Traditions and green tea go hand in hand. Green tea is steeped (pun intended) in ritual and history through centuries of consumption. The idea that tea connoisseurs have perfected the best brewed green tea is not a difficult concept to embrace. It isn’t surprising that there has been a lot of research done on green tea.
After centuries of green tea, you would think everything that needs to be known is known about this most beneficial drink. After all, science has determined that green tea is one of the most beneficial beverages available for consumption. Its health benefits are numerous.
I respect science and its research, after all it is one of the things that has made our product outstanding in the market. Always with an open mind, we journeyed into the unknown with this question, “Is using the microwave good for green tea?”
In pursuit of the definitive answer between the purist versus the scientist, even we were surprised at the findings on this one. Several studies have uncovered a very interesting side effect of processing green tea with the use of the microwave.
Those results follow.
In 2012, Dr. Quan Vuong, from the University of Newcastle, Australia, conducted a study on the consequences of brewing green tea through microwave extractions; specifically how the compounds within the tea leaves were affected.
Based on his documented analysis, Dr. Vuong’s research resolved that microwaving green tea extracted more beneficial nutrients and caffeine versus other extraction methods, like conventional heating and ultrasound extraction.
In the first study, microwaved extraction of one minute with 400 W microwave was used to completely extract the catechin and epicatechin from green tea. Comparatively, ultrasonic extraction required 60 minutes to extract the catechin and epicatechin from green tea.
In a second study, microwaved heating at low wattage and conventional kettle heating maintained green tea heated at 175 degree F (80 degree C) for 30 minutes.
The study revealed that the microwaved green tea had a higher level of catechins than conventional heating. The study states, “[M]icrowave-assisted water extraction (MWE) . . . appears more efficient than CWE (conventional water extraction) at both 80- and 100-degrees C, particularly for the extraction of flavanols and hydroxycinnamic acids.”
In a third study, microwaving green tea destroys polyphenol oxidase. Polyphenol oxidase is an enzyme that degrades polyphenol. When this enzyme is destroyed, as it is during microwaving, the extraction leads to a higher level of catechins and phenols. The result is a sweeter, tastier, more colorful, and higher quality green tea brew.
The tests also reveal that brewing green tea by microwave, you can extract approximately 80% of the catechins and 92% of the caffeine.
Microwaving versus conventional heating, produces a higher extraction and protection of catechins (powerful polyphenol anti-oxidant)
Microwaving versus conventional heating, produces a higher extraction and protection of epicatechin (powerful anti-oxidant flavonoid)
Microwaving versus conventional heating, produces a higher extraction and protection of flavanol epigallocatechin gallate
Microwaving versus conventional heating, produces a higher extraction and protection of hydroxycinnamic acids
Microwaving extracts approximately 92% of caffeine level in green tea
Following the research steps above we offer a new recipe option for brewing green tea:
Place Japanese sencha green tea into a microwave-safe cup and add cold filtered water;
Heat at 400W to 500W microwave power for approximately 1 minute;
Steep heated beverage for approximately 1 to 2 minutes;
Remove tea leaf residue;
Add condiments to taste.
Scientific research has spoken and revealed that it is perfectly safe to microwave your Japanese green tea. So, if you’re in a rush, rest assured, crank up the microwave, and enjoy the healthiest beverage through the scientifically promoted healthiest process.
Just remember, there is a spiritual health that comes from tradition and ritual. So, if you’re a purist and have the time, may you enjoy your green tea ritual of Chanoyu, the beautiful ceremonial preparation and presentation of green tea matcha.
