Evaluating cork coating homogeneity using hyperspectral imaging and texture ana...

Cork stoppers are vital for wine bottle packaging, allowing the sealing of the wine in the bottle. Cork stoppers are coated with a treatment to increase impermeability and lubrication, ensuring the quality and longevity of bottled wines. This coating, typically made of hydrophobic polymers, is applied during the final stages of cork production. The application of the coating material to the cork surface takes p...

Handheld near-infrared spectroscopy: state-of-the-art instrumentation and appli...

This present review article considers the rapid development of miniaturized handheld near-infrared spectrometers over the last decade and provides an overview of current instrumental developments and exemplary applications in the fields of material and food control as well as environmentally relevant investigations. Care is taken, however, not to fall into the exaggerated and sometimes unrealistic narrative of ...

High-throughput plant phenotyping: a role for metabolomics?

High-throughput (HTP) plant phenotyping approaches are developing rapidly and are already helping to bridge the genotype–phenotype gap. However, technologies should be developed beyond current physico-spectral evaluations to extend our analytical capacities to the subcellular level. Metabolites define and determine many key physiological and agronomic features in plants and an ability to integrate a metabolomic...

Yeast metabolic activity is sufficient to create a wine like aromatic feature i...

Wine is characterised by an underlying aromatic volatile profile, which allows human subjects to easily recognise the product as “wine” by smell alone. Yeast metabolism significantly contributes to wine organoleptic properties, and some yeast metabolism-derived compounds contribute to the vinous character of wine. However, the relative contribution of yeast and grape-derived metabolic compounds to the sensory p...

Strecker aldehyde formation in wine: new insights into the role of gallic acid,...

Strecker degradation (SD) leading to the formation of phenylacetaldehyde (PA) was studied in wine systems. New insights were gained by using two full factorial designs focusing on the effects of (1) pH and (2) temperature. In each design of experiments (DoE) three factors, glucose, gallic acid, and metals at two levels (present or absence), were varied while phenylalanine was kept constant. The obtained results...

Characterization of the pinewood nematode, bursaphelenchus xylophilus-pinus sys...

The pinewood nematode, Bursaphelenchus xylophilus, is one of the main threats affecting Portuguese maritime pine (Pinus pinaster). Several research teams have joined efforts to better understand the plant-nematode system. Over 150 essential oils (EO), as well as several EO fractions and decoction waters have been evaluated, Ruta graveolens, Satureja montana, Thymbra capitata, Thymus pulegioides, and T. vulgaris...

In vivo volatile organic compounds analysis in pinus pinaster after infection w...

The pine wilt disease (PWD), caused by the nematode Bursaphelenchus xylophilus, is devastating for Pinus pinaster plantations, leading to the loss of thousands of trees every year worldwide. Despite the important research efforts of the past decades, no effective strategies against the PWN have been developed and the physiological aspects related to disease resistance remain largely unknown. In this work, 1-yr-...

Application of a high-throughput process analytical technology metabolomics pip...

Metabolomics aims at gathering the maximum amount of metabolic information for a total interpretation of biological systems. A process analytical technology pipeline, combining gas chromatography-mass spectrometry data preprocessing with multivariate analysis, was applied to a Port wine "forced ageing" process under different oxygen saturation regimes at 60 °C. It was found that extreme "forced ageing" conditio...
