Effect of pre-cooling on qualities of strawberry during logistics
[Objective]The objective of the study was to clarify the quality loss of strawberry.[Method]Effect of pre-cooling treatments on qualities of strawberries (Fragaria ananassa Duch.‘Benehoppe') was studied during logistics.[Results]Results showed that immediate pre-cooling at 0 ℃ could keep the environment temperature of strawberry less than 10 ℃ during 14 h of logistics transportation at normal temperature,which achieved the requirements of the food cold chain logistics,but immediate or delayed precooling at 5 ℃ could not.Immediate or delayed pre-cooling at 0 ℃ treatment could also realize that the water loss in strawberry packaged with plastic tray was 2％ lower,and 0.5％ lower in strawberry packaged with modified-atmosphere box.Immediate,delayed pre-cooling at 0 ℃ and immediate pre-cooling plus modified-atmosphere box treatment could inhibit the disease incidence (＜ 5％) after 3 d of storage at 0 ℃,7 ℃ or 20 ℃.[Conclusion]Pre-cooling treatment at 0 ℃ can significantly reduce the quality loss of strawberry during transportation and storage loss.
