基于主成分分析对不同地区辣椒品质的综合评价

Comprehensive Evaluation of Peppers Quality from Different Regions based on Principal Component Analysis

  • 摘要: 为探究朝天椒在不同地区品质的差异,选择三个朝天椒品种(骄阳6号、辣研101和卓椒新52)在贵州、云南、重庆、陕西和新疆进行种植。通过研究种植于不同地区朝天椒辣椒红素、还原糖、氨基酸、粗纤维、粗脂肪、辣椒素等营养品质的变化,采用主成分分析和聚类分析分析不同品种朝天椒的产地适宜性,以期为不同地区朝天椒的选择提供借鉴。结果表明:辣椒品质产地变异较大,范围从5.79%~50.29%,其中辣椒素含量随产地的变化最大,平均变异系数达到41.94%,粗纤维和氨基酸平均变异系数在8%左右。通过主成分分析得到,贵州辣研101的综合得分最高,其次为贵州的卓椒新52,三个品种均表现出在贵州种植的品质得分高于其他四个地区。综上所述,辣椒品种在不同的产地种植其品质会有显著差异,三个品种均表现出在贵州地区种植的品质优势,其中,贵州辣研101综合得分最高。

     

    Abstract: To investigate the variation in pepper quality across different regions, we selected three pepper varieties (Jiao yang 6, La yan 101 and Zhuo jiao xin 52) and planted them in Guizhou, Yunnan, Chongqing, Shaanxi and Xinjian Provinces. In order to provide reference for the selection of pepper varieties in different regions, principal component analysis and cluster analysis were employed to evaluate the suitability of each pepper variety for its region by determining the peppers nutritional quality, such as capsaicin, reducing sugar, amino acids, crude fibre, crude fat, capsaicin. The study revealed that significant variations presented in pepper quality across different producing areas and the coefficient of variation ranged from 5.79% to 50.29%. Notably, the average coefficient of variation was 41.94% for capsaicin and was about 8% for crude fiber and amino acids. We found that the comprehensive evaluation of La yan 101 variety was the highest, then Zhuo jiao xin 52 was the second by principal component analysis. Meanwhile, all three varieties showed higher quality scores when planted in Guizhou Province compared to other four regions. In summary, peppers quality varied significantly among different regions and La yan 101 planted in Guizhou demonstrated the best quality performance. Thus we concluded that these peppers planted in Guizhou Province had quality advantages to other four provinces.
