35份云南小粒种咖啡生豆品质综合评价
Comprehensive Evaluation on the Green Bean Quality of 35 Materials of Coffea arabica from Yunnan
摘要
Abstract
Taking 35 green beans of Coffea arabica from 3 main production areas of Lincang,Baoshan and Dehong in Yunnan Province as the research materials,15 chemical characteristic indicators such as moisture content,ash content,potassium,calcium,magnesium,copper,zinc,iron,manganese,phosphorus,crude fiber,crude fat,protein,caffeine and chlorogenic acid were determined.Descrip-tive statistics,ANOVA analysis of variance,correlation analysis and entropy method were used to conduct a systematic evaluation of green beans of Coffea arabica.The results indicated that at 14 in-dicators,there was weak variation to moderate variation,and only the manganese genus was highly variable,with the number of variant strains reaching 95.67％.The results of ANOVA variance analy-sis indicated that there were significant differences in seven indicators such as copper,zinc,manga-nese,protein,crude fiber,crude fat,and caffeine among the Coffea arabica beans of the 3 prefec-tures(cities).The key flavor precursors of protein and caffeine could be used as characteristic indica-tors of Dehong coffea.Manganese and crude fat could be used as characteristic indicators of Coffea arabica in Lincang.Copper,zinc and crude fiber could be used as characteristic indicators of Coffea arabica in Baoshan.The results of the correlation analysis showed that there were varying degrees of correlation among the 15 indicators of Coffea arabica beans.The analysis results of the entropy method showed that the top 10 varieties involved in the comprehensive score were Dere No.6,400,PR107,Dere No.5,585,296,Cartimor,and Ruiken 48-1.8 high-quality Coffea arabica germplasm resources through comprehensive evaluation were screened out.关键词
