摘要
为了解南瓜贮藏期维生素C含量、果胶含量、可溶性固形物含量等果实品质的变化规律,以百蜜3号和百蜜5号南瓜为试验材料,对南瓜果实采后10~60 d内的生理指标进行动态测定,以期为南瓜果实食用期的选择和原料加工利用提供理论依据。结果表明,随着贮藏时间的延长,2个品种的维生素C含量、果胶含量呈下降趋势,可溶性固形物含量呈先下降后上升再下降趋势,失重率呈上升趋势。2个品种的维生素C含量与果胶含量、失重率与丙二醛含量呈极显著正相关。在采后贮藏40 d内可溶性固形物含量相对较高,丙二醛含量积累较少,果实品质处于较好的状态。
In order to understand the changes of soluble sugar contect,pectin contect,starch contect and other fruit quality during the storage period of pumpkin,the physiological indexes of pumpkin fruits were dynamically determined from 10 to 60 d after harvesting,using BaiMi 3 and BaiMi 5 pumpkins as experimental materials,in order to provide a theoretical basis for the selection of the consumption period of pumpkin fruits and the processing and utilization of raw materials.The results showed that with the extension of storage time,the contents of vitamin C,pectin in both varieties decreased continuously,the contents of soluble solids decreased first and then increased and afterward decreased,the weight loss rate content increased continuously,Correlation analysis showed that a highly significant positive correlation was found between the contents of vitamin C and pectin,weight loss and the contents of MDA for the two varieties.The contents of soluble solids andβ-carotene were higher within 40 days of postharvest storage,and the accumulation of MDA content was lower,indicating a good condition of the fruit quality.
