摘要
本文报道了葡萄耔油和饼粕的化学组成及特性。经测定,葡萄籽中粗蛋白、脂肪和纤维素的含量分别为8.4%、15.0%和37.2%;葡萄籽油中,不饱和脂肪酸为89.6%,其中亚油酸占72—76%,碘值、皂化值和酸值分别为138.3、191.5和1.68。我们还对重要矿物元素Ca、Mg和K的含量进行了测定。在葡萄酿酒后的下脚料中,葡萄籽占20—26%,对其进行二次深加工,不仅可以减少环境污染,还可以增加社会经济效益。
This paper reports the nutritive value and characteristics of grape seeds oil in which contents of crude proteins,fats and fibers are respectively 8.4%, 15.0% and 37.2%. It is found that grape seeds contain significant elements, such as Ca, Mg and K The content of unsaturated fatty acids is 89.6%, in which the content of predominate linoleic acid is 72—76%. The iodine value, saponification number and acid value of grape seed oil are 138.3, 191.5 and 1.68, respectively. Grape seeds account for 20—26% of the leftovers in wineries. Recovering and using the leftovers not only can decrease the environmental pollution but also increase the social and economic benefit.
