Grape seed oil in clear glass vial
|Omega-3 fatty acids||α-Linolenic: 0.1%|
|Omega-6 fatty acids||Linoleic: 69.6%|
|Food energy per 100 g (3.5 oz)||3,700 kJ (880 kcal)|
|Smoke point||216 °C (421 °F)|
|Unsaponifiable||0.3% - 1.6%|
|Peroxide value||2.92 mequiv/kg|
Grape seed oil has a moderately high smoke point of approximately 216 °C (421 °F). Due to its clean, light taste, and high polyunsaturated fat content, it may be used as an ingredient in salad dressings and mayonnaise and as a base for oil infusions of garlic, rosemary, or other herbs or spices. It is widely used in baked goods, pancakes, and waffles. It is sprayed on raisins to help them retain their flavor.
The metabolic energy density of grape seed oil is typical of vegetable oils: approximately 3,700 kJ (880 kcal) per 100 g, or 500 kJ (120 kcal) per 15 ml tablespoon.
Grape seed oil is a preferred cosmetic ingredient for controlling moisture of the skin. Light and thin, grape seed oil leaves a glossy film over skin when used as a carrier oil for essential oils in aromatherapy. It contains more linoleic acid than many other carrier oils.
Potential medicinal benefits
Although grape seeds contain antioxidants and other biologically active compounds, the cold-pressed grape seed oil contains negligible amounts due to their insolubility in lipids. For instance, sufficiently high amounts of resveratrol occur in grape seed for it to be extracted commercially, yet it is almost entirely absent in the grape seed oil.
Potential medicinal complications
The following table lists a typical fatty acid composition of grape seed oil:
|Linoleic acid||ω−6 unsaturated||69.6%|
|Oleic acid||ω−9 unsaturated||15.8%|
| Palmitic acid
| Stearic acid
|Alpha-linolenic acid||ω−3 unsaturated||0.1%|
| Palmitoleic acid
|ω−7 unsaturated||less than 1%|
Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol). Grapeseed oil contains small amounts of vitamin E, but safflower oil, cottonseed oil, or rice bran oil contain greater amounts. Grapeseed oil is high in polyunsaturates and low in saturated fat.
