FruitAtmo works ? 1) It works well with the following apple varities:     ==> Gala, Fuji, Red Delicious, Royal Gala, Galaxy, Maxi Gala, Pink Lady, Imperial Gala, Golden Delicious, Elstar, Red Prince, Shalimar, Jonagold, Granny Smith, Kanzi (only for 6 month‘s storage), Fuji Suprema and Fuji Kiku. 2)  Does not work well for the following varities:     ==> Kanzi apples stored for a longer period of – 6 months. 3)  Not tested yet, but may work well on:     ==> Pinova, Braeburn, Empire, Cameo, Envy, Jazz, Jonathan, McIntosh, Daiane, etc. FruitAtmo - New DCA Storage Technology

How will FruitAtmo be intergrated in CA-Systems? FruitAtmo - New DCA Storage Technology

29 FruitAtmo - New DCA Storage Technology
What will be the next development with FruitAtmo ? On the same CO2 release measurment of fruits, the algorithm is also able to find the: optimum temperature setpoint ! That means is practice: The room temperature setpoint could be raised between 0,5 to 2,0 K to the Standard value: energy savings in refrigeration system - reducing losses because of low temperature damages The temperature setpoint interacts with the O2 setpoint - this will be done automatically. Tests were successfully done and more tests are in the planning: Temp.Control will be ready in the next year. FruitAtmo - New DCA Storage Technology

FruitAtmo, Summary of Advantages: 1) To employ the new DCA method in commercial rooms, it is not necessary for any additional equipment - reducing the cost for its adoption in commercial rooms; 2) With the use of the new DCA method, the oxygen uptake measurement is not necessary to estimate the lowest oxygen limit; 3) During the period, that CO2 scrubber is turned-off to allow the accumulation of CO2 in the storage room is not necessary turn-off the oxygen injection. This is very important to avoid low oxygen stress; 4) The new DCA method gives the new oxygen setpoint, without needing interpretations, as is necessary for other DCA methods; 5) The new DCA method allows the induction of anaerobic metabolism at safety levels. The induction of anaerobic metabolism results in acetaldehyde and ethanol production by fruit. Compounds that suppress the ethylene biosynthesis, increase the aroma production of fruit and prolong the shelf life of the product; FruitAtmo - New DCA Storage Technology

FruitAtmo, Summary of Advantages: 6) With the employment of the new DCA method all fruit of the room are monitored and not only samples, as in DCA – CF and some methods of DCA – RQ, resulting in more realistic results; 7) The new DCA method allows the calculation of a factor, which gives evidence about fruit metabolism and consequently if the low oxygen is effective to reduce respiration; 8) The new DCA method avoids the occurrence of superficial scald on apples by the low oxygen and ethanol accumulation; FruitAtmo - New DCA Storage Technology
