Influence of Oak Chips and Oak Barrel Ageing on Volatile Profile in Chardonnay Wine of Romania [PDF]

Applied Sciences, 2021
The influence of the addition of oak chips and barrel ageing on basic wine parameters and volatile compounds of Chardonnay wines has been studied. Chardonnay wines were obtained by the traditional wine-making process. Oak chips (4 g/L—non-toasted and light toasted) were added at the final stage of the winemaking process for ageing 1, 2 and 3 months ...

Indirect effects of tending ants on holm oak volatiles and acorn quality. [PDF]

Plant Signal Behav, 2011
The indirect effect of ants on plants through their mutualism with honeydew-producing insects has been extensively investigated. Honeydew-producing insects that are tended by ants impose a cost on plant fitness and health by reducing seed production and/or plant growth.

Field observations of volatile organic compound (VOC) exchange in red oaks [PDF]

Atmospheric Chemistry and Physics, 2017
Abstract. Volatile organic compounds (VOCs) emitted by forests strongly affect the chemical composition of the atmosphere. While the emission of isoprenoids has been largely characterized, forests also exchange many oxygenated VOCs (oVOCs), including methanol, acetone, methyl ethyl ketone (MEK), and acetaldehyde, which are less well understood.

Reuse of oak chips for modification of the volatile fraction of alcoholic beverages [PDF]

LWT, 2021
Abstract New or used barrels can be applied in ageing of alcoholic beverages. Compounds adsorbed in wood migrate between beverages along with wood extractives. As barrel ageing is costly and time-consuming, processes using wood fragments have been gaining interest. These generate wood residues for which the reuse is still not well established.

Evaluation of Volatile Compounds during Ageing with Oak Chips and Oak Barrel of Muscat Ottonel Wine [PDF]

Processes, 2020
The aim of this work was to compare the variations of alcohols compounds in white wine Muscat Ottonel variety aged in the presence of untoasted oak chips, toasted oak chips and untoasted barrel, considering three ageing periods—30, 60, and 90 days. The liquid-liquid extraction and gas chromatography coupled to mass spectrometry were used to compare the

Volatiles in Distillates of Cider Aged in American Oak Wood [PDF]

Journal of Agricultural and Food Chemistry, 1996
kinds of cider aged in oak wood. During aging, a significant increase was detected in the concentration of diethyl butanedioate, ethyl 3-methylbutanoate, esters of long-chain fatty acids, and 1-hexanol; in contrast, the acetate esters and long-chain fatty acids decreased.

Application of Hanseniaspora vineae Yeast in the Production of Rosé Wines from a Blend of Tempranillo and Albillo Grapes

Fermentation, 2021
Hanseniaspora vineae is an apiculate yeast that can be used for the production of interesting commercial wines, due to its contribution of fermentative volatiles. This paper presents a detailed comparative study of the use of H.

Symbiotic Fungi of an Ambrosia Beetle Alter the Volatile Bouquet of Cork Oak Seedlings

Phytopathology®, 2022
In Portugal, fungal symbionts of the ambrosia beetle Platypus cylindrus affect tree vigor of cork oak (Quercus suber) and are linked with the cork oak decline process. Fungal symbionts play crucial roles in the life history of bark and ambrosia beetles and recent work indicates complex interactions on the fungal and plant metabolic level.

Oak Kernels—Volatile Constituents and Coffee-Like Beverages

Journal of Agricultural Science, 2018
Modern consumers are much aware of potential health benefits of food and food ingredients. The food industry has been constrained to develop new products with improved sensory, nutritive and functional characteristics. In this work a potential use of English (Quercus robur) and Turkish oak (Quercus cerris) kernels as functional food components was ...

Volatile composition of aged wine in used barrels of French oak and of American oak

Food Research International, 2002
This investigation studied the behaviour of the barrels at the completion of their cycle of use (5-6 years old) on the volatile composition of a red wine. Results showed that compounds from the wood such as vanillin, syringaldehyde and trans--methyl--octalactone, which are important for the aroma of the wine, were lower than their threshold of ...
