Abstract

The aim of this study was to determine and classify commercial red wines of domestic and foreign varieties harvested from different geographical regions using electronic nose and chemometrics according to their aroma profiles. Aroma profiles of 21 wine samples were analyzed by the zNoseTM instrument. Principal component analysis PCA and cluster analysis CA were used for the classification of wines on the basis of their aroma profiles. According to PCA and CA results, wines produced from same grape varieties and harvested from closer regions classified in the same groups based on their aromas

Farklı Bölgelere Ait Ticari Kırmızı Şarapların Elektronik Burun ile Aroma Profillerine Göre Sınıflandırılması

Abstract

Çalışmada ülkemizde yetişen yerli ve yabancı üzüm çeşitlerinden elde edilmiş ticari kırmızı şarapların aroma profilleri elektronik burun ile belirlenmiş ve kemometrik yöntemlerle sınıflandırılmıştır. Araştırmada 21 adet ticari şarap kullanılmış olup aroma profilleri zNoseTM cihazı ile belirlenmiştir. Temel bileşen analizi PCA ve kümeleme analizi CA kullanılarak şarapların aroma profillerine göre sınıflandırılması yapılmıştır. PCA ve CA analiz sonuçlarına göre yakın bölgelerden sağlanan aynı üzüm çeşidinden üretilen şaraplar aromalarına göre yakın gruplandırılmışlardır
