1 Harvest & Post Harvest Handing of Blueberries for Fresh & IQF Markets Charles F. Forney Kentville Research and Development Centre

2 Factors Affecting Fruit Quality and Market Life Fruit Quality Cultural practices/environment Harvest factors Packing and handling Temperature management Storage environment

3 Fruit Quality Parameters Size Color Bloom Firmness Defects Flavor

4 IQF Fruit Quality CFIA Grade A fruit Good flavour of well-ripened blueberries Uniform colour Good condition Free from cap stems Free from defects Clusters, Leaves, Stems, Green berries, Extraneous material Good condition-avoid splits Loss of sugars Toughening Increase drip loss upon thawing

5 Postharvest Quality Loss Mechanical damage Shrivel/water loss Decay Physiological breakdown Loss of flavor

6 Importance of Initial Fruit Quality Determines fruit marketability potential market life Fruit quality can not be improved postharvest

7 Shrivel Dehydration Overripe Split Mechanical damage Excess water Decay Insect/bird damage Decay Defects

8 Genetic Effects - Cultivars Marketable fruit (%) weeks 0 C 3 C 40 Burlington Nelson Elliot Brigitta Jersey Coville Cultivar

9 Genetic Effects - Cultivars Marketable fruit (%) weeks 0 C 3 C 40 Burlington Nelson Elliot Brigitta Jersey Coville Cultivar

10 Genetic variability Wild fields V. angustifolium Aiton ~95% of wild fields V. myrtilloides Michaux Clonal differences Determine storage potential ~109 different clones/acre V. angustifolium V. myrtilloides

11 Fertility Cultural Practices/Environment Pollination Field cleanliness Weed control Debris Rainfall Temperature Stress - Biotic - Abiotic

12 Fruit maturity Harvest Factors Environment Method

13 Quality Changes during Ripening on the Plant Firmness Declines rapidly during color development Titratable acids Declines during color development and further ripening Soluble solids Increases during color development and further ripening Firmness (g/mm) TA SS SS/TA 0 white Ripeness (days following color turning) Ripeness (days following color turning)

14 Harvest Timing Wild Blueberries Once-over harvest Challenge of determining optimum harvest window Fruit ripen unevenly Within plants Among clones Ripening rate influenced by biology/environment Pollination Position on stem and in cluster Temperature Sunlight Moisture availability

15 Harvest Window Temperature most important factor Growing degree day (GDD) model Predict harvest window GDD = (max C + min C)/2 5 C First ripe fruit ~650 GDD Maximum ripe fruit 1100 GDD GDD after first ripe fruit (~6 weeks) 2 week harvest window Composition of ripe fruit did not change Soluble solids, Acidity, ph, Total Anthocyanins, Total Phenolics

16 Harvest Window Eaton 2009

17 Harvest Environment Rain Fruit turgidity Splitting Time of day Dew Temperature

18 Harvest Dry Fruit Wet fruit and debris stick together Reduced efficiency picking in wet fields Slower cleaning and sorting Greater susceptibility to splitting Free water on fruit encourages decay

19 Harvest Time - Temperature Fruit temperature Harvest at cool times of day Hot fruit Softer More prone to mechanical damage Avoid solar exposure Provide shade Cover fruit with reflective tarps Minimize time in field Cool within an hour of harvest

20 Harvest Method Minimal damage - high quality fruit Hand harvested fruit has longer storage life. Field packing may result in longer storage life Must ensure quality

24 Physical Abuse Wild Blueberries Fruit dropped onto hard surface Stored 14 days 0, 5, 10 and 20 C Percentage Marketable Split Shrivel Decay Average of all 4 temperatures Drop (cm) Sanford et al. 1989

25 Harvest Method Wild Blueberries Machine harvesters Tractor driven Walk-behind Hand harvest Rakes

26 Packing and Handling

27 Physical Abuse during Packing and Handling Physical abuse of fruit reduces potential storage life Every bounce, bump, drop or squeeze Greater force equals more damage Each physical abuse is cumulative Harvest, packing and handling must be designed to minimize abuse of fruit

