中文摘要:
      在冷藏运输过程中,温度波动会明显影响猕猴桃的品质和贮藏过程,确保稳定的运输 温度是提高冷藏运输猕猴桃的关键。将猕猴桃在2 ℃(0 ℃),2 ℃(1.5 ℃),2 ℃(3 ℃)不同温度波 动下冷藏运输24 h后,分别放在0 ℃、3 ℃和20 ℃下进行贮藏,探究温度波动对猕猴桃品质变化的 影响。通过测定猕猴桃的失重率、果实硬度、可滴定酸、可溶性固形物、叶绿素、丙二醛含量 (MDA)、Vc含量等指标,得到了温度波动对猕猴桃品质的影响规律。经过16 d的连续测量发现,在 贮藏温度为0 ℃时,温度波动为3 ℃的猕猴桃硬度变化是温度波动为0 ℃的1.94倍,是温度波动为 1.5 ℃的1.27倍。温度波动加剧了猕猴桃品质的衰变,温度波动越大,对猕猴桃品质的影响也越 大;贮藏温度也对其有一定的影响,贮藏温度越高,猕猴桃越易衰老,同时温度波动对猕猴桃品质 的影响也越明显。
英文摘要:
      Temperature fluctuation during refrigerated transport can significantly affect the quality of Kiwi fruits and stor⁃ age process. The kiwi fruits were first placed at different temperature fluctuations 2 ℃(± 0 ℃、± 1.5 ℃、± 3 ℃), and after 24 h refrigerated transportation, were stored at 0 ℃, 3 ℃ and 20 ℃ and then the various parameters of the kiwi fruit were measured such as weight loss rate, fruit firmness, titratable acidity, soluble solids, chlorophyll, MDA, Vitamin C content, etc. It was found that the kiwi fruit quality varied with the different refrigerated time and temperature fluctuations. After 16 days of cold storage, the variation of hardness at ± 3 ℃ was 1.94 times of that at ± 0 ℃, 1.27 times of that at ± 1.5 ℃, when the stored temperature is 0 ℃. Temperature fluctuation accelerated the change of kiwi fruit quality. The greater the tempera⁃ ture fluctuation, the greater the impact on the quality of kiwi fruit. Storage temperature also had a certain impact on it. It was also found that the higher the storage temperature, the much easier the aging of the kiwi fruit, while the influence of temperature fluctuation on the kiwi fruit was also more obvious.
