According to the traditional method, for the majority of the growth period, the tea bushes are covered using bamboo mats to shade the leaves from excessive direct sunlight. It is particularly rich in antioxidant compounds as a result of the special cultivation method. The popular beverage has been growing around the world. Matcha is a powdered type of Japanese green tea ( Camellia sinensis) of the Tencha variety. Green tea is available in many variants: in the form of loose leaves, packed into teabags or powdered. Its distinctive flavour, aroma and health-promoting effects are highly valued around the world, as are its socio-cultural connotations. Tea is one of the most consumed beverages, second only to water, in many societies. It is the first such review to be undertaken, and presents its main bioactive compounds in a systematic manner. The aim of this review was to compile the health benefits of matcha tea. Due to its potential for preventing many diseases and supporting cognitive function, regular consumption of matcha may have a positive effect on both physical and mental health. Studies confirming the high antioxidant potential of tea beverages claim that it originates from the considerable content of catechins, a type of phenolic compound with beneficial effects on human health. Its health-promoting properties are attributed to the high content of antioxidant and anti-inflammatory substances. Due to its unique chemical composition and prized flavour, which sets it apart from other tea beverages, it is considered the highest quality tea. Green tea contains four main catechins, i.e., (−)-epicatechin (EC), (−)-epicatechin-3-gallate (ECG), (−)-epigallocatechin (EGC) and (−)-epigallocatechin-3-gallate (EGCG), of which the latter is the most active and abundant and matcha is their best condensed source. Shading of the plants during the growth period enhances the processes of synthesis and accumulation of biologically active compounds, including theanine, caffeine, chlorophyll and various types of catechins. A great balance of Caffeine and L-theanine creates “calm alertness” and provides steady energy.Japanese matcha is a type of powdered green tea, grown in a traditional way.
L-theanine is a natural relaxant that calms nervous system and increases alpha waves in brain without causing drowsiness. *** Matcha also contains high dose of L-theanine naturally. ** Edible Green® decaffeinated still contains 95% of the EGCG antioxidants. Edible Green® regular offers about 1/10 of caffeine in regular coffee and offers much more Catechins than brewed green tea. 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 is Japanaese Sencha green tea powder. Source: Caffeine amounts in other products are taking from. Caffeine in Green TeaĬaffeine amount in 8 oz of tea and coffee: Edible Green®, regular * Typically, Japanese green tea uses steaming method, and Chinese green tea uses panning method. Scientific tests show tea steaming method offers higher Catechin & EGCG amount than panning method. Both methods kill the enzyme causing oxidation in tea leaf. There are two ways to stop oxidation after tea leaf is harvested: Steam or Panning. Oxidation decreases Catechins and EGCG in tea leaf. Caffeine and Catechins (EGCG) relationship in tea leaves
Green tea leaves contains the highest amount of Catechins, because farmentation process decreases Catechins in the tea leaves. 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. Black Tea is nearly completely fermented. 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.
