Walnuts consist of up to 65% oil. The walnut oil obtained from them is a delicate, sweet, aromatic, and sometimes slightly bitter vegetable oil, which is rich in unsaturated fatty acids. It is mainly used with cold foods because it has a very low smoke point and heating destroys many of the important nutrients. It is used to add a finishing touch to a number of dishes, especially in French cuisine.
General and nutritional information:
From Wikipedia: “Walnut oil is oil extracted from walnuts Juglans regia (Persian walnuts). Each 100 g of oil provides about 63.3 g polyunsaturated fatty acids, 22.8 g monounsaturated fats, and 9.1 g saturated fats. It contains no cholesterol.
Unlike most nuts that are high in monounsaturated fatty acids, walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), although it does contain oleic acid as 13% of total fats.”
Culinary uses:
“Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-colored and delicate in flavor and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan frying, most avoid walnut oil for high temperature cooking; heating tends to reduce the oil's flavor & nutritive value and to produce a slight bitterness. In addition cooking rapidly destroys the oil's antioxidants. Walnut oil is at its most valuable in cold dishes such as salad dressings, where it lends its flavor to best advantage.
Over 99% of walnut oil sold in the USA is produced in California. There are also producers in China, Iran, Mexico, France, Romania, Moldova, Ukraine, Turkey, Australia, New Zealand.
There are two types of walnut oil commercially available: cold pressed and refined. Cold pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller pressed and saturated with solvent to extract the highest percentage of oil available in the nut meat. The solvents are subsequently eliminated by heating the mixture to around 400 °F (200 °C). Both methods produce food grade culinary oils. Walnut oil, like all nut, seed and vegetable oils will undergo rancidification accelerated by heat, light, and oxygen.”
Other uses:
“Walnut oil was one of the most important oils used by Renaissance painters. Its short drying time and lack of yellow tint make it a good oil paint base thinner and brush cleaner.
Some woodworkers favour walnut oil as a finish for implements that will come in contact with food, such as cutting boards and wooden bowls because of its safety. People who mix oil & wax to formulate wood finishes value walnut oil as an ingredient because of the edibility of both ingredients. The oil typically is combined with beeswax in a mixture of 1/3 oil to 2/3 beeswax.”

Detailed Nutritional Information per 100g for this Ingredient
Explanations
The majority of the nutritional information comes from the USDA (US Department of Agriculture). This means that the information for natural products is often incomplete or only given within broader categories, whereas in most cases products made from these have more complete information displayed.
If we take flaxseed, for example, the important essential amino acid ALA (omega-3) is only included in an overarching category whereas for flaxseed oil ALA is listed specifically. In time, we will be able to change this, but it will require a lot of work. An “i” appears behind ingredients that have been adjusted and an explanation appears when you hover over this symbol.
For Erb Muesli, the original calculations resulted in 48 % of the daily requirement of ALA — but with the correction, we see that the muesli actually covers >100 % of the necessary recommendation for the omega-3 fatty acid ALA. Our goal is to eventually be able to compare the nutritional value of our recipes with those that are used in conventional western lifestyles.
