    摘要:

    以秋富红苹果为试材,研究冷藏及同期冷藏后室温货架7 d果实品质及生理活性的变化。结果表明:秋富红苹果存在呼吸跃变,果实呼吸高峰出现于冷藏期第98天,及冷藏70 d室温货架7 d时;冷藏果实的多酚氧化酶活性较同期冷藏后室温货架7 d的低,过氧化物酶活性较同期冷藏后室温货架7 d的高,但均推迟活性高峰;冷藏期第126天和冷藏98 d后室温货架7 d的秋富红果实品质快速劣变,失重率急剧上升。综合果实生理品质变化结果,秋富红苹果冷藏适宜贮期为126 d,需室温货架7 d的果实适宜冷藏期为98 d。

    Abstract:

    Using the ‘Qiufuhong’ apples as the materials, the changes of fruit quality and physiology activity under cold storage and 7 days shelf-life after cold storage were studied. The result showed that, the ‘Qiufuhong’ apples had the respiration climacteric, the respiration climacteric of cold storage fruits happened at 98 days and the shelf-life fruits happened after 70 days cold storage, the cold storage fruits had the lower PPO activity and higher POD activity, and the activity peak were all delayed, the quality of ‘Qiufuhong’ apples became inferior and weight loss ratio enhanced quickly after 126 days cold storage and 98 days cold storage for shelf-life fruits. The best storage time for cold storage fruits was 126 days, and 98 days for shelf-life fruits.
