Quality Analysis of Shuangfeng Mountain Tea and Production Path of Product Quality Standardization:A Case Study of Green Tea in Xiaogan City
In this study,wild alpine tea and artificial tea in Shuangfeng Mountain area of Xiaogan City were selected as the research objects.The quality of tea was analyzed by sensory evaluation and the determination of ef-fective components and harmful substances of tea.The results showed that alpine wild tea was flat and smooth in appearance,dark green and moist in color,bright in soup color,fragrant in aroma,fresher and fresher in taste with a green and astringent taste and the leaf base was tender and even.The sensory evaluation score was 89.00.The active components of alpine wild tea are as the following.The content of water extract was 50.2%,the content of tea polyphenols was 21.5%and the content of caffeine was 3.4%.The content of water extract,tea polyphenols and caffeine was basically the same as that of artificial tea.The content of free amino acid and soluble total sugar were 4.2%and 8.27%respectively,the phenol-ammonia ratio was 5.11 and the content of theanine was 1.54%.The contents of free amino acids and theanine were higher than those of artificial tea and the ratio of phenol to ammonia was lower than that of artificial tea.The contents of harmful substances in wild green tea were all lower than the national standard range,and the contents of chromium,cadmium and fluoride were less than those in arti-ficial tea and no arsenic and tin were detected.On the whole,Shuangfeng Mountain tea's overall quality is good,alpine wild tea pollution is low with specific product characteristics and advantages.The rural cooperative mode cannot ensure the stability of farmers'tea income and is not suitable for market operation.Provincial and municipal scientific research institutions can optimize and improve tea tree varieties and manual roasting steps,further improve product quality,introduce standardized production of local tea enterprises,ensure stable product sales,control quality and achieve a win-win situation in all aspects.
