Autooxidation can take place if the fats are exposed to enough light and oxygen. This is where the double bonds of the polyunsaturated fatty acid molecules are attacked by free radicals, which leads to a chain-reaction. If left long enough, the food may develop bad sensory properties. For example, meat develops a 'warmed-over' flavour.

What are fats such as olive oil and sesame oil are produced in plants and are liquid at room temperature?
Monounstatured and polyunsaturated fats are produced by plants and are liquids at room temperature.
What fats such as olive oil and sesame oil are produced in plants and are liquid at room temperature?
Monounstatured and polyunsaturated fats are produced by plants and are liquids at room temperature.
Is polyunsaturated a form of fat?
Polyunsaturated fat, or polyunsaturated fatty acid, are fatty acids in which more than one double bond exists within the representative molecule. From a chemical standpoint, polyunsaturated fats are simply fats that have more than one double-bonded carbon in the molecule. Polyunsaturated fats are typically liquid at room temperature and when chilled.
What fatty acid has room for four or more hydrogen atoms?
Polyunsaturated fats
Fatty acid that has room for 4 or more hydrogen atoms?
Polyunsaturated fats.
What are different types of fat found in foods?
Types of fat: 1. Harmful Dietary Fat: a. Saturated fat b. Trans fat 2. Healthier Dietary Fat a. Monousaturated fat b. Polyunsaturated fat
Fats and oils are examples of what?
Fats are classified as saturated, monounstaturated or polyunstaturated. Saturated fats are solid at room temperature. Animal products --meats, poultry, fish, eggs, dairy products--and solid shortenings are the major sources of saturated fats. Tropical oils such as coconut oil and palm kernal oil are also rish in saturated fats. Polyunsaturated and monounsaturated fates are liquid at room temperature. Polyunsaturated fats are found in vegetable oils such as corn oil, safflower oil, sunflower oil and cottonseed oil. High levels of monounsaturated fats are found in olive oil and canola oil.
What type of triglycerides are solid at room temperature?
Saturated fats and trans-fats are solid at room temperature. Polyunsaturated and monounsaturated fats (oils) are liquid at room temperature. Trans-fats are liquid fats that are treated chemically and thermally to mimic saturated fats, usually in a process called hydrogenation. This process in a nutshell (it's a bit more complicated) injects hydrogen into the oils at high temperature and high pressure producing polymers (plastics) from the hydrocarbon molecules in the oils. Most vegetable shortenings are produced this way, shortenings (solid fats) that are not natural saturated fats are trans-fats.
How do fats differ from oils at room temperature?
Generally oils are liquid and fats are solid at room temperature
Why is butter solid and mustard oil liquid at room temperature?
saturated fats (butter) tend to be solid at room temperature whereas monounsaturated and polyunsaturated fats do not (mustard oil is a mixture of mono- and polyunsaturated fats)
What is characteristic of unsaturated fats?
They are liquid at room temperature.
Are Unsaturated fats solid at room temperature?
No, they are liquid at room temperature.
