“…Additionally, the major volatile compounds identified in yellow passion fruit juice belong to the methyl and ethyl esters (WERKHOFF et al, 1998;CARASEK & PAWLISZYN, 2006). The levels of individual volatile compounds related to the aroma profile in food matrix are largely influenced by the extraction technique of the volatile fraction used in gas chromatograph analysis (BICCHI et al, 2008). Headspace sampling techniques are widely used for providing volatile profiles near the profiles experienced by humans.…”

“…Among the headspace techniques currently used for the extraction of aromatic volatiles, solid-phase microextraction (HS-SPME) has been applied for isolation of volatile compounds from fruits (BARBONI et al, 2009;PONTES et al, 2009;FIGOLI et al, 2010, ALVAREZet al, 2012. This technique is based on a dynamic process of adsorption of volatiles on the vapor phase in the sample headspace in a silica fiber coated with an adsorbent polymer and has high sensitivity in the volatiles extraction with a wide range of polarity (BICCHI et al 2008). In the static headspace sampling techniques (S-HS), the equilibrium between the sample and the headspace gas phase must be reached, and a gaseous fraction of the headspace is collected directly for analysis by gas chromatograph (SNOW & SLACK, 2002;WANG et al, 2008).…”

“…However, conventional SPME has some disadvantages of the fiber fragility and the limited sorption capacity. 2,3 Alternative approaches such as in-needle capillary adsorption trap (INCAT) or in-tube SPME, 4,5 solid phase dynamic extraction (SPDE) 6,7 and a needle trap device (NTD) [8][9][10] were reported, respectively. Such a device contains sorbent in the stainless steel needle.…”

“…Previously, the preparation of SPME fibers coated with PEG was studied by several researchers. 7,[16][17][18] In this study, we have designed and fabricated a new inneedle microextraction device using a nichrome wire coated with PEG modified with PDMS sorbent phase to improve effectively the extraction efficiency of both polar and nonpolar compounds in a single experiment. The sol-gel technique 19,20 was used to prepare a nichrome wire coated with sorbent.…”

A new needle-based device for headspace wire coated in-needle microextraction (HS-WC-INME) was fabricated using a nichrome wire coated with poly(ethylene glycol) (PEG) and poly(dimethylsiloxane) (PDMS) mixture. The proposed needle device was applied for the determination of volatile compounds in lavender and lavandin essential oils by gas chromatography. Fundamental parameters such as needle design, conditions of extraction and desorption were optimized along with the validation of the extraction and desorption efficiency. The optimal conditions were 30 min extraction at 50 o C and 2 min desorption at 240 o C. The calibration curves showed good linearity with the suitable values of the coefficients of determination (r 2 ) greater than 0.99. The limits of detection for linalyl acetate, -caryophyllene, linalool and (+)-limonene were 7.15, 9.04, 10.79 and 22.26 ng, respectively. Analytical recoveries were acceptable in the test samples, varying from 86.7% to 108.0%. The values of relative standard deviations for run to run showed range less than 0.9% while 3.9% through 7.2% for needle to needle. The proposed PEG-PDMS coating could be more suitable than PDMS coating to extract particular polar groups such as alcohols.

Headspace micro solid phase extraction using mulberry paper bag (HS-MPB-µ-SPE) has been developed and validated for the analysis of volatile flavor compounds from five spice by gas chromatography-mass spectrometry (GC/MS). HS-MPB-µ-SPE was performed with adsorbent particles enclosed inside a mulberry paper bag. Four different kinds of adsorbents such as Tenax TA, Porapack Q, dimethylpolysiloxane and polyethylene glycol were tested. The extraction solvents compared were petroleum ether, methylene chloride, and chloroform. Better results were obtained when Tenax TA and petroleum ether were used. The limit of detection (LOD) and the limit of quantitation (LOQ) were in the range of 1.3 ng/mL and 4.3 ng/mL, respectively, for o-cymene as a model compound of monoterpene. Proposed method showed good reproducibility (3.3%, RSD) and good recoveries (94.0%). The HS-MPB-µ-SPE is very simple to use, inexpensive, rapid, requires small sample amounts and solvent consumption. Because the solvent for extraction is reduced to only a very small volume (0.6 mL), there is minimal waste or exposure to toxic organic solvent and no further concentration step. This method allows successful characterization of the headspace in contact with the five spice sample. Strong trans-anethole from star anise or fennel is a characteristic flavor of five spice powders. HS-MPB-µ-SPE combined with GC/MS can be a promising technique for the broad spectrum measurement of volatile aroma compounds from solid spices.
