avs :donor:<p>I only use Ceylon <a href="https://infosec.exchange/tags/cinnamon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cinnamon</span></a> (C. verum) because I try to avoid <a href="https://infosec.exchange/tags/coumarin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coumarin</span></a>, which is poisonous. (You should, too.) In order to authenticate the cinnamon I buy, I am experimenting with ways to detect coumarin at home. This sample is C. burmannii and the fluorescence you see here should be coumarin. In addition, my C. cassia and an el cheapo cinnamon of unknown type (I presume cassia) showed this. My two C. verum samples had nothing.<br>My attempt was to get the coumarin out with methanol (or I guess you can use cheap moonshine), and drip it on NaOH (drain opener) soaked <a href="https://infosec.exchange/tags/Aeropress" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Aeropress</span></a> filters, then dry and illuminate with UV. Am I right here? Anyone? <a href="https://infosec.exchange/tags/homelab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>homelab</span></a> <a href="https://infosec.exchange/tags/chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>chemistry</span></a></p>