28 Washing Wet Handling Reduces marketlife of fresh fruit Stored 14 days at 0, 5, 10 and 20 C Washed Unwashed Increases fruit splitting Percentage Firmness (N) Decreased fruit firmness Marketable Split Shrivel Decay Firmness Sanford et al. 1989

29 Field Packing Pack directly into punnets Least handling of fruit Pick into field containers Grade, sort and pack in field

30 Shed Packing Packing Line Automation Less labour Better quality control Sizer Color sorter Defect detection Punnet filling More abuse Reduces storage life Feed belt Punnet filler Sizer

31 Quality Loss during IQF Processing Fruit firmness decreased during processing Production stage Average % change* Firmness Splits Initial quality 36.9 N 33% Lug feed Splits increased Varied 7 to 576% among plants Winnower Raw to pre-freeze *Average of 10 processing plants Rodgerson et al. 1993

32 Cumulative Drops in IQF Processing Rodgerson et al. 1993

33 Minimize mechanical damage Reduce drops and hard impacts Keep equipment clean Process dry fruit Cleaning / Grading

34 Physical protection Low profile reduce compression Ridged sides/top Plastic Clamshells Packaging Adequate ventilation Breathable films Reduce water loss 34

35 Temperature Management

36 Harvested Fruit Are Alive Respiration CHO + O 2 CO 2 + H 2 O CO 2 CO 2 O 2 O 2 H 2 O H 2 O Respiration Transpiration 36

37 Temperature - Respiration Respiration Rate (mg kg -1 h -1 ) Heat Produced (BTU T -1 d -1 x 1000) Temperature ( C) 37

38 Temperature Forced Air Cooling Highbush blueberry - An 8 h delay resulted in: Reduced firmness* Increased weight loss* Increased split and decayed fruit* *following storage Wild blueberry delay cooling Reduced firmness & marketable fruit Increased split fruit Forced air cooling is recommended method Firmness (g/mm) % Split Cooling delay 20 C) Split Firmness Cooling delay 5-26 C) Jackson et al Firmness (N)

39 Forced Air Cooling Main Components Venting Fan Cold Air

40 Tunnel Cooler Forced Air Cooling

41 Cold-Wall Cooler Forced Air Cooling

42 Storage Temperature 0 to -1.0 C Maximize storage life Avoid freezing fruit Freezing point ~1.6 C

43 Storage Temperature Wild Blueberries Stored 14 days 0, 5, 10 and 20 C Fruit dropped - 0, 53, 106 or 159 cm Percentage Marketable Split Shrivel Decay Average of all 4 drops Storage Temperature ( C) Sanford et al. 1989

44 Benefits of Atmosphere Modification Carbon dioxide (10% + CO 2 ) Inhibits Botrytis Reduces Grey Mold Water vapor (H 2 O) Reduces weight loss Minimizes shrivel Slows compositional changes

45 Applying Atmosphere Modification Target atmosphere 10-12% CO % O 2 Avoid low O 2 <2% O 2 may cause fermentation Application CA rooms - not practical CA tents / pallet bags MAP

46 Blueberry Storage Pallet Racking CA Tents Zipper Pressure Relief Valve Sealed Tent Water Trough Open Door Loaded Pallet

47 Active Atmosphere modification Micro CA Pallet Storage Control Systems Palliflex system Van Amerongen

48 Passive Atmosphere modification Tectrol system TransFresh View Fresh Spectrum-Slider MAP bag

49 Conclusions Challenges / Opportunities Optimize fruit quality production practices & harvest timing Minimize mechanical damage during harvesting, cleaning, grading and packaging Cool and maintain optimum temperature (0 to 4 C) Use packaging that minimizes mechanical damage and reduces water loss Consider atmosphere modification to extend market-life
