基于氨基酸和微量元素3种生姜多指标品质评价

Multi-indicator Quality Evaluation of Three Ginger Based on Amino Acids and Trace Elements

选择山东济宁泗水县、广西南宁横县、四川自贡荣县三种不同产地的生姜作为研究对象,测定三种生姜的燃烧热、燃烧稳定性、脂肪、粗纤维、灰分、微量元素、氨基酸。结果表明,3种生姜燃烧热含量在17813.06~19878.53 J/g,平均值为18707.66 J/g,大小排序为广西南宁横县>四川自贡荣县>山东济宁泗水县;3种生姜稳定性值分别为0.47420,0.26286,0.42542,燃烧稳定性排序为山东济宁泗水县>四川自贡荣县>广西南宁横县;脂肪含量在1.71%~2.32%,平均值为2.02%,大小顺序为广西南宁横县>山东济宁泗水县>四川自贡荣县。灰分含量在6.82%~11.54%,平均值为9.22%,大小顺序为山东济宁泗水县>四川自贡荣县>广西南宁横县。粗纤维含量在8.88%~12.34%,平均值为11.08%,大小顺序为四川自贡荣县>山东济宁泗水县>广西南宁横县;3种生姜综合评价值为-0.1597,0.7805,-0.6209,大小顺序为广西南宁横县>山东济宁泗水县>四川自贡荣县。本研究建立3种生姜的多指标分析及评价体系,为大规模开发生姜资源以及生姜分类研究提供有力的科学依据。

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 17813.06~19878.53 J/g,with an average value of 18707.66 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 0.47420,0.26286 and 0.42542,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-0.1597,0.7805 and-0.6209,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.
