Abstract

Wine pomace contains high amounts of bioactive compounds, mainly polyphenols, with varying concentrations depending on multiple factors. This research aimed to determine differences in the content of polyphenols and antioxidant activity of the wine raw materials and pomace of Japanese quince (‘Rasa’), aronia (seedlings), and grape (‘Hasansky Sladky’) and between harvest years (2021, 2022), as well as between fruits and pomace. Pomace from aronia and Japanese quince was obtained after maceration for 5 and 7 days, respectively, while grape pomace was collected on the day of harvest. The polyphenol content of fruits and pomace varied significantly between harvest years. Aronia had the highest total polyphenol content in fruits (989 mg GAE 100 g-1) and pomace (1022 mg GAE 100 g-1), followed by Japanese quince (625 and 722 mg GAE 100 g-1) and grapes (390 and 481 mg GAE 100 g-1). Aronia fruits and pomace had higher antioxidant activity. Compared to the fruits, aronia pomace had less chlorogenic acid and neochlorogenic acid. Flavanols were the main polyphenols in the Japanese quince, showing lower content in the pomace when compared to fruits, except catechin content was higher. The content of anthocyanins and flavonols was higher in the rosé wine pomace than in the fruits of grapes.
杂交葡萄、赤霞珠、日本榅桲(Chaenomeles japonica)和日本榅桲(Chaenomeles japonica)酿酒原料和果渣中的多酚成分和抗氧化活性
葡萄酒渣含有大量生物活性化合物,主要是多酚,其浓度因多种因素而异。本研究旨在确定日本榅桲('Rasa')、秋海棠(幼苗)和葡萄('Hasansky Sladky')的葡萄酒原料和果渣中多酚含量和抗氧化活性的差异,以及不同收获年份(2021 年、2022 年)之间的差异,以及水果和果渣之间的差异。秋海棠和日本榅桲的果渣分别在浸渍 5 天和 7 天后获得,而葡萄果渣则在收获当天收集。不同收获年份的果实和果渣中的多酚含量差异很大。欧龙眼果实(989 毫克 GAE 100 克-1)和果渣(1022 毫克 GAE 100 克-1)中的总多酚含量最高,其次是日本榅桲(625 和 722 毫克 GAE 100 克-1)和葡萄(390 和 481 毫克 GAE 100 克-1)。秋海棠果实和果渣具有较高的抗氧化活性。与水果相比,秋海棠果渣的绿原酸和新绿原酸含量较低。黄烷醇是日本榅桲中的主要多酚,与果实相比,果渣中的黄烷醇含量较低,但儿茶素含量较高。桃红葡萄酒果渣中的花青素和黄酮醇含量高于葡萄果实。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
