decaffeinated tea
The decaffeinated tea, generally called Decaf, is the tea that has removed caffeine. The decaffeinated tea is different from natural herbal teas without caffeine. The decafination is imperfect; Although most of the caffeine is eliminated, some remains (typically around 1-2%, sometimes more). In Ratetea, we denote decaffeinated teas, while herbal teas without natural caffeine are labeled as cf.
The decaffeinated tea usually suffers from lower flavor. People looking for tea drinks without caffeine, but dissatisfied with the quality of decaffeinated tea, can consider exploring rooibos or any other herbal number without caffeine. It is also worth considering, often decafinated, taste teas are often more pleasant than decaffeinated pure teas, because tea can be mixed with flavorings or other ingredients after the decafination process has been carried out, leaving the flavors Additional intact.
Different methods of decapanization.
The decapanization can be carried out by several different processes; Some are safer than others, and they also have different impacts on the flavor.
Ethyl acetate molecule
Ethyl acetate molecule
CO2: This method involves the use of carbon dioxide that has been compressed in a supercritical fluid. This method has the advantage that the only solvent used is carbon dioxide, which is completely non-toxic. CO2 is good for preserving the flavor; Its main drawback is that it is expensive.
Ethyl acetate: Ethyl acetate is an organic solvent commonly used in decafination. It is naturally occurred, both in fruit and tea leaves, and has a low toxicity. Ethyl acetate tends to eliminate more tea flavor than other decaffeination processes; It is mainly used due to its low cost. (2)
Methylene chloride molecule
Methylene chloride molecule
Methylene chloride: Another process of decafination involves methylene chloride, a chlorohydrocarbide, also known as dichloromethane. This process leaves small traces of the chemical inside the decaffeinated tea leaves. The methylene chloride is toxic, and it has been shown to be carcinogenic in animals. This method is legal in the United States, but regulated by the FDA. Companies that sell tea that has been D.
