Abstract:

To study the differences and similarities of volatile compounds and aroma properties in Roman chamomile essential oil and German chamomile essential oil from Matricaria recutita, select the raw materials with fragrance suitable for industrial production, and establish the flavor database of aromatic plants, the volatile compositions and aroma properties in the two chamomile essential oil were analyzed by using gas chromatography-mass spectrometry (GC-MS) technology coupled with steam distillation (SD) for extraction of volatiles. A total of 49 volatiles were identified in the two chamomile essential oil, and 43 and 46 volatiles were identified in Roman chamomile essential oil and German chamomile essential oil, respectively. Esters, alcohols, and alkenes compounds were the main volatiles in the two essential oil, and the trans-pinocarveole, α-pinene, allyl tiglate and ethyl-2-methylcyclopropanecarboxylate were the common abundant volatile compounds, but the chamazulen was only identified in German chamomile essential oil. Combined with the results of sensory evaluation, Roman chamomile essential oil had better aroma properties, which were herbaceous, floral, fruity and sweet odors, and had weak irritation and earthy odors. By adding 0.5% (w/w) Roman chamomile essential oil to the beverage base, the herb-tea beverage could be well prepared with transparency, good fragrance flavor and stability. This research can provide scientific data for variety breeding, aroma quality improvement, chamomile essential oil extraction and preparation, and a theoretical basis for further development, utilization and industrialized production of chamomile from Matricaria recutita.

Key words: chamomile (Anthemis nobilis) essential oil, volatile compounds, sensory evaluation, aroma property, herb-tea beverage
