The Chemistry of Fried Food

You know it, and you love it. Fried food! But there’s more to fried dishes than just plopping food into hot oil. You have to know what’s up with the food you’re cooking and what oils will work best for you dish.

There are absolutely no links between butter (saturated fats) and heart attacks. If you can show me a single, clinical, scientific study that concludes otherwise, I'll take it back. But, since there aren't any clinical studies linking saturated fats to cardio-vascular disease, I won't have to. Good luck.

RockCandii How is that not serious? Boiling points, heat transfer, and movement are all physical properties. Cooking something is a chemical change, but they just talked about the heat transfer and moisture evaporation here. They could have brought in what different organic compounds made what kinds of oils, or how those isomers affected their properties like boiling point, but this was just entirely "Heat transfers, water boils, oil takes its place".

@stephanzielinski7922 7 жыл бұрын

You can't meaningfully say "twice the temperature" when using Celsius. You have to look at it in Kevin. (Or Rankine, but that's uncommon.) The boiling point of water is around 100C, or 373K. 180C is 453K. Thus, oil that hot is about 21% hotter than the boiling point of water.

Don't forget that also higher temperatures reduce oil uptake. Never drop food into a cold fryer. The boiling water on the surface creates a pressure that pushes oil away and resists the uptake. If the oil isn't hot enough, it not only takes longer to cook but there's no vapor pressure to hold back the oil from getting into the food.

As a fry cook, this is kind of interesting. It's so weird how the smallest bit of water can cause the oil to start bubbling and crackling like crazy. Tip: Flour helps a looot with oil. At my job, you have to lay the chicken horizontally into the grease, so hot oil will typically get splashed right onto you. If it happens, all we do is rub a little flour onto the spot immediately and it's like it never happened.

*Positive:* This is an informative video: Like the bubbles being caused by moisture evaporating off. Neat fact! *Negative:* "Since the Oil's temperature is nearly 2 times the boiling point of water" Not really: Celsius isn't an absolute scale, Kelvin is. Water boils at around 373.15K Fat at 180C is at around 453.15K, which isn't double water's boiling point (Just as I wouldn't say -10C is twice as cold as -5C, from an energy point of view) *Question:* Yes, the air bubbles could form a protective layer around the fried food like the Leidenfrost effect, but if the oil, or even the air from the food, is hot and is touching the solid food directly, isn't that conduction, not convection? I believed convection was the movement of fluid or even other materials due to hotter (less dense) and colder (more dense) areas. Yes, they do rise to the top, so yes the food is in a hotter area, but that's not what's directly cooking the food, right?

@GKMcWhite 7 жыл бұрын

They say conduction, where do they say convection?

@Firestar174 7 жыл бұрын

Hey Dittoma! Food scientist here from the University of Illinois - First, you should realize that in Food Chemistry it is very common to use *C rather than Kelvin. Mainly, this comes from a standpoint of using repeatable and the ubiquitous temperature. So while it isn't an absolute scale, they are just doing 180/100*C, or the degrees of frying divided by water boiling in Celsius. She wouldn't be incorrect if she said "double the boiling point in degrees Celsius", technically. Furthermore, to answer your question: The mechanism of frying is a complex one. As heat penetrates, water inside the material turns to vapors and then diffuses out of the material. As this occurs, oil penetrates into the first little bit of layer around the food. With this opened parting, heat penetrates through the hot oil inside and through the surrounding hot oil. Thus, convection spreads the liquid, aka oil in this case, to spread heat. However, according to Dr. Pawan Tahkar, a very seasoned researcher in oil mechanics: "Heat penetrates by conduction and convection, water changes to vapor, a pressure gradient is formed, water moves ouwards, and oil brings in large amount of heat causing more water loss." So while they aren't fully correct, they aren't fully wrong! Hope this helps!

Good timing, I just learned how to deep fry stuff two days ago. I've made meat croquettes and deep fried salmon so far. Yummy. I might try potato wedges tonight.

You guys should do a video on the different ways to cook a turkey. Especially frying a turkey and why it can cause a fire. It seems interesting and fitting for a thanksgiving video. You can teach how to fry a turkey properly and SAFELY.

David Yoon, no. 100C = 373.15K. 373.15K *2 = 746.3K. You can't multiple any other temperature scale except for kelvin because it is the only one that is based around absolute zero. Other temperature scales use an offset making multiplication completely arbitrary. "twice as hot" really means the molecules are moving twice as fast. So it must be based on absolute zero or that makes no sense.

verdatum Spot on, man. It is a science show, is it not? Then why on earth would anyone even argue this point? It is clearly only valid to multiply in the Kelvin scale.

As a organic chemist, I've found that the worst episode of this normally good show, ever! Pyrazines muthafuckers! When the magic in the flavor of fried food is in the volatile nitrogenated (normally derived from proteins) in the food! In the presented model fried food is good just because is just grease enough plus fluffynes from popped bubbles generated from the hot oil! It's like to say that the smell of popcorn was already inside the corn grain, and the heat just released them! Or that bread is just flour dried-by-the-heat! There are very fast and complicated organic reations that goes on when starch plus protein are heated (Maillard reactions to protein pyrolisys). PS:Anti glare lens - just google it

In this case I think we are free to interpret "I don't get" as shorthand for "I am exasperated by humanity to the point where I can't articulate it save by expressions of confusion". It's a phrase I've often used myself, also someone with AS. P.S.: I'd ask you kindly not to use the diagnosis as an excuse to be a smartass. q:
