Described herein is a system, process, nutrient-rich products, and uses thereof which are generated by the conversion of fruit winery derivatives into nutrient-rich products in an ecological manner. Integration of this system into a winery assists the winery to manage its previously-considered waste in an ecological manner, which can also optionally provide the winery with a novel revenue stream. The system, and process are used to convert winemaking derivatives into bioactive nutrient-rich products and/or food ingredients comprising antioxidants and other bioactive molecules that reside within the marc and lees. These nutrient-rich products can be used as natural flavour, texture and color enhancers, in addition to nutritional ingredients to fortify processed foods and consumer recipes. They can also be used as health supplements and in the cosmetic industry.
