Possibility of fiber hemp essential oil utilization as an aroma and fragrance additive

Abstract

Essential oils of two fiber hemp cultivars (Fedora 17 and Helena) were investigated in order to determine their composition and their suitability for utilization as fragrance and aroma additive. The fresh fiber hemp inflorescences were hydrodistilled and obtained essential oils were characterized by GC-MS. In both cultivars, there were 45 compounds detected, of which monoterpene hydrocarbons were most abundant (36.7% in Fedora 17 and 37.44% in Helena). In significant percentage there were -pinene (5.67% in Fedora 17 and 10.12% in Helena) which has woody fragrance, myrcene which has pleasant herbaceous aroma (9.18% in Fedora 17 and 10.14% in Helena) and terpinolen with pine fragrance (8.26% in Feodra 17 and 4.63% in Helena). Limonene, with its fruity aroma, was present with 1.36% in Fedora 17 and 1.19% in Helena. Among sesquiterpenes most abundant was bitter E- - caryophyllene. Non-psychoactive cannabidiol (CBD) was present with 9.30% and 7.22% in Fedora 17 and Helena, respectively, while psychoactive tetrahydrocannabinol (THC) was not detected. Based on investigated essential oils composition, Fedora17 and Helena possess terpenes with desirable scent, which makes them favorable for application as flavor and fragrance additive.
