摘　　要：以红熟期朝天椒为材料,结合自发气调包装(modified atmosphere packaging,MAP)和(9±0. 5)℃低温贮藏技术,研究了不同透气性参数的聚乙烯包装膜对朝天椒低温贮藏保鲜效果的影响。结果表明,MAP处理可有效降低朝天椒贮藏过程中的失重率,包装膜透气性参数对包装后朝天椒的贮藏品质影响具有明显差异。MAP处理中除E处理[包装膜O2和CO2透过率分别为1 865 cm3/(m2·24 h·0.1 MPa)和7 214 cm3/(m2·24 h·0.1 MPa)]加速了朝天椒的腐烂外,其他4个处理均能不同程度抑制朝天椒贮藏过程中组织相对电导率的升高,减少腐烂的发生,延缓外观品质的劣变。其中,C处理[包装膜O2和CO2透过率分别为8 087 cm3/(m2·24 h·0. 1 MPa)和31 520 cm3/(m2·24 h·0. 1 MPa)]在贮藏30 d时朝天椒商品性最好。The preservation effects of polyethylene( PE) packaging films with different gas transmission rates to postharvest red cayenne pepper( Capsicum annuum var. conoides) were studied using modified atmosphere packaging( MAP) at( 9 ± 0. 5) ℃ cold storage. The results suggested that PE packaging films could effectively restrain the weight loss of red pepper during the cold storage,while MAP treatments with different O2/CO2 permeability differed on the fresh-keeping effect significantly. All treatments maintained the appearance by inhibiting the increase of red pepper in electrolyte leakage and rot,except the treatment E [the permeability of O2 and CO2 is 1 865 cm3/( m2·24 h·0.1 MPa) and 7 214 cm3/( m2·24 h·0.1 MPa) respectively]which accelerated the decay of red pepper. In addition,compared with others,treatment C [the permeability of O2 and CO2 is 8 087 cm3/( m2·24 h·0.1 MPa) and 31 520 cm3/( m2·24 h·0.1 MPa) ]had the best commercial quality after 30 days of cold storage.
