I decided to write this post after reading an article in the Portuguese newspaper, Expresso, which highlighted the negative health effects and cancer risks associated with the consumption of small amounts of alcohol. It is a personal reflection of a woman, mother, teacher, and scientist based on my perspective on the world and scientific evidence. Discussion about alcohol consumption? Yes, but for there to be results, common sense must prevail.
Ireland introduced legislation on May 22, 2023, requiring alcohol products to carry health warning labels. This aims to inform consumers about alcohol’s health risks. However, the effectiveness of such labels is debated, especially for wine due to its cultural significance, and according to scientific data beliefs in its health benefits may not be easily influenced by these warnings.
Each year, 20 million tons of wine by-products are generated, corresponding to 30% of the total quantity of vinified grapes. Wine by-products are a source of healthy bioactive molecules, such as polyphenols and other molecules (pigments, fibers, minerals, etc.). The abundance of bioactive compounds assures a promising future for nutritional foodstuff production. Wine by-products can be used to fortify aromatized waters and infusions, bread, pasta, dairy products, alcohol, sugary beverages, and processed foods. These innovative products are part of the Mediterranean Diet and are of great interest to both human and environmental health. Read more that http://science-and-wine.com/
This post summarizes a study carried out with the aim of optimizing the operating conditions and to study the scale-up and the feasibility of the supercritical fluid extraction process for polyphenols from grape pomace, the main solid byproduct of the wine industry. An economic evaluation of the process indicated the feasibility of an industrial SFE plant with a capacity of 500 L for producing in 60 min an extract with an expected phenolics’ concentration of approximately 133 gGAE/kg extract at an estimated 67€ /kgextract cost of manufacturing. Notably, all values are better than those currently reported in the literature
As promised, we will maintain the organization of the World Congress every two years. The 3rd World Science & Wine Congress will be from 14 to 16 June 2023 in Vila Nova De Gaia and the Douro region. The topic for this scientific meeting here will be “Sustainability of wine production and food systems in the Mediterranean region”.
Vine leaves, which are produced fresh, brined or fermented from the leaves of Vitis Vinifera in Türkiye are an important food. Sulfur is used as a pesticide and sulfur compounds can be used as additives during the growing and processing of the vine leaves. These sulfur sources cause positive results on carbon disulfide (CS2) measurements by GC-MS. Therefore, the main objective of the present study was to investigate the effects of residues of sulfur or sulfur compounds on dithiocarbamate analysis methods based on CS2 measurement.
Grape pomace, a wine-making by-product rich in dietary fiber and total phenolic compounds, is a potential functional ingredient in the fortification of baked goods. Grape pomace improved the nutritional values of fortified breadsticks and changed the rheology of dough and breadsticks’technological properties without affecting sensory acceptability.
After two successive postponements, the fifth edition of Wine Active Compounds (WAC) 2021 happened in the Palace of the Dukes of Burgundy in Dijon, France, from Wednesday June 29 to Friday July 1, 2022, under the auspices of the UNESCO Chair “Culture & Traditions of Wines” and the Institut Jules Guyot at University of Burgund.
This study sought to evaluate the possibility of using grape pomace, a waste material from wine production, for the preparation of cosmetic components. Following the existing clear research trend related to improving the safety of cleansing cosmetics, an attempt was made to determine the possibility of preparing model shower gels based on grape pomace extract. The results obtained showed that the extracts based on waste grape pomace contained a number of valuable cosmetic compounds (e.g., organic acids, phenolic compounds, amino acids and sugars), and the model products basis on them provided colorful and safe natural cosmetics.
Wine is an essential part of European culture. Unfortunately, the consumption of alcohol, such as wine, can have negative health effects. Health warning labels (HWLs) are increasingly presented as a measure to warn consumers of the threat alcohol poses to their health. At present, only a few countries in Europe have introduced mandatory HWLs on wine bottles. This may be due to the cultural and economic significance of wine and the European public’s refusal to accept HWLs on a product like wine. To investigate this issue, the authors conducted an online experiment in the German-speaking part of Switzerland and assessed the perception of risk in participants who were presented wine bottles featuring different types of HWLs. They also studied how health beliefs and cultural worldviews influence the perception and acceptance of HWLs. The study revealed a small effect of HWLs on consumers’ risk perception. There was no difference between a simple text-only HWL and a label featuring a deterring picture (image-and-text HWL). The major determinants of HWL acceptability were cultural worldviews and health beliefs. That is, participants who opposed government intervention for collective wellbeing and espoused a belief in the health benefits of wine were less likely to accept HWLs on wine. More research is needed to assess the effectiveness of HWLs in real-life situations and the importance of culture to the acceptance of such a public intervention measure.
