Grapeseed oil is extracted from the seeds of grapes, typically wine grapes.
Since grape seeds are usually discarded as part of the wine making process, the
extraction and sale of grapeseed oil can be a profitable sideline, as well as an
efficient use of a byproduct. In the twentieth century, grapeseed oil began to
be processed and sold in much higher volume, primarily in the United States and
Europe. Many stores sell pure grapeseed oil for various applications.
Because each seed yields a small amount of oil, grapeseed oil is usually
extracted chemically. The chemical extraction does have an impact on the flavor
of the oil, but it makes grapeseed oil affordable for people who want to
purchase it. The oil is known for being light in color and flavor, with a hint
of nuttiness. It is a polyunsaturated oil, and contains beneficial compounds
such as linoleic acid.
There are two primary uses for grapeseed oil: cosmetics and culinary
applications. When purchasing grapeseed oil to use in food, make sure that it is
clearly marked as food grade. Some cosmetic grapeseed oils are stabilized with
chemicals which could be harmful to consume. Like other oils, grapeseed oil
should be stored in a cool dark place until it is used, unless it has been
heavily stabilized. For people who use it rarely, refrigeration is best.
Although grapeseed oil may congeal slightly, it will go rancid much more slowly
when kept in the fridge.
In foods, grapeseed oil has numerous uses. It has a very high smoking point, so
many people use grapeseed oil to fry foods. It can also be included in dressings
and sauces, and since it emulsifies very well, it does not generally separate
when used to make things like mayonnaise. The flavor is also unobtrusive,
allowing diners to focus on the main component of the dish. Culinary grapeseed
oil can also be flavored with the addition of things like peppers, truffle
shavings, and herbs.
In cosmetics, grapeseed oil is widely used. It is often combined with other oils
to make massage oil, since it glides well on the skin and it also has
moisturizing properties. Grapeseed oil appears to assist with skin repair, as it
has mildly astringent and antiseptic qualities. Some companies use grapeseed oil
as a short term natural preservative in body products, while others integrate it
into moisturizing creams, sunscreen, and an assortment of other products.
