Abstract：Based on the principle of dynamic balance between the respiration of white asparagus（Asparagus officinalis L.）and permeability of the packaging film under a certain condition, the relationship between the 3 parameters（film area, film thickness and fruit storage weight）and the atmosphere（O2 and CO2）in EMAP was studied. The optimum atmosphere composition in EMAP that stored white asparagus at（3±0.5）℃, RH 90 %-95 % was determined through quality indicators and sensory evaluation at the end of the storage period. The optimum atmosphere composition was CO2：（5.9 %±0.3 %）, O2：（4.2 %±0.4 %）. Utilizing orthogonal experiment and multiple regression method, the EMAP for storing white asparagus has the advantages of low cost, simple operation, and good effect.
