Grape seed residues represent the raw material to produce several value-added products including polyphenol-rich extracts with nutritional and health attributes. Although the impact of variety and environmental conditions on the polyphenol composition in fresh berries is recognized, no data are available regarding grape seed residues. The chemical composition of grape seed residues from wine distilleries in France, Spain and Italy was characterized by mass spectrometry. Forty-two metabolites were identified belonging to non-galloylated and galloylated procyanidins as well as amino acids. Polyphenol concentrations in the red varieties originated from Champagne or Veneto were twice higher than in white varieties from the Loire Valley. The chemical profiles of grape seed residues were mainly classified according to the color variety with galloylated procyanidins as biomarkers of white varieties and non-galloylated procyanidins as biomarkers of red ones. The present approach might assist the selection of grape seed residues as quality raw materials for the production of polyphenol-rich extracts.
葡萄籽残渣是生产多种增值产品的原料，包括具有营养和健康特性的富含多酚的提取物。尽管人们认识到品种和环境条件对新鲜浆果中多酚成分的影响，但关于葡萄籽残渣的数据却尚无可用。通过质谱对法国、西班牙和意大利葡萄酒厂的葡萄籽残渣的化学成分进行了表征。鉴定出了42种代谢物，它们属于非没食子酰化和没食子酰化原花青素以及氨基酸。来自香槟或威尼托的红色品种中的多酚浓度比卢瓦尔河谷的白色品种中的高出两倍。葡萄籽残渣的化学图谱主要根据颜色品种进行分类，没食子酰化原花青素作为白色品种的生物标志物，而非没食子酰化原花青素作为红色品种的生物标志物。本方法可能有助于选择葡萄籽残渣作为生产富含多酚提取物的优质原料。
