- Walnut oil
Walnut oil is oil extracted from
walnut s.Culinary use
Walnut oil is not used as extensively as other oils in
food preparation due to cost. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although sometimes used for pan frying, most chefs do not use walnut oil for high temperature cooking, as heating can remove some of the oil's flavour and produce a slight bitterness; instead it is used primarily as an ingredient in cold dishes such as salad dressings, where its flavour more easily comes through. In addition, the antioxidants present in the oil are easily destroyed in cooking.

Walnut oil was one of the most important and vital oils used by
Renaissance painters. Its quickness of drying and lack of yellow tint make it a goodoil paint thinner and brush cleaner. However, the paint film it produces is often considered inferior to that oflinseed oil .Commercially, walnut oil has become harder to find; demand is often low, and stock can become rancid if kept improperly. Instead of walnut oil many artists and stores sell
linseed oil ,poppyseed oil , andsafflower oil as replacements.Walnut oil is favoured by some woodworkers as a finish for implements that will come in contact with food, such as cutting boards and wooden bowls.
Walnut oil is a good source of
omega-3 fatty acids which are essential to human nutrition.
