Grape pomace - the skins, stems and seeds of grapes that remain after pressing - contains compounds that could be used in food supplements. This is shown by a study at the University of Davis in California led by Professor Daniela Barile and Master's student Amanda Sinrod. According to the study, pomace from Chardonnay grapes, for example, contains significant amounts of oligosaccharides, a type of carbohydrate that is also found in human tissue. They are a component of breast milk and help promote gut and immune health.

"More research needs to be done," says Barile. "But the initial results are promising that Chardonnay pomace can be used as a source to develop supplements and other foods to support health."
