How Much Caffeine is in Edible Green® Sencha Powder and Matcha Green Tea Powder?

Green Tea, Oolong Tea, and Black Tea are produced from the leaves of Camellia Sinensis, which contains caffeine naturally. The fermentation and finishing process make the unique flavor and nutrition in each type of tea. Green Tea is not fermented at all. Oolong tea is half farmented.  Black Tea is nearly completely fermented. This fermentation process, or oxidation process, changes the natural substances in tea leaves, such as Caffeine and Catechins. “Catechins” are the most prominent antioxidants and the reason Green Tea has been in the center of scientists’ attention.  Green tea leaves contains the highest amount of Catechins, because farmentation process decreases Catechins in the tea leaves.

Caffeine and Catechins (EGCG) relationship in tea leaves

Oxidation decreases Catechins and EGCG in tea leaf.  There are two ways to stop oxidation after tea leaf is harvested:  Steam or Panning.  Both methods kill the enzyme causing oxidation in tea leaf.  Scientific tests show tea steaming method offers higher Catechin & EGCG amount than panning method.

Typically, Japanese green tea uses steaming method, and Chinese green tea uses panning method.

* Edible Green® regular is Japanaese Sencha green tea powder.  One serving of Edible Green®, 1/4 tsp. powder, contains about the same amount as in 1 bar of Hershey Chocolate bar (1.55oz), which contains 9 mg of Caffeine. Edible Green® regular offers about 1/10 of caffeine in regular coffee and offers much more Catechins than brewed green tea.

** Edible Green® decaffeinated still contains 95% of the EGCG antioxidants.

*** Matcha also contains high dose of L-theanine naturally.  L-theanine is a natural relaxant that calms nervous system and increases alpha waves in brain without causing drowsiness.    A great balance of Caffeine and L-theanine creates “calm alertness” and provides steady energy.  Read about:
