Formula: C6H8N2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2-Ethylpyrazine, is researched, Molecular C6H8N2, CAS is 13925-00-3, about Characterization of Key Odorants in Moroccan Argan Oil by Aroma Extract Dilution Analysis.

The aroma-active compounds of Moroccan argan oil are sensorily and instrumentally analyzed via gas chromatog.-mass spectrometry-olfactometry (GC-MS-O). The purge and trap extraction (PTE) method is used for the extraction of volatile components. A total of 35 aroma compounds are determined including mostly alcs. and pyrazines, and some carboxylic acids, pyrroles, furans, lactones, volatile phenols, an aldehyde, and a ketone. An aroma extract dilution anal. of the aromatic fraction of argan oil isolated by the PTE method reveals 19 key odorants with flavor dilution (FD) factors ranging from 4 to 512, among which nonanal, 2,5-dimethyl-3-ethylpyrazine and 2,3-diethyl-5-methylpyrazine show the highest FD factors of 512. As for the principal scents perceived by all panelists, characteristic odor notes in argan oil are found to be roasty, nutty, fatty, earthy, and cheesy. Practical Applications: Nut oil is one of the most widely consumed oils in many countries. The outcomes of this investigation provide valuable information for elucidation of the key odorants and aroma composition of the well-known and expensive Moroccan argan oil. Aroma is a crucial quality parameter of a foodstuff which directly influences customer preferences. Therefore, determining the key odorants of argan oil’s aromatic extract isolated by purge and trap methodol. is of major importance for the argan oil sector. The purge and trap extraction set for separation followed by anal. and characterization of those compounds via gas chromatog.-mass spectrometry-olfactometry (GC-MS-O) is an effective practical application tool for aroma description in valuable and expensive oil samples. It is observed that the characteristic odor notes of argan oil are related to the few most powerful aroma-active compounds using the aroma extract dilution anal. technique. The aroma-active compounds of Moroccan argan oil are sensorily and instrumentally analyzed via gas chromatog.-mass spectrometry-olfactometry (GC-MS-O). The purge and trap extraction (PTE) method is used for the extraction of volatile components. A total of 19 aroma compounds are detected as aroma active by AEDA method among 35 volatiles. Characteristic odor notes in argan oil are found to be roasty, nutty, fatty, earthy, and cheesy.
