A new study in the Journal of Food Science, published by the Institute of Food Technologists (IFT), shows that grape skin and seeds generated from winemaking—known as wine pomace—are a good source of antioxidant dietary fiber and can be used to fortify various food products such as yogurts and salad dressings with enhanced nutritional value and extended shelf-life.
The researchers from Oregon State University analyzed pomace from Pinot Noir and Merlot wines to determine the most economically feasible ways to convert the rich source of antioxidants in pomace into compounds that can be used to fortify foods.
Drying pomace in the oven at 104 degrees Fahrenheit and air drying at 77 degrees Fahrenheit were considered highly acceptable and much less costly compared with freeze drying. These methods can easily be converted into large scale industrial applications for food processing purposes.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
