Decaffeinated Tea – The four ways to Decaffeinate

Decaffeinated Tea - Black

Decaffeinated Tea is really nice for tea lovers, who want to avoid caffeine. The most popular forms of tea i.e. black tea and green tea can be decaffeinated. The process of decaffeination though leaves a little caffeine in the leaves. There are four methods to get decaffeinated tea.

Methylene Chloride treatment – The tea leaves are soaked in water with traces of Methylene Chloride. Methylene Chloride removes caffeine by bonding with the molecules. However this chemical is not deemed to be healthy and its use in decaffeination has been mostly discontinued.

• Natural Decaffeination – Processing the tea leaves with ethyl acetate is termed as natural decaffeination. The reason for the nomenclature is because ethyl acetate is naturally found in tea. However most of the tea is not decaffeinated this way, as it is almost impossible to remove the chemical.

• Carbon Dioxide treatment – Cooking with high pressured Carbon Dioxide is the best process for decaffeination. The gas removes the caffeine from leaves at molecular level, keeping the natural flavour intact. This method is also known as organic decaffeination.

• The coffee method – Using water extraction is a common method for coffee decaffeination. Some amounts of tea decaffeination uses this method, where the leaves are soaked in hot water and then passed through carbon filter to remove caffeine.
