Abstract:
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.
