Caramelization or caramelisation (see spelling differences) is the oxidation of sugar, a process used extensively in cooking for the resulting nutty flavor and brown color.Caramelization is a type of non-enzymatic browning reaction. As the process occurs, volatile chemicals are released producing the characteristic caramel flavor.

As mentioned earlier, different kinds of sugar (i.e., sucrose, fructose, glucose etc.) are carbon-based molecules. Caramelization happens to pure sugar when it is heated to 338 degrees Fahrenheit (170 Degree Celsius).As sugar reaches this temperature, it is broken down into simpler sugars, which then dehydrate and fragment into ketones and aldehydes.

en.wikipedia.org/wiki/Caramelization

Caramelization is the browning of sugar, a process used extensively in cooking for the resulting sweet nutty flavor and brown colour.The brown colours are produced by three groups of polymers: caramelans (C 24 H 36 O 18), caramelens (C 36 H 50 O 25), and caramelins (C 125 H 188 O 80).As the process occurs, volatile chemicals such as diacetyl are released, producing the characteristic caramel ...

Mixing water and sugar is a physical change. A physical change is just a change in the form of the substance, whereas a chemical change is when the substance itself changes chemically.

Heating sugar results in caramelization and is a chemical reaction. A chemical reaction is the process in which one substance is altered and forms a new substance with differing properties. Exposure to heat initially melts the sugar into a syrup. This is the breakdown of the sugar into fructose and glucose, and it is marked by the aroma it creates.

Caramelization is a chemical process that takes place when sugar is heated to a high temperature. In this process, sugar is broken down in a complex series of chemical reactions.This causes the sugar to gradually pick up a brown color and makes its flavor much more complex.

Caramel is a sweet treat used for topping, flavor, and fillings in desserts. It can also be used as a stand alone sweet treat. Caramel is created basically by the heating of sugar. We call this Caramelization. Milton Hershey Started Lancaster Caramel Company after moving to Pennsylvania after his failed candy company in New York City.

Fructose, for instance, caramelizes faster than glucose. Honey, which has more fructose in it than does white table sugar (which is fructose and glucose), will therefore caramelize faster than table sugar. Caramelization generally happens after water is gone from a sugar substance, because water limits the temperature to 100 C (212 F.)

It seems weird though to consider an equilibrium process, like acid dissociation in water, as an ongoing chemical change when there is not net change over time. Chemical change should also include changes in oxidation state that do not lead to changes in bonding - like oxidation of iron(II) to iron (III) via electron transfer.

Caramelization occurs during dry heating and roasting of foods with a high concentration of carbohydrates (sugars). Simply speaking, caramelization is the process of removal of water from a sugar (such as sucrose or glucose) followed by isomerization and polymerisation steps. In reality the caramelization process is a complex series of chemical ...
