摘　　要：目的探究不同自发气调袋(WK、PE20、PE30和PE40)对玛瑙红樱桃在贮藏期间外观品质和生理生化指标的影响。方法以玛瑙红樱桃为材料,采用不同自发气调袋对其进行包装,贮藏至(1±0.3)℃环境中21 d,每隔7 d测定一次玛瑙红樱桃相关指标,研究贮藏期间自发气调袋内玛瑙红樱桃的品质变化,以探寻其最佳贮藏包装条件。结果随着贮藏时间的延长,PE包装贮藏能有效降低果实的腐烂率,抑制呼吸强度和可溶性固形物(Soluble Solids,TSS)含量的增加,维持了较高的果实硬度,提高果实品质和营养价值。其中,PE20包装贮藏显著延缓了果实维生素C和多酚含量的下降,抑制了丙二醛(Malondialdehyde,MDA)的积累,并保持了较高的过氧化物酶(Peroxidase,POD)活性。此外,主成分分析(PCA)综合得分表明,在玛瑙红樱桃贮藏过程中,PE20包装具有最佳的综合效果。结论玛瑙红樱桃的低温贮藏过程中,PE20包装最为有助维持果实的贮藏品质。The work aims to explore the effects of different modified atmosphere packaging(MAP)bags on the appearance quality and physiological and biochemical indices of manaohong cherries(Prunus pseudocerasu L.)during storage.Manaohong cherries were packaged with different MAP bags and stored at(1±0.3)℃for 21 d.The relevant indices of the cherries were measured every 7 d to study the changes in quality within the MAP bags during storage and to identify the optimal storage packaging conditions.As the storage period extended,storage in PE packaging effectively reduced the fruit decay rate,suppressed the increase of respiration rate and soluble solids content(TSS),and maintained high fruit hardness,thus improving fruit quality and nutritional value.Specifically,PE20 packaging significantly delayed the decline in vitamin C and polyphenol content,inhibited the accumulation of malondialdehyde(MDA),and maintained high peroxidase(POD)activity.Additionally,principal component analysis(PCA)composite scores indicated that PE20 packaging exhibited the best overall effect during the storage of manaohong cherries.During the low-temperature storage of manaohong cherries,PE20 packaging is the most effective in maintaining the storage quality of the fruit.
