These wastes cause environmental problems such as pollution of surface and groundwater, oxygen depletion and use by disease-carrying vectors, all of which have harmful effects on animals. Many studies have reported that grape wastes such as peel, seed and leaf have a rich content of phenolic compounds. Extracts obtained from wastes can be used functionally in bakery, dairy and gummy candy production. In our country, grape-based food supplement products are offered with contents such as resveratrol, grape seed extract or grape seed oil. Grape by-products contain polyphenols, dietary fiber and oil that can be used in the treatment of many diseases. Current research has shown that foods produced with grape by-products or extracts hold great promise in making the grape products and vineyard sector more sustainable as well as preventing chronic diseases.
