Would you like a spot of tea … microwaved? Nuking a meal in the microwave is usually not considered to be the best way to enhance flavor or preserve nutrients in food preparation. So, who could have guessed that heating tea in a microwave actually has some benefits?
In 2012, food scientist Quan Vuong, PhD from the School of Environmental Science at the University of Newcastle on the Central Coast of New South Wales in Australia looked into how black and green teas are improved by being zapped in the microwave. His study recently resurfaced when a brewing debate emerged after an episode of the British television drama Broadchurch. In the show, David Tennant’s character prepared his tea in a microwave.
“How possibly could microwaving a cup of tea be more beneficial than pouring boiling water from a tea kettle over a tea bag?” many asked. According to Vuong, a microwave can “extract, isolate and purify the important components,” reported ABC Australia. Apparently, Vuong’s research revealed that microwaving a cup of tea enhances its flavor by activating the majority of the polyphenol theanine and caffeine compounds, reports the Mirror. These bioactive compounds produce the flavor in tea that we know and love.
Furthermore, Vuong’s research shows that a microwave extracts these components from tea leaves better than traditional preparations. Steeping a tea bag in hot water for about 30 seconds extracts only 10 percent of the tea’s benefits, reports the Huffington Post. However, heating tea in a microwave for 30 seconds extracts 80 percent of the tea’s good components. Results are comparable for both black and green teas. Extracting all of the beneficial compounds from tea with the traditional steeping method, takes 20 minutes.
Per ABC Australia, Vuong’s method is:
- Put hot water in the cup with your tea bag.
- Heat the microwave for 30 seconds on half power.
- Let it sit for a minute.
