Effect of fixation methods and various clones of Camellia sinensis var. sinensis (L) properties and antioxidant activity of Indonesian green tea

Fixation is essential in green tea processing to inactivate the polyphenol oxidase enzyme. In Indonesia, made from Assam variety and produced using panning method. Few studies are reported on Indonesian clones of Sinensis variety. This study aims identify chemical characteristics, antioxidant activity, sensory evaluation local (GMBS 2, GMBS 4, 5) with different fixation methods (panning steaming). The results show that caffeine content products ranged 2.51-2.59% 2.67-2.74% for steaming methods. method higher total flavonoid than Green has an IC50 value 14.45; 14.41; 17.41 mg/L 5, respectively. resulted a smaller 2 4 clones. taste, aroma, score those However, did not significantly affect appearance, liquor color, leaf infusion. conclusion, GMB 5 met National Standard 3945:2016.
