摘要

葡萄中的多酚成分对人类健康的益处已得到公认。由于葡萄生产过剩、葡萄酒销量下降以及世界社会经济形势的影响,酿酒葡萄的价值提升成为一项很有前景的战略,以增加这一天然产品的价值。本研究的目的是研究体外胃肠道消化对不同葡萄品种(添普兰尼洛、格拉西亚诺、马图拉纳丁塔和洪达拉比祖里)的果皮和种子提取物的抗氧化能力和多酚成分的影响。经过体外胃肠道消化后,所有葡萄品种种子多酚提取物的总酚含量(TPC)都显著下降。降幅最大的是丹魄,从 108 ± 9 毫克/克干物质(dm)降至 50 ± 3 毫克/克干物质(dm)。该品种的抗氧化能力也下降了 90%,降幅最大。不过,所有果皮多酚提取物的 TPC 都有所增加。变化最大的也是添普兰尼洛。其变化范围为 10.1 ± 0.8 至 55.1 ± 0.9 毫克/克 dm。在红葡萄品种中,添帕尼优果皮多酚提取物中的未消化花青素含量最低,但生物可接受性指数(BI)最高,达到 77%。对于黄烷醇、黄酮醇和原花青素,种子多酚提取物在肠道阶段的生物可及性指数从(+)-没食子酸表儿茶素的11%到原花青素A2的130%不等。这项研究结果表明,葡萄皮提取物和葡萄籽提取物是生物可利用的抗氧化多酚的可靠来源,可用于开发具有特定功能的抗氧化补充剂,具体功能取决于葡萄品种。

Bioaccessibility and Antioxidant Capacity of Grape Seed and Grape Skin Phenolic Compounds After Simulated In Vitro Gastrointestinal Digestion

Grapes present recognized beneficial effects on human health due to their polyphenolic composition. The grape overproduction together with the wine sales down and the world socioeconomic situation makes the wine grape valorization a promising strategy to give an added-value to this natural product. The objective of the present work was to study the influence of in vitro gastrointestinal digestion on antioxidant capacity and polyphenolic profile of skin and seed extracts of different grape varieties (Tempranillo, Graciano, Maturana tinta and Hondarrabi zuri). After in vitro gastrointestinal digestion, total phenolic content (TPC) of seed polyphenolic extracts decreased significantly for all the varieties. The highest decrease was for Tempranillo going from 108 ± 9 to 50 ± 3 mg / g dry matter (dm). This variety also showed the highest decrease of 90% in antioxidant capacity. However, for all the skin polyphenolic extracts there was an increase in TPC. The highest variation was also for Tempranillo. It varied from 10.1 ± 0.8 to 55.1 ± 0.9 mg / g dm. Among red varieties Tempranillo skin polyphenolic extract showed the lowest undigested anthocyanin content but the highest bioaccessibility index (BI) of 77%. For flavanols, flavonols and procyanidins the seed polyphenolic extracts showed a BI at the intestinal phase between 11% for (+)-epicatechin gallate to 130% procyanidin A2. The results of this study suggest that grape skin extracts and grape seed extracts are a reliable source of bioaccessible antioxidant polyphenols, to be used for the development of antioxidant supplements with specific functionalities depending on the grape variety.
