Abstract
Kulen je tradicionalni mesni proizvod s područja istočne Hrvatske koji se ubraja u fermentirane trajne kobasice. Tijekom procesiranja fermentiranih proizvoda odvijaju se brojne enzimske i neenzimske reakcije koje dovode do povećanja koncentracije hlapivih komponenata arome. Te komponente su odgovorne za specifične okusne i mirisne osobine ovog proizvoda koje su najzaslužnije za percepciju kvalitete kod potrošača. Za ekstrakciju tih spojeva iz uzoraka korištena je mikroekstrakcija na čvrstoj fazi iz para iznad otopine. Plinsko-kromatografsko-masenom spektometrijskom analizom uzoraka identificirana su 104 hlapiva spoja arome. Identificirani spojevi su pripadali sljedećim kemijskim grupama: terpenima, aldehidima, organosumpornim spojevima, ketonima, aromatskim ugljikovodicima, kiselinama, esterima i laktonima, furanima, benzofuranima i pirazinima, alkoholima, terpenima i alkanima i alkenima. Fenoli, aldehidi, ketoni i organosumporni spojevi su najzastupljeniji spojevi u kulenu. Analizom glavnih komponenata pokazano je da je viša koncentracija alkohola, organosumpornih spojeva i u manjoj mjeri furana, benzofurana i pirazina karakteristična za sve senzorski najlošije ocijenjene uzorke.
Abstract (english)
Kulen is traditional meat product from eastern Croatia and it is considered to be fermented sausage. During the processing of dry-cured meat products numerous enzymatic and nonenzymatic reactions are carried out which leads to an increase of concentration of volatile aroma compounds. These compounds are responsible for the specific olfactory and gustatory properties of the products. This properties have the highest influence on the consumer perception of quality. For extraction of these compounds from the samples headspace solid-phase microextraction was used. With gas chromatography-mass spectrometry analysis of the samples 104 volatile aroma compounds were identified. They belong to the following chemical groups: terpenes, aldehydes, organosulphur compounds, ketones, aromatic hydrocarbons, acids, esters and lactones, furans, benzofurans and pyrazines, alcohols, terpenes, alkanes and alkenes. Phenols, aldehydes, ketones and organosulphur compounds are the most common compounds in kulen. Principal component analysis showed that the higher concentration of alcohol, organosulphur compounds and furan, benzofuran and pyrazine was characteristic for all worst sensory rated samples.
