In this study, the chemical composition, bioactive compounds, minerals, and fatty acid composition of grape pomaces from 10 varieties with seed and skin of several grape varieties were investigated. The varieties Ekşikara, Çalkarası, and Marcaş exhibited significantly (p < .05) higher content of total phenolics (127.18, 138.41, and 147.51 mg/100 g, respectively), with a concomitant higher antioxidant activity (95.47, 96.71, and 98.47%, respectively) than other varieties. The HPLC analysis of phenolic compounds showed that chlorogenic acid, protocatechin, synergic acid, and ferulic acid were major constituents of the varieties. In addition, protocatechin content was significantly (p < .05) higher in Marcaş variety (167.84 mg/g) and lower in Büzgülü variety (97.56 mg/g), the chlorogenic acid content was significantly (p < .05) high in Marcaş variety (296.51 mg/g) and low in Hönüsü variety (153.19 mg/g).The analysis of minerals content showed that Fe, P, Zn, and K were major minerals of the varieties. The analysis of fatty acids showed that the dominant fatty acids in varieties were linoleic, oleic, and palmitic acid.

不同葡萄品种果渣粉的化学组成，生物活性成分，矿物质含量和脂肪酸组成

在本研究中，研究了来自10个变种的葡萄球果的化学成分，生物活性化合物，矿物质和脂肪酸组成，这些变种具有多个葡萄变种的种子和表皮。品种Ekşikara，Çalkarası和Marcaş表现出显着（p  <.05）较高的总酚含量（分别为127.18、138.41和147.51 mg / 100 g），同时具有较高的抗氧化活性（95.47、96.71和98.47％） ）。酚类化合物的HPLC分析表明，绿原酸，原儿茶素，协同酸和阿魏酸是该品种的主要成分。此外，protocatechin含量显著（p Marcaş品种（167.84 mg / g）较高（<.05），Büzgülü品种（97.56 mg / g）较低，Marcaş品种（296.51 mg / g）的绿原酸含量显着（p  <.05）高Hönüsü品种（153.19 mg / g）中的矿物质含量分析表明，Fe，P，Zn和K是该品种的主要矿物质。脂肪酸分析表明，品种中的主要脂肪酸为亚油酸，油酸和棕榈酸。
