Infrared spectroscopy is widely applied in the wine sector. The medium infrared (MIR) spectral region between 1800 and 900 cm-1 is very informative for polyphenols. The authors caaried out a work aimed to perform an in-depth analysis of this spectral region of polyphenolic wine extracts. To this goal evolution of the polyphenolic fractions of white (Vermentino) and red (Cannonau) typical Sardinian wines was studied during wine-making.
Mycological contamination of food products is a common problem in the food industry, associated with implications for consumer health. Red wine is regarded as an alcoholic beverage with health benefits, notably for the circulatory system. However, in spite of its health-promoting properties, it can also be a source of toxic substances. Wine is a documented source of ochratoxin A, which is one of the ubiquitous, highly toxic secondary metabolites produced by filamentous fungi. It is the only mycotoxin for which a regulatory maximum level in wine has been established. There are no legal regulations on the content of other mycotoxins in wine, as a product with an increased risk of mycological contamination, and so their levels are not monitored. The aim of this study was to determine the concentrations of ochratoxin A (OTA), deoxynivalenol (DON) as well as T-2 and HT-2 toxins in dry red wines.
This is the last post of 2019. The second year of Science & Wine existence, time for a brief reflection. This was a great year!
Christmas. A time for joining the family to celebrate life. Usually these family meetings are around a table this is also a time known for an overeating behaviour. The rule should be “Moderation”. Our health depends on what we eat and if we wish celebrate Christmas for many years and in good health, one of our resolutions for 2020 must be eat healthy.
This is the post number 100. One hundred of weekends that I spend writing, reading, illustrating, editing and publishing the posts. The time that I spent do it is just part of the time I stole to the family, special to my youngest daughter, so today I decided to involve her in this project. The illustration is her authorship.
Today ended the “Mostra da Universidade do Porto” that is an annual exhibition where the University of Porto schools promote their educational offer. The most repeated question made by high school students was “What can I do with that degree?”. I always answer, “All that you want”. I really believe it! Someone with cognitive and hard work capacities, can do anything with the tools acquire during the course. Joining creativity and courage, then are congregated the conditions to a brilliant career. Of course, that a personal career also depends in the networks that each one can establish.
One of the main goals of this blog is to inform people about the latest news in wine research area. People need to know the state-of-the-art to be able to apply that knowledge in their works on the way to evolution and success. Ranking the papers according with the number of times that they were cited, is one of the ways to measure the impact of several studies in a specific area of research. I ordered the papers according with the number of times that they were cited in the period between January of 2015 and December of 2017. The results were obtained in a search performed in Web of Science Core Collection, the field tag used was “wine” and the results were filtered to list all Highly Cited in Field or Hot Papers in Field.
