中文摘要:

      随着社会进步和生活水平的提高, 消费者对农产品的消费需求从“量”转变为“质”, 即从追求“吃得饱”转向“吃得好”, 希望获得优质的农产品。如何评价农产品是否优质成为新时代农业行业的重要任务。农产品品质评价过程包括品质指标的确定和评价方法的选择以及在此基础上建立的评价体系。农产品品质评价指标的确定要根据研究主体的特点, 结合消费偏好、文献调研等进行评价。本文结合文献和工作经验就方差分析、相关性分析、回归分析、聚类分析、因子分析和主成分分析、判别分析等在品质评价过程中如何应用及注意事项做了详细描述。对完善农产品品质评价体系的构建提出了3点建议: 制修订相关评价标准、采用多种科学合理的数理统计方法进行综合评价和基于评价模型开发实用软件, 对农产品统一标准进行评价。最后针对代谢组学技术在农产品品质挖掘方面的应用对农产品品质评价工作提出了展望, 以期为农产品品质评价提供方法和思路的借鉴和参考。

英文摘要:

      With the improvement of social progress and living standards, consumers’ demand for agricultural products has changed from “quantity” to “quality”, that is, from the pursuit of “being full” to “eating well”, hoping to obtain high quality agricultural products. How to evaluate the quality of agricultural products has become an important task of agricultural industry in the new era. The evaluation process of agricultural products quality includes the determination of quality index and the selection of evaluation methods as well as the evaluation system established on this basis. The evaluation index of agricultural products quality should be determined according to the characteristics of the products, combined with consumer preferences and literature research. And this article provided a detailed description of the application and precautions of variance analysis, correlation analysis, regression analysis, cluster analysis, factor analysis, principal component analysis, discriminant analysis, etc. in the quality evaluation process, based on literature and work experience. The 3 suggestions were also gave to improve the construction of the agricultural product quality evaluation system, which are making and revising the relevant evaluation standards, adopting a variety of scientific and reasonable mathematical statistical methods for comprehensive evaluation, and developing practical software based on the evaluation model to evaluate agricultural products with unified standards. Finally, the application of metabolomics technology in agricultural product quality research is prospected for agricultural product quality evaluation, and to provide reference for the methods and ideas of quality evaluation of agricultural products.
