Linseed oil is not generally recommended for use in cooking. In one study, the content of alpha -linolenic acid (ALA) in whole flaxseeds did not decrease after heating the seeds to temperatures of up to 178 °C (352.4 °F) for one and a half hours.
What is linseed oil?
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum). The oil is obtained by pressing, sometimes followed by solvent extraction.
Is linseed oil alkali refined?
Linseed oil dries relatively fast and produces a durable, flexible paint film. The term alkali refined, when used in relation to oils, refers to the way the oil is extracted from the seed and subsequently clarified. This article will describe the alkali refining process and how it produces a high quality oil for use in artist paints and mediums.
How is linseed oil produced?
The nutritional values are expressed as percent (%) by mass of total fat. Stand oil is generated by heating linseed oil near 300 °C for a few days in the complete absence of air. Under these conditions, the polyunsaturated fatty esters convert to conjugated dienes, which then undergo Diels-Alder reactions, leading to crosslinking.
