What is the function of frying?

Through frying, one can sear or even carbonize the surface of foods while caramelizing sugars. The food is cooked much more quickly and has a characteristic crispness and texture. Depending on the food, the fat will penetrate it to varying degrees, contributing richness, lubricity, its own flavour, and calories.

Why does fried food shrink?

It is defined as change in volume caused by moisture loss, reduction of pores, protein denaturation and the likes that occur during food processing such as frying. Most foods, because of high initial moisture content, will undergo considerable shrinkage during frying.

Is frying dehydrated?

Frying is probably the most dynamic food process of all. Food is immersed in hot oil and comes out as a totally different product. The frying process is considered a dehydration operation. Moisture is removed from the food being fried, whether that food is a French fry, potato chip or piece of chicken.

Why does oil fry and not water?

Reason: We fry stuff in oil because oil has much higher boiling point in comparison to water. So after heating when oil reaches temperatures greater than the boiling point of water (100 C) it instantly vaporize the water present in food into steam.

What are the advantages of frying?

Because oil heats to a higher temperature than water, frying is faster than boiling, and fried surfaces, rather than becoming soft as they do when boiled, broiled, or steamed, coagulate. The resulting fried food is incomparably tasty, crisp, and beautiful.

Why should water be kept away from the deep fryer?

Water is a very dangerous liquid when deep frying. When water encounters very hot oil (about 350 °F) water vaporizes instantaneously turning into super heated steam. It expands quickly, which can cause oil to splatter and risk bodily injury.

What happen to oil during frying?

The hydrolysis, oxidation, and polymerization of oil are common chemical reactions in frying oil and produce volatile or nonvolatile compounds. Most of volatile compounds evaporate in the atmosphere with steam and the remaining volatile compounds in oil undergo further chemical reactions or are absorbed in fried foods.

What happens when food is deep fried?

When food is added to hot oil (usually 350°F to 375°F), its surface dehydrates. Meanwhile, through a series of Maillard reactions (named after the chemist Louis Camille Maillard), its sugars and proteins break down to create complex flavor and golden-brown color.

Why does oil fry but water boils?

Boiling in water doesn’t really change that because everything is already surrounded in water, but frying in oil is hot enough to boil the water inside the food, so in addition to the Maillard reaction, deep frying tends to dehydrate food.

Can you fry without oil?

In the pan: You can easily fry meat with no cooking oil in a griddle or a normal, nonstick pan. The natural fats of the meat are enough to cook it, but if you want to add a little something to help it on its way, try a splash of sparkling mineral water.
