If you’ve ever been curious about decaf tea, you’re not alone. Decaf teas have lately become more popular, and for a good reason. They may provide comparable health benefits as ordinary teas while avoiding the caffeine side effects. Read our article on deaf teas to learn more.
What is decaffeinated tea?
Although many tea drinkers avoid drinking tea only because of caffeine, the discussion about whether or not to consume coffee is still very prevalent. According to UK Loose Leaf Tea, a cup of tea has between 20 and 100 milligrams of caffeine, on average. The amount of caffeine in a cup of tea is determined by a variety of factors, although you may influence some of them. Steeping fewer tea leaves in cooler water for a shorter period of time will result in a cup that has less caffeine but an inferior taste. You can’t get rid of the caffeine by washing tea leaves with hot water before brewing a cup.
The most frequent ways to decaffeinate tea are as follows:
1. Using solvents directly
The caffeine and other components are removed in a similar way, using direct solvents such as ethyl acetate or methylene chloride. The leaves are steamed and soaked in a solvent to remove the majority of the caffeine. This is one of the oldest decaffeination processes, which was invented more than 100 years ago.
2. CO2 method
The CO2 or Supercritical Carbon Dioxide technique is now widely regarded as the most acceptable approach for decaffeinating teas. It preserves almost all nutrients while removing caffeine, unlike other techniques. When tea is brewed by boiling, the flavouring and health benefits are preserved nearly intact. Only 5% of the nutritional value is lost. Tea leaves are soaked in water or alcohol and then subjected to high-pressure processing using CO2 as a solvent.
What’s the difference between caffeinated and decaf teas?
Caffeinated and decaf teas, while similar in taste, may have minor distinctions. Smaller broken leaves are present in the majority of decaf teas. Decaffeination methods and tea types will influence the flavour of decaf teas. Many of the flavours and advantages will be kept, thus giving you a cup that isn’t very distinct from caffeinated tea. The amount of caffeine will be drastically reduced, but there will still be some left, generally less than 2 mg per cup, although some types may have more – even 5 mg per cup.
It’s fascinating to note that, by and large, decaf teas are still black. Even if CO2 is used to decaffeinate green tea, the amount of EGCg may be reduced by up to 37.8%. However, this will also be determined by the solvent used in the decaffeination technique. When water was used as a solvent, it lost more catechins than ethanol, which decreased the catechin content by only 6.2%, according to study results.
Decaf teas, like regular teas, should be prepared in the same manner, using boiling water for black tea and cooler water for green tea.
Caffeine-free tea Vs Decaffeinated
Decaffeinated tea is simply defined as all tea that was originally composed of caffeine but has subsequently been removed through a decaffeination process. All teas that are naturally caffeine-free are known as decaffeinated teas. Peppermint, ginger, rooibos or chamomile tea are all herbal teas that can help with indigestion. Decaffeinated teas are prepared from Camellia sinensis tea which is naturally high in caffeine. All caffeine-free teas will be 0% caffeine, although decaf teas may have trace amounts (but usually less than 2 mg per cup).
