Caramelisation Definition Food
Meat is another food that turns brown when cooked, and this is also due to pyrolysis. The difference, however, is that pyrolysis in meat causes a reaction of amino acids in the protein (known as the Maillard reaction). While in carbohydrates, pyrolysis reacts with sugar, which leads to caramelization.

Caramelization is a chemical process that takes place when sugar is heated to a high temperature. In this process, sugar is broken down into a complex series of chemical reactions. This causes the sugar to gradually take on a brown color, which makes its taste much more complex. This process is often used in cooking to produce richer and more complicated flavors from food. It is also crucial in the production of sweets and is responsible for the taste, texture and appearance of the caramel. Caramelized foods develop a taste that goes beyond the unique sweetness of sugar. When sugar caramelizes, they develop hazelnut, bitterness, roasting and even a little butter creaminess. As luck would have it, these compounds can be isolated and then added to food.
If you see something called “natural flavors” in the list of ingredients, they often are. The low temperature at which fructose begins to break down means that it is the easiest sugar to caramelize, but also that caution should be exercised when working with foods high in different types of sugar. The taste of onions is known to benefit from caramelization. However, the sugar in onions comes in several types, including fructose. To successfully caramelize onions, a cook needs to apply enough heat to start breaking down fructose, but not to the point that other sugars are broken down, as the fructose would overheat and start burning. Another fun fact is that frying obviously produces golden brown colors, although French fries are made by immersion in hot, liquefied fat. How can a liquid be dry? In the case of fat, it is considered dry, because when you fry, the fat is warmer than the boiling point of water. This means that all water in the food (at least in the outer part of it) is boiled, and then caramelization begins. All those bubbles you see when something gets into the fryer are the water in the food boiling.
Caramelizing means cooking a food slowly until it becomes sweet, nutty and brown. You can also caramelize or cook pure sugar until it melts and turns golden brown, sweet and thick. Caramelization or caramelization (see Spelling Differences) is the oxidation of sugar, a process widely used in cooking for the resulting nutty flavor and brown color. Caramelization is a type of non-enzymatic tanning reaction. During the process, volatile chemicals are released that create the characteristic taste of caramel. The reaction consists of removing the water (in the form of steam) and breaking down the sugar. The caramelization reaction depends on the type of sugar. Sucrose and glucose caramelize at 160°C (320°F) and fructose caramelizes at 110°C (230°F). Caramelization is one of the many changes that occur when food is exposed to heat, a process more commonly referred to as “cooking.” Proteins such as meat and eggs become firm and opaque.
Vegetables become colored and soften. Fats liquefy. Starches swell and expand like small sponges. Sugar is the specific purpose of caramelization. Most foods contain a certain amount of one sugar or another. Fructose, sucrose, glucose, and maltose are all common in many different foods, just like other sugars. When these sugars are heated, their chemical structure begins to disintegrate. The specific temperature at which this process occurs varies from sugar to sugar, but most begin to caramelize at 310 degrees Fahrenheit (154 degrees Celsius), although fructose has a much lower caramelization point and begins to disintegrate at 230 degrees Fahrenheit (110 degrees Celsius). Heat has a variety of different effects on food. When used correctly in the cooking process, heat does more than just break down indigestible elements and kill hostile microbes. Adding heat to food triggers many complex chemical reactions. These reactions, including caramelization and the Maillard reaction, create many new organic compounds by breaking down and modifying the molecular structure of food.
Most people find that these compounds have very pleasant flavors. While caramelization is done with natural sugars, adding another sweet substance to everything you cook can help kick things off a bit for foods that are low in sugar or have no sugar content.
