AI Article Synopsis
- The study investigates how different factors in the winemaking process affect melatonin and its precursors in Romanian wines, given melatonin's antioxidant properties.
- A new method using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was developed to accurately measure melatonin, serotonin, and l-tryptophan in these wines.
- The findings suggest that winemaking variables such as grape variety, vineyard location, and aging can influence melatonin levels, potentially leading to enhancements in wine antioxidant activity through optimized fermentation techniques.
Article Abstract
Because melatonin has strong antioxidant activity and wine is an alcoholic beverage of economic relevance, in the present work, the impact of some variable parameters that may occur in the winemaking process on the concentrations of melatonin and its precursors in Romanian wines was studied. Therefore, a sensitive and selective high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the simultaneous analysis of melatonin, serotonin, and l-tryptophan, and some method performance parameters including selectivity, detection limit, precision (by comparing with an alternative HPLC-FL method), accuracy, and robustness were validated. These determinations are significant and the final amounts of analytes are dependent on the microorganisms involved in the winemaking process, the grape variety, geographic regions of vineyards, and aging of wines. In the future, the method may be useful to increase the melatonin content and the antioxidant activity in wines by improved steps in the winemaking process, especially based on application of selected yeasts and improved fermentation conditions.

The winemaking process generates huge amounts of waste every year. Fermented grape pomace, the major by-waste product, holds significant value due to its chemical composition and technological properties. In this study a multi-omics approach was employed for the detailed molecular characterization of fermented grape pomace from Montepulciano grape, a widely used Italian red grape variety.

Nitrogen limitations in the grape must be the main cause of stuck fermentations during the winemaking process. In , a genetic segment known as region A, which harbors 12 protein-coding genes, was acquired horizontally from a phylogenetically distant yeast species. This region is mainly present in the genome of wine yeast strains, carrying genes that have been associated with nitrogen utilization.

The increase in the incidence of hyperglycemia and diabetes poses the challenge of finding cost-effective natural inhibitors of starch digestion enzymes. Among natural compounds, phenolics have been considered as promising candidates. The aims of this study were as follows: (a) to investigate the effectiveness of the inhibition of different winemaking byproducts towards intestinal brush border α-glucosidase and pancreatic α-amylase in vitro; (b) to calculate an efficacy index relative to the standard acarbose for the phenolic pool of winemaking byproducts, as well as for isolated phenolic compounds and for the phenolic pools of different plants studied in the literature, in order to rank winemaking byproducts with respect to the reference drug and other natural alternatives.

Wine lees, the second most significant by-product of winemaking after grape pomace, have received relatively little attention regarding their potential for valorization. Despite their rich content in bioactive components such as β-glucans, industrial utilization faces challenges, particularly due to variability in their composition. This inconsistency impacts the reliability and standardization of final products, limiting broader adoption in industrial applications.

Article Synopsis
- This study investigated gene expression in 23 yeast strains across six subpopulations to understand how winemaking conditions and anthropization influence traits like lactic acid production.
- The analysis showed that different strains have unique transcriptomic profiles linked to fermentation processes, highlighting how anthropized environments lead to metabolic specialization.
- Findings suggest that understanding these gene expression differences can optimize biological acidification and enhance specific traits needed in modern winemaking, such as improved production of lactic acid and other important metabolites.
