Latest Sugars in wine Stories
Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called 'cheaters' can exploit the system, taking without giving, with uncertain consequences for the social unit as a whole. A new study has found that a yeast colony dominated by non-producers ('cheaters') is more likely to face extinction than one consisting entirely of producers ('co-operators'). The findings, published April 30 in the open access journal PLOS Biology by Alvaro Sanchez and Jeff...
FECYT - Spanish Foundation for Science and Technology [ Watch The Video ] Researchers at the University of Seville (Spain) have developed a technique for estimating grape composition and variety using computer imaging. They have also put forward an index for identifying the ripeness of seeds without the need for chemical analysis. This new method can help to decide the best moment for picking. The normal procedure for identifying the sugar content of grapes involves chemical...
Preventing activity of a key enzyme in potatoes could help boost potato quality by putting an end to cold-induced sweetening, according to U.S. Department of Agriculture (USDA) scientists. Cold-induced sweetening, which occurs when potatoes are put in long-term cold storage, causes flavor changes and unwanted dark colors in fried and roasted potatoes. But long-term cold storage is necessary to maintain an adequate supply of potatoes throughout the year. Agricultural Research Service...
According to a new study released this week, people who consumed a bit of extra fructose baked into breads or sprinkled into drinks did not gain additional weight compared to those who had other types of carbohydrates instead as long as they ate the same number of total calories. However, when study participants supplemented a standard diet with a dash of extra calories in the form of straight fructose, they did gain weight, reports Reuters’ Genevra Pittman. John Sievenpiper, MD, PhD,...

SANTA FE, N.M., Nov. 17, 2011 -- The organic wine you are planning to buy for your holiday meal might not be as healthy as you thought. "As The People's Chemist, I exposed the lack of trust in the vitamin industry and now I found the organic wine industry can't be trusted either," said Shane Ellison, an award-winning chemist, author of OVER-THE-COUNTER NATURAL CURES, and founder of the People's Chemist.com: http://www.thepeopleschemist.com "Conventional winemakers add a number of toxins...
University of Illinois scientists have engineered a new strain of yeast that converts seaweed into biofuel in half the time it took just months ago. That's a process that's important outside the Corn Belt, said Yong-Su Jin, a University of Illinois assistant professor of microbial genomics and a faculty member in its Institute for Genomic Biology. "The key is the strain's ability to ferment cellobiose and galactose simultaneously, which makes the process much more efficient," Jin said....
A new study has created an analog of what researchers think the first multicellular cooperation might have looked like, showing that yeast cells"”in an environment that requires them to work for their food"”grow and reproduce better in multicellular clumps than singly.A team of researchers, led by Harvard professor Andrew Murray, found that cells of brewer's yeast that clumped together were able more effectively to manipulate and absorb sugars in their environment than were similar cells...
Researchers at Universitat Autonoma de Barcelona have developed an electronic tongue which can identify different types of cava wines, thanks to a combination of sensor systems and advanced mathematical procedures. The device automatically produces classifications similar to those of a sommelier.Cava varies in type according to the amount of sugar added with the expedition liqueur after secondary fermentation (which produces carbonic gas). Therefore it is useful to know the exact amount of...
For thousands of years, bakers and brewers have relied on yeast to convert sugar into alcohol and carbon dioxide. Yet, University of Wisconsin-Madison researchers eager to harness this talent for brewing biofuels have found when it comes to churning through sugars, these budding microbes can be picky eaters.Published online this week in the Proceedings of the National Academy of Sciences, a Great Lakes Bioenergy Research Center team identified several new genes that improve yeast's ability to...
