    摘要:

    為探討1-MCP處理結(jié)合冰溫貯藏對采后葡萄果實質(zhì)地的影響,以乍娜葡萄為試材,應(yīng)用質(zhì)構(gòu)儀質(zhì)地多面分析(TPA)方法對葡萄貯藏期間果肉質(zhì)地參數(shù)變化規(guī)律進行研究。結(jié)果表明,1.0μL/L 1-MCP處理結(jié)合冰溫貯藏可以延緩葡萄果實的軟化,果實的硬度、彈性、凝聚性和咀嚼性較之單純的冷庫和冰溫貯藏均有所提高;果肉硬度與回復(fù)性呈較好的正相關(guān)性,果肉彈性與果肉回復(fù)性、咀嚼性、凝聚性均呈現(xiàn)較好的相關(guān)性;葡萄好果率與果肉硬度在一定范圍內(nèi)呈良好線性關(guān)系。結(jié)果也表明,TPA測試能夠較好地反映葡萄貯藏期間果實質(zhì)地的變化,適用于葡萄貯藏品質(zhì)的客觀評價。

    Abstract:

    In order to investigate the effect of 1-methylcyclopropene combined with controlled freezing-point storage on grape texture, the change of ‘ZANA’ grape flesh texture parameters was studied by using texture profile analysis with a texture analyzer. The result showed that softening of grape fruit was delayed by 1.0 μL/L 1-methylcyclopropene combined with controlled freezing-point storage. The hardness, springiness, cohesiveness, chewiness and marketable fruit rate of grape fruit treated by 1-methylcyclopropene are higher than cold storage and controlled freezing-point storage. The hardness of grape has a good positive correlation with resilience. The springiness of grape has good positive correlations with resilience, chewiness and springiness. The marketable fruit rate of grape has a good linear relationship with fruit hardness. In conclusion, TPA test can reflect the change of grape fruit texture during storage and fit for evaluation of the quality of stored grape.
