中文摘要:

      许多水果在加工过程中会产生大量的副产物, 如葡萄酒酿造过程中产生的葡萄果渣(grape pomace,GP), 由于其中含有丰富的生物活性物质, 如多酚、膳食纤维、有机酸和不饱和脂肪酸等, 已成为医药、化妆品和食品工业提取植物活性物质的廉价来源。尤其是酚类化合物受到越来越多的关注, 葡萄渣中的酚类化合物是一类次生代谢产物, 主要包括类黄酮、花青素和白藜芦醇等, 很多研究已经证实这些酚类化合物具有抗氧化、抗菌、抗病毒、抗炎和抗癌等生物活性, 因此, 如何从葡萄渣中提取多酚化合物并将其开发成功能性食品配料, 成为越来越多的企业和学者的关注。在此本文对GP多酚的组成分布、生物活性、在食品中的稳定性及其应用等进行了较全面的总结, 旨在为葡萄渣多酚功能性食品的开发提供参考。

英文摘要:

      Lots of by-products can be produced from the processing of fruits. Grape pomace (GP) is such a by-product from wine industry. GP contains abundant bioactive phytochemicals, such as phenolics, dietary fiber, organic acid and unsaturated fatty acids. Therefore, GP has been an inexpensive source for the extraction of phytochemicals which are used in the pharmaceutical, cosmetic, and food industries. Especially the phenolics have attracted more and more attentions. These phenolics are secondary plant metabolites with potential beneficial effects on human health because of their antioxidant activity and antimicrobial, antiviral, anti-inflammatory and anticancer properties. Thus more and more efforts have been made to extract the phenolics from GP and to use it as the materials of the functional food. This review summarizes current knowledge on the composition distribution of GP polyphenols, their biological activities, their stability in food system, and their applications in food. The aim is to provide a reference for the development of new functional food from polyphenols of grape pomace.
