基于品质分析的EBF樱桃果实采收时期研究

Harvesting standard of EBF cherry fruits based on quality analysis

为确定樱桃果实适时的采收时期,本文以EBF樱桃果实4种采收时期为研究对象,测定了各个时期果实的5项品质指标。结果显示,7成熟(黄色)果的硬度和明度最高,10成熟(深红色)果的最低;8成熟(粉色)果的红绿饱和度(a*)最高,10成熟(深红色)果的最低;10成熟(深红色)果的可溶性蛋白、可溶性糖及Vc含量最高,8成熟(粉色)果的最低。隶属函数综合分析得出,7成熟(黄色)果的品质最好,10成熟(深红色)果次之,9成熟(红色)果与8成熟(粉色)果较差。因此,7成熟(黄色)果是EBF樱桃果实长期贮藏的主要采收时期,9成熟(红色)果是EBF樱桃果实短期贮藏和鲜食的主要采收时期。

In order to determine the timely harvesting period of cherry fruits,the EBF cherry fruits of 4 harvesting periods were regarded as the research objects,and five quality indicators of the EBF cherry fruits in each period were analyzed.The results showed that the hardness and brightness of the fruit with 70%maturity(yellow)was the highest;the fruit with 100%maturity(dark red)was the lowest one;the red-green saturation(a*)of fruit with 80%maturity(pink)was the highest;the fruit with 100%maturity(dark red)had the lowest one;the soluble protein,soluble sugar and Vc of the fruit with 100%maturity(dark red)was the highest,and the fruit with 80%maturity(pink)had the lowest one.According to comprehensive analysis of the index membership function,the quality of the fruit with 70%maturity(yellow)were the best;the second was the fruit with 100%maturity(dark red);the fruit with 90%maturity(red)and the fruit with 80%maturity(pink)were a little bad.Therefore,the fruit with 70%maturity(yellow)was rated as the main harvesting period for long-term storage of EBF cherry fruit;the fruit with 90%maturity(red)was regarded as the main harvesting period for short-term storage and fresh food of EBF cherry fruit.
