Abstract

Grape seed oil, which is extracted with highly toxic organic solvents that are harmful to human health, is produced from tons of grape pomace waste, generated during winemaking. Sometimes, this waste is used to make compost or is burnt, which causes environmental contamination. The functional qualities, antioxidant capacity (AC), α-tocopherol and total phenolic compounds content (TPC) of Black Borgoña (Vitis labrusca) grape seed oil, extracted by supercritical CO2, were evaluated. The high content of linoleic acid (w-6) and monounsaturated fatty acids contributed to the beneficial effect on the functional quality indices, which were 0.20, 0.23, 11.80 for IA, IT and H:H, respectively. In addition, a POV of 6.23 ± 0.08 milliequivalents of peroxide/kg oil and an anisidine index of 2.70 ± 0.05 indicated a good quality oil. Also, a high concentration of α-tocopherol (9.82 ± 0.02 mg/100 g oil) and a high TPC (114.14 ± 3.24 mg GAE/kg oil) were obtained. This study demonstrated that supercritical CO2 extraction is a suitable method for the delivery of a high-quality grape seed oil.

超临界CO2法提取葡萄籽油的功能及化学性质研究

葡萄籽油是用对人体有害的剧毒有机溶剂提取出来的，它是从酿酒过程中产生的成吨的葡萄渣中提取出来的。有时，这些废物被用来制造堆肥或被焚烧，这会造成环境污染。对超临界CO2萃取的黑Borgoña (Vitis labrusca)葡萄籽油的功能品质、抗氧化能力(AC)、α-生育酚和总酚类化合物含量(TPC)进行了评价。亚油酸(w-6)和单不饱和脂肪酸的高含量对功能品质指标有良好的影响，IA、IT和H:H分别为0.20、0.23、11.80。过氧化氢POV为6.23±0.08毫当量/kg油，茴香胺指数为2.70±0.05为优质油。α-生育酚含量高(9.82±0.02 mg/100 g油)，TPC含量高(114.14±3.24 mg GAE/kg油)。本研究表明，超临界CO2萃取是一种适用于高品质葡萄籽油提取的方法。
