Analysis of caffeine
The team at CAMELLIA SINENSIS Teahouse in collaboration with the College Centre for the Transfer of Technologies TransBIOTech, conducted a series of studies on the levels of antioxidants and caffeine in different teas. The analyses were conducted so that the results reflect what the tea drinker gets from their cup, in the context of daily consumption. Each year we select around ten teas, of different styles and pricing, to add new results to this table.
CAFFEINE CONCENTRATION OF VARIOUS TEA INFUSIONS (DETERMINATION OF CAFFEINE BY LIQUID CHROMATOGRAPHY – UV)
All teas were weighed at 5g and brewed in a teapot, in 500 ml of water, except for the Matchas, which has been whipped in a bowl containing 1.5g of tea for 100 ml of water. It is important to note that for the Matcha, the concentration of tea compared to the amount of water is higher than other teas because we chose to measure levels of caffeine in relation to how the tea is normally consumed.
