Tea is one of the most widely consumed beverages in the world because of its low price as well as pleasing aroma. The total number of volatiles identified in black tea aroma is now over 470 including alcohols, aldehydes, acids, hydrocarbons, ketones, esters, lactones and others. Aroma compounds are mainly derived from unsaturated fatty acids, carotenoids, amino acids and terpenoids during tea processing. The aroma is the most remarkable parameter determining tea quality and the price of made tea.

Siyah Çayda Aroma Maddelerinin Oluşumu

Öz

Çay hoş aroması ve düşük fiyatından dolayı tüm dünyada en fazla tüketilen içeceklerden birisidir. Siyah çayda tanımlanan alkol, aldehit, asit, hidrokarbon, keton, ester, lakton ve diğer uçucu bileşenlerin sayısı 470'den fazladır. Aroma bileşenleri büyük ölçüde çayın işlenmesi sırasında doymamış yağ asitlerinden, karotenoitlerden, aminoasitlerden ve terpenoitlerden oluşmaktadır. Aroma, çayın kalitesini ve fiyatını belirleyen en önemli parametredir.
