The smoke point of fats and oils decreases when they are at least partially split into free fatty acids and glycerol; the glycerol portion decomposes to form acrolein, which is the major source of the smoke evolved from heated fats and oils. A partially hydrolyzed oil therefore smokes at a lower temperature than non-hydrolyzed oil.
The smoke point, also referred to as the burning point, is the temperature at which an oil or fat begins to produce a continuous bluish smoke that becomes clearly visible, dependent upon specific and defined conditions. [1] Smoke point values can vary greatly, depending on factors such as the volume of oil utilized, the size of the container ...
Cooking oil (also known as edible oil) is a plant or animal liquid fat used in frying, baking, and other types of cooking. Oil allows higher cooking temperatures than water, making cooking faster and more flavorful, while likewise distributing heat, reducing burning and uneven cooking. It sometimes imparts its own flavor.
The state record low is −61 °F (−52 °C), recorded at Vanderbilt on February 9, 1934, while the state record high is 112 °F (44 °C), recorded at Mio on July 13, 1936. [1]
Low-temperature cooking is a cooking technique that uses temperatures in the range of about 60 to 90 °C (140 to 194 °F) [1] for a prolonged time to cook food. Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of about 70 °C (158 °F), and using a ...
The widespread sale and use of “gutter oil” – or cooking oil recycled from the gutter, household drains and grease traps – emerged as a major issue in the early 2010s.

The recycling of waste cooking oil (aka restaurant grease, used cooking oil or yellow grease) is a process known as “rendering”. During the rendering process fatty acid is separated from the moisture, the solids and any impurities that are present in the waste cooking oil. The rendering of waste cooking oil produces one usable element and ...
