不同套袋材料对“三月白”枇杷果实品质的影响

Effects of different bagging materials on fruit quality of Sanyuebai loquat

为了探究不同套袋材料对“三月白”白肉枇杷果实品质的影响,采用双层黄色牛皮纸果袋、单层黄色牛皮纸果袋、外牛皮纸内编织袋双层果袋、单层编织果袋、外黄内黑双层牛皮纸果袋和外黄内黑单层牛皮纸果袋等6种市售果袋套袋,以不套袋做对照,测定不同套袋处理枇杷果实感官、外观和内在品质指标,同时利用主成分分析法筛选最适合的果袋材料。结果表明,6种套袋处理均能不同程度提高“三月白”枇杷的商品果率、单果质量和可食率,但降低了果实的可溶性固形物含量和固酸比;主成分分析综合评价,外层牛皮纸内层编织袋双层袋处理综合得分最高,优于其他套袋处理,建议“三月白”枇杷种植中可优先使用。

In order to investigate the influence of different bagging materials on the fruit quality of Sanyuebai,a white-flesh loquat new strain,six commercial bagging materials including double-layered yellow kraft paper bag,single layer yellow kraft paper bag,double-layered bag with kraft paper outer layer and woven inner layer,single layer woven bag,double-layered bag with outer yellow kraft paper and inner black kraft paper,and single layer outer yellow and inner black kraft paper bag were used to bag the fruit of Sanyuebai,with non-bagging as control.The sensory,external appearance,and internal quality parameters of the loquat fruits were determined and the most suitable fruit bagging material was identified by principal component analysis.The results showed that all six bagging materials increased the commercial fruit rate,single fruit weight,and edible rate of Sanyuebai loquats,but reduced the soluble solid content and sugar-acid ratio of the fruit.Through principal component analysis and comprehensive evaluation,the comprehensive score of the fruits bagged with double-layer bag of outer kraft paper and inner woven was the highest,better than that of other bagging materials.It could be used preferentially for bagging the Sanyuebai loquat fruits.
