Abstract: The balance of the respiration of the vegetables and the permeation through the plastic films could be gotten in certain conditions and could spontaneously control the concentration of oxygen and carbon dioxide in the storage preservation bags. Thus, we designed the MAP for asparagus by means of changing the thickness (D), the area (A) and the storagen (W) of the films to control the gas composition inside the package. On the basis of a large amount of experiment data, a modified atmosphere storage package for asparagus was designed by computer regression, which could store asparagus in a fit composition of gas (3.2%～8.3% O2, 3.5%～5.3% CO2) and keep the asparagus fresh and delicious.

Key words: asparagus, MA(modified atmosphere), fit composition of gas, modified atmosphere storage package
