\u00cbsht\u00eb e r\u00ebnd\u00ebsishme t\u00eb kuptohet se kimia aromatike e luleve \u00ebsht\u00eb komplekse – thot\u00eb shkencologu i luleve, autori A. Brunning.

Ajo arom\u00eb karakteristike t\u00eb cil\u00ebn e “zbulon” hunda jon\u00eb, n\u00eb shum\u00eb raste do jet\u00eb e shkaktuar nga molekulat q\u00eb e japin kontributin m\u00eb t\u00eb madh aromatik.
\nAroma e tr\u00ebndafilave ndikohet kryesisht nga p\u00ebrb\u00ebrja e quajtur (-)-cis-oksidi<\/strong> i tr\u00ebndafilit. Kjo molekul\u00eb \u00ebsht\u00eb nj\u00eb izomer i ve\u00e7ant\u00eb i oksidit tr\u00ebndafilesk (i cili ka 4 izomer\u00eb t\u00eb ndrysh\u00ebm), dhe ky izomer kontribuon n\u00eb arom\u00ebn tipike t\u00eb tr\u00ebndafilit si lule. Edhe n\u00ebse me sasi shum\u00eb t\u00eb ul\u00ebta n\u00eb aj\u00ebr – aq ul\u00ebt, deri n\u00eb 5 pjes\u00ebzat e miliardit, aroma e tr\u00ebndafilit kapet leht\u00eb nga hunda jon\u00eb. P\u00ebr t’i dh\u00ebn\u00eb k\u00ebsaj nj\u00eb p\u00ebrspektiv\u00eb, 1 pjes\u00ebz molekulare n\u00eb 1 miliard \u00ebsht\u00eb baraz me 1 sekond\u00eb n\u00eb 32 vjet – e ka p\u00ebrdorur si karahasim autori Brunning : )<\/p>\n

Nj\u00eb p\u00ebrb\u00ebr\u00ebs tjet\u00ebr q\u00eb kontribuon n\u00eb arom\u00ebn e tr\u00ebndafilave \u00ebsht\u00eb beta-damascenone<\/strong>.

Gjithashtu si kontribues i r\u00ebnd\u00ebsish\u00ebm, nj\u00eb p\u00ebrb\u00ebr\u00ebs tjet\u00ebr me prag relativisht t\u00eb ul\u00ebt aromatik \u00ebsht\u00eb beta-jononi<\/strong>.
