Tea in Sri Lanka with you
Don’t miss Professor of Chemistry, Siromi Samarasinghe this afternoon. Until then I leave you with a little Sting.

Join us for a STEM Women HOA as we speak to Professor Siromi Samarasinghe from the University of Sri Jayawardenapura, Sri Lanka. Siromi lectures in organic chemistry and her research interests include the chemistry of tea compounds. She will talk to us about her research and career path, and also share her experiences of studying abroad and mentoring students.
You can read more about Siromi here: http://www.stemwomen.net/science-helped-me-to-overcome-challenges-in-life/
This HOA will be hosted by Dr Zuleyka Zevallos and Professor Rajini Rao. You can tune in on Sunday 5th October at 1.30 PM Pacific or 9.30PM UK/ Monday 6th 7.30 AM AUS.
The hangout will be available for viewing on our YouTube channel after the event: http://www.youtube.com/stemwomen

I hope Siromi Samarasinghe can settle the argument of milk first, when making tea. Science should settle the argument right?

Thanks for sharing Chad Haney The temperature and the duration of brewing is important to extract all the compounds that contribute to the flavour of tea. What milk proteins do is that they complex with the polyphenols in tea, and perhaps reduce the astringency that we feel on the tongue when a strong cup of tea without milk is tasted. Milk contains casein as the major protein and whey proteins. Casein is stable to heat whereas the whey proteins can get denatured at high temperatures. High temperatures give a ‘cooked taste’ to milk due to the formation of volatile compounds. So adding milk to tea before or after may bring about changes in the taste Therefore it is individual preference.

Thanks Siromi Samarasinghe for explaining the complexity of tea and milk. Have you written about that already? If not, I’m sure a lot of Brits would like to argue, I mean, discuss it with you. I think leaving it as a personal preference is very wise.

Chad Haney I haven’t written about this topic in detail. Thanks for the suggestion.

I look forward to seeing it, if you write about it, Siromi Samarasinghe
