To enhance the cool storage effects by package with proper method,blueberries were packed with 0.02 mm PE film,0.05 mm PE film,atmosphere controlled box X-1,atmosphere controlled box X-2.The effect of fresh-keeping on blueberry during storage was studied.The result showed that the blueberries packed with different methods all had better results than the controlled group,the shelf life extended to 50 d when stored at(0±0.5)℃.Weight losses,soluble solids content(TSS),cell membrane permeability and rotting rate were different among different packaging treatment.Among these methods,controlled atmosphere box X-2 was the best.
