To investigate the headspace volatiles in shrimp head P. borealis, optimized conditions were evaluated for solid-phase microextraction coupled to gas chromatography-mass spectrometry method. SPME fibers of 100-μm polydimetylsiloxane, 65-μm polydimetylsiloxane-divinylbenzene, 75-μm carboxen-polydimetylsiloxane, and 50/30-μm divinylbenzene-carboxen-polydimetylsiloxane (DVB/CAR/PDMS) were compared. The influence of several parameters such as type of fibers, volume of sample, extraction time, extraction temperature, and state of samples was systematically investigated. Suitable reproducibility and sensitivity were achieved by combining DVB/CAR/PDMS of 50/30-μm thickness as the liquid phase of SPME, 1.5 g of shrimp head lyophilized powder, 40 OC of isolation temperature and 40 min of isolation time. A total of 62 volatile compounds have been confirm, including hydrocarbons, ketones, alcohols, aldehydes, esters, nitrogen-containing compounds and sulfur-containing compounds. 3,5-octadien-2-one (E,Z), 3,5-octadien-2-one (E,E), 1-penten-3-one, 6-octen-2-one, ethyl acetate and alcohols such as 1-penten-3-ol, 2-penten-1-ol and 1-octen-3-ol were predicted as key compounds for SH flavor.

Chemical Fingerprinting

Headspace solid-phase microextraction (HS-SPME), ultrasonic solvent extraction (USE) and solid phase extraction (SPE), followed by GC-FID/MS were used for screening of dandelion ( Taraxacum officinale Weber) honey headspace, volatiles and semi-volatiles. The obtained results constitute a breakthrough towards screening of dandelion honey since dominant compounds identified in the extracts were not previously reported for this honey type. Nitriles dominated in the headspace, particularly 3-methylpentanenitrile (up to 29.9%) and phenylacetonitrile (up to 20.9%). Lower methyl branched aliphatic acids and norisoprenoids were relevant minor constituents of the headspace. The extracts contained phenylacetic acid (up to 24.0%) and dehydrovomifoliol (up to 19.3%) as predominant compounds, while 3-methylpentanenitrile and phenylacetonitrile were detected in the extracts in minor abundance. Dehydrovomifoliol can be considered more characteristic for dandelion honey in distinction from phenylacetic acid. Low molecular aliphatic acids, benzene derivatives and an array of higher aliphatic compounds were also found in the extracts. The results of SPE/GC-FID/MS were very similar to USE/GC-FID/MS with the solvent dichloromethane. The use of all applied methodologies was relevant for the comprehensive chemical fingerprinting of dandelion honey volatiles.
