UC Davis researchers are providing more insight into how grape skins and seeds, which usually go to waste during the making of chardonnay wine, may be a valuable and healthful ingredient in new food products.

A review paper published by the Journal of Agricultural and Food Chemistry outlines how chardonnay marc can serve as a model for developing plant-based natural product food ingredients, and perhaps make upcycling agricultural byproducts relevant to other post-harvest processing scenarios.
