The Maillard reaction is a chemical reaction between amino acids and reducing sugars, so along with the caramelizing sugar, proteins in the cookie begin to brown, producing a rich, nutty, toasted flavour. This is the same reaction that occurs in bread and seared steak.
When sodium bicarbonate (baking soda) heats up, it causes a chemical reaction: 2NaHCO3 ? Na2CO3 + H2O + CO2. The CO2 gas that’s formed makes the “bubbles” in the cookies. NaCl (salt) keeps the bubbles from getting too big by slowing the production of CO2.
Baking cookies involves a complex series of chemical changes — and a couple of physical changes, too. These changes turn your ball of dough into the delicious cookie that you love. The first physical reaction occurs at 92 degrees Fahrenheit. That is the temperature at which the butter starts to melt.
The most important science behind a chocolate chip cookie happens at 310 degrees. The Maillard Reaction takes place when sugar combines with amino acids, which come from protein. Once the sugar and amino acids get together, they form new chemical compounds that produce amazing tastes, smells and textures.
Chemistry During Baking
Carbon dioxide gas and water vapor form the bubbles which make cookies rise. Rising doesn’t just make cookies taller. It also opens up space to keep the cookie from becoming too dense. Salt slows down the decomposition of baking soda, so the bubbles don’t get too big.
What are the chemical reactions in baking?
Chemical Reactions That Occur During Baking
- Protein Bonding. Flour contains two important proteins — glutenin and gliadin.
- Magic Leaveners. Leavening agents — such as yeast, baking powder and baking soda — give baked dough its pillowy lightness.
- Maillard Reactions.
- Flavors of Caramelization.
As you bake a cake, you are producing an endothermic chemical reaction that changes ooey-gooey batter into a fluffy, delicious treat!
The sugar, flour and eggs can no longer be separated. The properties of the materials have changed so it is a chemical change.
Why baking is a chemical reaction?
A chemical change occurs when the molecules that compose two or more substances are rearranged to form a new substance! When you start baking, you have a mixture of ingredients. The flour, egg, sugar, etc. combine together to form a batter.
Baking the cookies is a chemical change, but some of the ingredients may go through a physical change before entering the oven.
The cookie starts to rise as the vapors push through the dough. Eventually, the baking soda or powder starts to break down into carbon dioxide gas, which raise up the cookie farther. All these gases leave little holes in the maturing cookie, which makes it light and flaky.
Physical Change
Shape: The shape of the cookie depends on how well your dough ball is and how much dough you put for that cookie. Phase: Solid after it is bake, changes from a round dough ball to a cookie. Ability to be Cut: Sugary, made with sugar,butter, vanilla, chocolate chips, flour, salt,baking soda and eggs.
Baking soda
When added to dough, baking soda releases a carbon dioxide gas which helps leaven the dough, creating a soft, fluffy cookie.
Is baking a synthesis reaction?
Synthesis is a chemical reaction where two or more substances combine to form one substance. Proteins in flour combine through a synthesis reaction to form gluten. Gluten is an important ingredient which forms to give baked goods their signature structure.
What type of reaction is cooking?
The Maillard reaction is a form of non-enzymatic browning that occurs in foods when proteins and/or amino acids chemically react with carbohydrates of reducing sugars. Applying heat during cooking accelerates and continues this intricate process, which elevates the taste, aromas, and appearance of food.
What is chemical reaction in food?
While foods are processed or cooked at high temperature, a chemical reaction occurs between amino acids and reducing sugars which generate different flavours and brown colour (Figure 1). So it is often used in food industry for giving food different taste, colour, and aroma.

Baking a cake is endothermic chemical reaction. The heat helps produces bubbles in the cake that make it light and fluffy. This occurs to the formula of Na2CO3+H2O+CO2=NaHCO3.
Is baking a cake a single replacement reaction?
When baking is taking place, breaking bonds or forming new ones is not considered. However, it is considered a chemical change because there is no change in molecular form. More specifically, physical and structural changes occur due to combining ingredients with the same molecular state.
What is combustion chemical reaction?
combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
When it comes to heat, there are two types of reactions to consider: exothermic and endothermic. Exothermic reaction releases heat, and by contrast, endothermic reaction absorbs heat. Your uncooked treat is experiencing an endothermic reaction in the oven. As you might know, water evaporates at 100°C, which is 212 °F.
What are three examples of exothermic reactions?
Here are some of the examples of exothermic reactions:

How is baking a science?
Chemistry, as you mix different edible chemicals to create dough or batter, with tiny air bubbles trapped inside. Biology, as the culture of yeast provides carbon dioxide to make your bread rise. And physics, as those trapped gases expand and give the rise to the bakes.
Is making chocolate a chemical or physical change?
Chocolate is a physical change because you can change melted chocolate back into solid chocolate.
The chocolate is not uniformly mixed with the dough. These all indicate that a chocolate chip cookie is a heterogeneous mixture.
A chocolate chip cookie is a good example of a heterogeneous mixture. A mixture is a physical combination of two or more different pieces of matter…. See full answer below.
What does baking powder react with?
How Baking Powder Works. Baking powder contains baking soda (sodium bicarbonate) and a dry acid (cream of tartar or sodium aluminum sulfate). When liquid is added to a baking recipe, these two ingredients react to form bubbles of carbon dioxide gas.
Baking powder simply adds carbon dioxide to the equation, providing a more forceful pressure that encourages a dough to spread up and out. Without the well-developed elasticity of a bread dough, the strands of gluten in cookies would sooner snap than stretch, cracking along the surface.
What does baking soda react with?
When baking soda is used in a recipe, it reacts with acidic ingredients, such as chocolate, sour cream, or honey, to produce the carbon dioxide gas that helps fluffs things up. Baking powder has baking soda and an acid, cream of tartar, which react when they get wet.
What happens during baking?
In general, there are three major stages in the baking process: expansion of the dough, drying of the surface, and crust browning. These can be subdivided into the following stages (in the order of temperature increase): Formation and expansion of gases (oven spring).
