Accumulation of volatile oak compounds in a model wine stored in American and Limousin oak barrels

open access: yesAustralian Journal of Grape and Wine Research, 1998
Changes in concentration of oak-derived volatile compounds extracted into a model wine stored in four American and four Limousin oak barrels were measured over a 93-week period. The accumulation curves for cis- and trans-oak lactone and eugenol were asymptotic and virtually identical in shape. Guaiacol was extracted more rapidly in the first six weeks,

Alternative Fuels from Forestry Biomass Residue: Torrefaction Process of Horse Chestnuts, Oak Acorns, and Spruce Cones

open access: yesEnergies, 2020
The global energy system needs new, environmentally friendly, alternative fuels. Biomass is a good source of energy with global potential. Forestry biomass (especially wood, bark, or trees fruit) can be used in the energy process. However, the direct use

Analysis of Volatile Components of Varietal English Wines Using Stir Bar Sorptive Extraction/Gas Chromatography-Mass Spectrometry

open access: yesBeverages, 2017
Aroma is an important property of wine and it can be influenced significantly by enological practices. The aim of this work was, by use of stir bar sorptive extraction/gas chromatography-mass spectrometry (SBSE/GC-MS), to compare semi-quantitative ...

Irreversible impacts of heat on the emissions of monoterpenes, sesquiterpenes, phenolic BVOC and green leaf volatiles from several tree species [PDF]

open access: yesBiogeosciences, 2012
Climate change will induce extended heat waves to parts of the vegetation more frequently. High temperatures may act as stress (thermal stress) on plants changing emissions of biogenic volatile organic compounds (BVOCs).
