Grapeseed Oil
Grape oil (also grapeseed oil) is a vegetable oil pressed from the seeds of various varieties of Vitis vinifera grapes, an abundant by-product of wine making. Most grapeseed oil is produced in Italy, with other producing nations including France, Spain, and Switzerland. Although known to Europeans for centuries, grape seed oil was not produced or used on a large scale until the 20th century, largely due to the fact that grape seeds contain a lower percentage of oil as compared to other oil-producing seeds, nuts, or beans.
Grape seed oil is extracted from grape seeds and has a relatively high smoke point, approximately 420 °F (216 °C), so it can be safely used to cook at high temperatures. Grape seed oil can be used for stir-fries, sautéing and fondue. In addition to its high smoking point, grape seed oil has other positive attributes in relation to cooking. It has a clean, light taste that has been described as `nutty`. Because of its `neutral` taste, grape seed oil is often used as an ingredient in salad dressings or as a base for infusing or flavoring with garlic, rosemary, or other herbs or spices. It is also used as an ingredient in homemade mayonnaise.
The metabolic energy density of grape seed oil is comparable to that of other oils: about 120 kcal per tablespoon (34 kJ/ml). However, because less oil is needed for cooking it can be used within low-fat diet, especially when combined with good frying techniques (such as using enough oil, not overcrowding the pan, and having the oil at the correct temperature) which reduce the amount of absorbed oil.
Current medical information
Grape seed oil is reputed to contain plentiful antioxidants, as well as to lower cholesterol levels. In a study presented in 1993 at the American College of Cardiology Scientific Session, Nash and colleagues showed in 56 men and women using up to 1.5 ounces (43 g) per day, an amount that one can cook with, that grape seed oil raised HDL levels by 13% and reduced LDL levels by 7% in three weeks. The total cholesterol/HDL ratio fell 15.6%, and the total LDL/HDL ratio fell 15.3%, which could be significant for those at risk of heart attack.[citation needed]
Vitamins in grape seed oil
Vitamin E (0.8 to 1.2 g/kg), Vitamin C and Beta-Carotene.
There is unconfirmed information that grape seed oil also contains Vitamin D.
Average composition of Grape Seed Oil fatty acids
Common Name Acid Name Average Percentage Range
Omega-6 Linoleic acid 69 to 78%
Omega-9 Oleic acid 15 to 20%
Palmitic acid Hexadecanoic acid 5 to 11%
Stearic acid Octadecanoic acid 3 to 6%
Omega-3 A-Linolenic Acid 0.3 to 1%
Palmitoleic acid 9-Hexadecenoic acid 0.5 to 0.70%
Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols
(tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol).
Oligomeric proanthocyanidins
Some sources claim that grape seed oil is also high in procyanidolic oligomers (also known as oligomeric proanthocyanidins, OPCs or PCOs). However other sources dispute this. Because proanthocyanidins are polar molecules which are insoluble in nonpolar liquids such as oils, grape seed oil is unlikely to contain as much PCO as other grape products like fresh grapes, grape juice or red wine. Some published independent analyses show that grape seed oil typically contains almost no PCO at all . It has been claimed that many distributors of pycnogenol and related products are involved in pyramid schemes. This in no way impacts its possible health benefits, of course.
