摘　　要：分别以30μm黄色聚氯乙烯保鲜袋、30μm白色聚乙烯保鲜袋和50μm白色聚乙烯保鲜袋为包装材料,研究了室温和4℃条件储藏期间薄壳山核桃坚果的生理及营养品质变化。研究结果表明,与对照相比,气调保鲜包装(MAP)能使包装环境内形成低O_(2)、高CO_(2)环境,有利于保持薄壳山核桃中的总脂肪、不饱和脂肪酸和γ-生育酚的含量,延缓其呼吸速率、酸价、过氧化值和皂化值的上升。在供试的3种气调保鲜包装中,以50μm白色聚乙烯保鲜袋的效果最好。In this paper,the physiological and quality changes of pecan nuts during storage at room temperature and 4℃were studied by use of 30μm yellow PVC bag,30μm white polyethylene(PE)bag and 50μm white PE bag were as packaging materials,respectively.The results indicated that compared with the control,modified atmosphere packing(MAP)could form low O_(2) and high CO_(2) environment inside the packaging,beneficial to maintain the contents of total fat,unsaturated fatty acid andγ-tocopherol,and delay the increase of respiration rate,acid value,peroxide value and saponification value.The package of 50μm white PE bag is the best in this experiment.
