Safran, Crocus sativus L.
çiçeklerinin kurutulmuş stigmalarından elde edilen, gıda renklendirici ve
lezzet verici olarak yaygın biçimde kullanılan bir baharattır. Bu çalışmanın
amacı, farklı kalite sınıflarına ait safranın krosin içeriğini ve uçucu
bileşenlerini belirlemektir. Safran örneklerinin kalite sınıfları, içerdikleri
kırmızı stigmalar (Sargol-I ve Sargol-II) ve sarı stiluslar (Pushal-I,
Pushal-II ve Bunch) bakımından farklılık göstermektedir. HPLC ile belirlenen
toplam Krosin miktarı Sargol-I örneğinde en yüksek (66.67 mg / g) ve Bunch
örneğinde en düşük (51.66 mg / g) olarak tespit edilmiştir. Safranın uçucu
bileşenleri; GC-MS kullanılarak SPME yöntemi ile belirlenmiş, çalışmada 3
farklı fiber (PA, PDMS ve CAR / PDMS) kullanılarak 40 uçucu bileşik tespit
edilmiştir. Safranın ana uçucu bileşiği olan Safranal; Sargol-I, Sargol-II,
Pushal-I, Pushal-II ve Bunch kategori örneklerinde sırasıyla % 49.64, % 50.29,
% 50.42, % 57.02 ve % 61.31 olarak tespit edilmiştir.

DETERMINATION OF CROCIN CONTENT AND VOLATILE COMPONENTS IN DIFFERENT QUALITIES OF IRANIAN SAFFRON

Öz

Saffron, obtained from dried
stigmas of Crocus sativus L. flowers, is widely used as a food colouring
and flavouring spice. The aim of this study was to determine crocin content and
volatile constituents of saffron belonging to different quality categories. The
quality categories of saffron samples differ in red stigmas (Sargol-I and
Sargol-II) and threads with yellow styles (Pushal-I, Pushal-II and Bunch). The
total amount of the crocin component was identified with HPLC as highest in the
Sargol-I sample (66.67 mg/g) and lowest in the Bunch sample (51.66 mg/g). SPME
followed by GC-MS was used to screen of saffron volatile composition. As the
result of study, 40 volatile compounds were detected by 3 different fibers (PA,
PDMS and CAR/PDMS). GC-MS (PDMS). Safranal, the main volatile compound of
saffron, was determined in the Sargol-I, Sargol-II, Pushal-I, Pushal-II and
Bunch category samples as 49.64%, 50.29%, 50.42%, 57.02% and 61.31%,
respectively.
