New types of wine-derived beverages are now in the market. However, little is known about the impact of ingredient formulation on aroma release during consumption, which is directly linked to consumer preferences and liking. In this study, the optimization and validation of a retronasal aroma-trapping device (RATD) for the in vivo monitoring of aroma release was carried out. This device was app...

Direct injection for gas chromatographic profi ling of alcoholic beverages is usually preferable, but where spirits and liquors contain appreciable amounts of non-volatile material, some mode of pre-treatment may be required to avoid both inlet and column contamination. This consideration applies in particular to products aged for extended periods in wooden barrels and especially products conta...

Two chemical approaches, Tenax extraction and matrix solid-phase microextraction (matrix-SPME), were compared to assess the bioavailability of hydrophobic contaminants from sediment. Hexachlorobiphenyl, DDE, permethrin, chlorpyrifos, and phenanthrene were individually spiked into two sediments differing in physical characteristics. Bioaccumulation was determined by exposing the oligochaete, Lum...

Genome data as well as biochemical studies have indicated that--as a peculiarity within hyperthermophilic Archaea--Thermoproteus tenax uses three different pathways for glucose metabolism, a variant of the reversible EMP (Embden-Meyerhof-Parnas) pathway and two different modifications of the ED (Entner-Doudoroff) pathway, a non-phosphorylative and a semi-phosphorylative version. An overview of ...

A two-year-old cavalier King Charles spaniel was presented with accidentally observed larvae in fresh feces, which were identified as rat-tailed of the common drone fly (Eristalis tenax). This can cause facultative myiasis both humans and animals. Although myasis has already been described humans, to authors’ knowledge, this is first description such a case an animal Belgium.
