Abstract
To explore the potential of the large amount of grape pomace in wineries of China, oils of three Eurasian grape cultivars (Chardonnay, Merlot and Carbernet Sauvignon) and two Chinese traditional grape cultivars (Vitis amurensis and Vitis davidii), were characterised. The results showed seed oil properties differ for various grape varities. Grape seed oils were demonstrated to be good sources of polyunsaturated fatty acid (PUFA) (63.88-77.12 %), sterols (227.99-338.83 mg/100 g oil) and tocotrienols (320.08-679.24 mg/kg oil). Seed oil of V. amurensis exhibited the highest values of polyunsaturated fatty acid, total tocotrienols, total tocols and DPPH· scavenging capacity. Seed oil of Carbernet Sauvignon had the highest contents of squalene, total sterols, total tocopherols and total phenolics. Principal component analysis five grape cultivars differentiated on the basis of bioactive components content and antioxidant properties.Entities:
