A green solvent-based DLLME/HPLC-MS method for the determination of 19 pesticides in wine samples has been developed. From the analysis of 11 commercial wines it was found that just in a bio sample the target compounds were not detectable or lower than quantification limit; as for the other samples, the most widespread and abundant pesticides were methoxyfenozide and boscalid, but their levels were much lower than the relative maximum residue levels.
The Mediterranean Diet (MedDiet) is a term used to identify a dietary pattern originating
from the unique multi-millennial interplay between natural food resources and the eating practices
of people living in the Mediterranean basin. The majority of MedDiet’s beneficial effects could be primarily related to its anti-inflammatory and antioxidant properties as well as the effectiveness of this dietary pattern in controlling waist circumference and obesity. Moreover, strict, and long-lasting adherence to the MedDiet as well as the beneficial effects of specific components (e.g., olive oil or its polyphenols) seem to emerge as useful insights for interventional improvements. These findings present further insights into the MedDiet’s resources and how it could strengthen overall public health.
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/
Grapevine grafting is an essential practice in viticulture and over the years, various bench grafting techniques have been developed to mechanize the nursery process and to increase the yield in number of viable cuttings. Bench grafting is a fundamental nursery practice that can potentially affect the quality of propagation material also in young decline associated to grapevine trunk diseases and has been recently reported to influence leaf symptoms development associated with diseases of Esca complex. The study aimed to investigate how three bench grafting methods can influence these phenomena.
From now on until our 3rd Science & Wine World Congress, on the first Sunday of each month, it will be published a post about Food Sustainability.
Today it will be about an interesting recent review written by Carlos Moreno-Miranda and Liesbeth Dries. In their paper entitled “Integrating coordination mechanisms in the sustainability assessment of agri-food chains: From a structured literature review to a comprehensive framework” they analyzed the state of the art in the assessment of agri-food supply chain sustainability based on a structured literature review.
This post summarizes the results of a study in which soluble polysaccharides from white and red grape skins were obtained to be evaluated as potential modulators of the unbalanced astringency of a Tempranillo red wine. The modulation of astringency was evaluated by a sensory panel, and it seemed to be related to the changes in the polyphenolic profile.
The main aim of the study summarized in this post was to perform a combined life cycle assessment and life cycle costing of the most used wine packaging systems in Italy. Packaging plays a key role in food and beverage production and supply chain, but the increasing volume of packaging used causes many environmental concerns. The wine sector is no exception, especially in Italy that is the largest producer in the world. From both the environmental and economical point of views, aseptic cartons and bag-in-box systems were the most sustainable alternatives, while the glass systems had the worst global performances due to the high weight and consequent huge energy consumption during bottle production. The size of the containers was the key factor that most affected the results both in environmental and economic terms.
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
The Wine Protected Designation of Origin (PDO) label is a European quality scheme that protects high quality wines by linking them to legally defined geographic areas and a set of specific production practices. Because of the tight relation between PDO wines and the specifications defined in the official regulatory documents, these products are highly susceptible to changes in climatic, environmental, or socioeconomic conditions. However, the content of these regulatory documents has never been systematically analysed and summarized in a single dataset. Here, we present the first geospatial inventory that organizes regulatory information about the 1177 wine PDO in Europe based on the documents from the official EU geographical indication register.
There is growing concern about the effects that a climate change may have on grape production and quality. This has led to studies carried out in different wine-growing areas of the world in which a trend of advance of phenology and harvest has been seen. However, the degree of change may not be the same in all areas and for all varieties. Given the projected climate change scenarios that involve changes in temperatures and in precipitation, it is necessary to deepen the knowledge of the response of different varieties to these changes and identify those varieties that may be more resilient, in addition to adopting other measures that can help mitigate the effects of warming.
