Abstract: The purpose of this study was to investigate the effect of packing film permeability on short-term spontaneous gas regulation(MAP)storage of chives under low temperature(1±0.5 ℃). In this article,five types of gradient oxygen and carbon dioxide permeability polyethylene film bags were used to pack the chives,and the changes of some physical and chemical indicators of the chives after storage were tested. These indicators included the sensory indicators,decay index,gas composition,relative conductivity,tissue water content,malondialdehyde,and solubility sugar and ascorbic acid content. The results showed that the O₂ and CO₂ gas permeability were(4623±834) cm³/m²·24 h·0.1 MPa and(18033±3356) cm³/m²·24 h·0.1 MPa in polyethylene packaging bags after MAP treatment,the content of O₂ and CO₂ in the packaging bag was maintained at 11.67%~13.67% and 2.43%~3.45% relatively stable state when stored for 28~42 days. Using this packing bag could delay the increase of chives rot index,relative conductivity and malondialdehyde content in the storage process,slow down the decrease of sensory index,tissue moisture content,soluble sugar and ascorbic acid content,and the packaging film could be used as an appropriate MAP treatment material combined with refrigeration technology to prolong the fresh life of chives after harvest.
