Multi-indicator Quality Evaluation of Three Ginger Based on Amino Acids and Trace Elements
Three types of ginger from different origins,namely Sishui County of Jining,Shandong Province,Heng County of Nanning,Guangxi,and Rong County of Zigong,Sichuan Province,were selected as the research objects to determine the calorific value,combustion stability,fat,crude fibre,ash,trace elements and amino acids of the three types of ginger.The results showed that the combustion heat content of the three types of ginger ranged from 17 813.06～19 878.53 J/g,with an average value of 18 707.66 J/g,and the size ranking was Nanning Hengxian,Guangxi＞Zigong Rongxian,Sichuan＞Sishui County,Jining,Shandong;the combustion stability values of the three types of ginger were 0.474 20,0.262 86 and 0.425 42,respectively,and the combustion stability was ranked as Shandong Jining Sishui County＞Sichuan Zigong Rongxian＞Guangxi Nanning Hengxian;the fat content was in the range of 1.71％～2.32％,with an average value of 2.02％,and the order was Guangxi Nanning Hengxian＞Shandong Jining Sishui County＞Sichuan Zigong Rongxian;the ash content ranged from 6.82％to 11.54％,with an average value of 9.22％,and the order was Shandong Jining Sishui County＞Sichuan Zigong Rong County＞Guangxi Nanning Heng County;the crude fibre content ranged from 8.88％to 12.34％,with an average value of 11.08％,and the size order was Rongxian,Zigong,Sichuan＞Sishui County,Jining,Shandong＞Hengxian,Nanning,Guangxi;the comprehensive evaluation values of the three types of ginger were-0.159 7,0.780 5 and-0.620 9,and the size order was Hengxian,Nanning,Guangxi＞Sishui,Jining,Shandong＞Rongxian,Zigong,Sichuan.This study establishes a multi-indicator analysis and evaluation system for three types of ginger,which will provide a solid scientific basis for large-scale ginger resource development and ginger classification research.
