Volatile emerging contaminants in melon fruits, analysed by HS-SPME-GC-MS

Food Additives & Contaminants: Part A, 2017
The aim of this research was to develop and validate a headspace-solid phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) method for the determination of volatile emerging contaminants in fruit. The method showed good precision (RSD ≤ 14%) and satisfactory recoveries (99.1-101.7%) and LOD and LOQ values ranging between 0.011-0 ...

Decoding carob flavor aroma using HS–SPME–GC–MS and chemometrics

European Food Research and Technology, 2020
Ceratonia siliqua L. is quite popular for the sweetness of its fruit (“natural chocolate”) and the strong, persistent, characteristic odor that associates not only carob fruit, but also its traditional food products. This is due to the emission of an array of volatile organic compounds (VOCs).

The Optimization and HS-SPME/GC-MS Analysis in Pear Fruit

Advanced Materials Research, 2014
Solid-phase microextraction (SPME) is a rapid sample preparation in volatile analysis. The aromatic volatile compositions of ‘Kuerle’ were analyzed using SPME and gas chromatography-mass spectrometry (GC-MS). The effect of different types of fibers, extraction time, and extraction temperature on the volatile results were compared and discussed.

Flavor evolution and identification of the warmed-over flavor (WOF) in pre-cooked goose meat by means of HS-SPME-GC-MS and GC-IMS.

Food Chemistry
This study explored the flavor evolution of pre-cooked goose meat during storage, focusing on lipid oxidation's impact on warmed-over flavor (WOF). Using electronic nose, GC-IMS, and SPME-GC-MS to characterize volatile organic compounds (VOCs), 60 VOCs ...

Untargeted and Targeted Discrimination of Honey Collected by Apis cerana and Apis mellifera Based on Volatiles Using HS-GC-IMS and HS-SPME-GC-MS.

Journal of Agricultural and Food Chemistry, 2019
Fraudulent acts regarding honey authenticity that use Apis mellifera honey as a substitute for Apis cerana honey have garnered considerable concern in China and triggered a trust crisis from consumers.

Volatiles from flowers of Photinia serrulata by HS-SPME-GC-MS

Chemistry of Natural Compounds, 2013
Photinia serrulata Lindl. belongs to the Rosaceae family and is distributed in Shanxi, Gansu, Anhui, Jiangsu, Henan, and Hunan Provinces in China [1]. Phytochemical research showed that triterpenoids and cyanophoric glycosides, for example, ursane triterpenoids and analogs, ursolic acid, oleanolic acid, prunasin, and saponin, were the main compounds in

Determination of terpene alcohols in Sicilian Muscat wines by HS-SPME-GC-MS

Natural Product Research, 2013
Muscat is a grape family used to obtain several sweet, aromatic white dessert wines common in the Mediterranean area. Currently, three Sicilian cultivars (all classified DOC) are known: 'Moscato di Siracusa' the oldest and very rare today; 'Moscato di Noto', a modern derivative of the first and finally 'Moscato di Pantelleria', now the most common ...
