Related: Introduction to Fats. Smoke Point is the temperature at which oil breaks down and burn, giving food an unpleasant burnt taste. In the process, free radicals harmful to your body are released.
Cooking oils have different smoke points. Although olive oil is widely hailed as a healthy and flavourful option, it is not suitable for high-heat cooking. So, for deep-frying from to degrees Celsius and baking at high temperatures, use oils with higher smoke points.
It is good to have different types of oil in your kitchen for different uses such as drizzling on salads, light cooking or deep-frying. Here is a list of the more common cooking oils available and what they are suitable for. Canola Oil — Canola has a high content of unsaturated fats, which makes it a healthier choice. It also contains omega-3 and omega-6 fatty acids. Olive Oil Extra Virgin — Extra virgin olive oil is flavourful and ideal for enhancing the taste of food.
High-quality olive oils tend to be expensive, hence it is better used for drizzling over salads, raw foods or as a flavour enhancer. Peanut Oil — This golden oil is also commonly known as groundnut oil. One of the most important things you'll want to consider when picking out a fat is smoke point. But what is a smoke point, and why does it matter? Ever left oil in a pan over high heat, only to turn around and find it billowing with smoke?
That's because every cooking fat, be it butter, lard, or oil, has a smoke point: a temperature at which it stops shimmering and starts sending out some serious smoke signals. Learning how to interpret those signals is a crucial element of any good cook's vocabulary. To understand how smoke points affect food, we have to look to where our fats come from and how they've been processed.
Traditionally, oils are extracted from nuts and seeds through mechanical crushing and pressing. If bottled immediately thereafter, you've got a cold-pressed raw, or "virgin" oil, which tends to retain its natural flavor and color. Many unrefined oils are packed with minerals, enzymes, and other compounds that don't play well with heat and tend to be especially susceptible to rancidity; these are the oils best-suited to drizzling, dressings, and lower temperature cooking.
To produce an oil with a high smoke point, manufacturers use industrial-level refinement processes like bleaching, filtering, and high-temperature heating to extract and eliminate those extraneous compounds. What you're left with is a neutral-flavored oil with a longer shelf life and a higher smoke point. Clarified butter , or ghee, follows the same basic concept: a process designed to extract more heat-sensitive components—in this case, milk solids—from a fat in order to raise its smoke point.
Now, when it comes to actually cooking with fats, smoking oil isn't always a bad thing —oftentimes, you'll want that wok or skillet ripping hot. But when a flavorful, raw oil or pool of butter starts sending up smoke, you're headed into a danger zone. Sure, smoke is pesky, but that's not why you should be concerned. Refined Oils Naturally refined oils are more thoroughly filtered and strained than unrefined, usually with some additional heat but without harsh or damaging chemicals.
Frequently asked questions Should I heat oil to the smoke point? Which oils are genetically engineered? Oil No heat Low heat Med. If smoking occurs, lower heat to avoid consuming unhealthy, damaged oils.
