The Chemical Equation For Bread Rising

A Simple Explanation the Difference Between Baking Soda & Baking


Have you ever wondered why bread rises when it’s baked? It’s all thanks to a simple chemical equation that occurs during the baking process. In this article, we’ll explore the science behind bread rising and how you can use this knowledge to make better bread at home.

The Science Behind Bread Rising

Bread rising is the result of a chemical reaction between yeast, sugar, and flour. Yeast is a type of fungus that feeds on sugar and produces carbon dioxide gas as a byproduct. When yeast is added to bread dough, it consumes the sugar in the dough and releases carbon dioxide gas. This gas gets trapped in the dough, causing it to rise.

The Role of Flour

Flour plays a crucial role in the bread rising process. When flour is mixed with water, it forms gluten, a type of protein that gives bread its structure. As the dough rises, the gluten stretches and traps the carbon dioxide gas produced by the yeast. This gives bread its characteristic texture and appearance.

The Importance of Temperature

Temperature also plays a role in bread rising. Yeast works best at temperatures between 75-85°F (24-29°C). If the temperature is too low, the yeast will be sluggish and produce less carbon dioxide gas. If the temperature is too high, the yeast will die and the dough won’t rise at all.

How to Make Better Bread at Home

Now that you understand the science behind bread rising, you can use this knowledge to make better bread at home. Here are a few tips to get you started:

1. Use the Right Amount of Yeast

Too much yeast can cause bread to rise too quickly and result in a coarse texture. Too little yeast can cause the bread to rise too slowly or not at all. Use the amount of yeast called for in the recipe and make sure it’s fresh.

2. Knead the Dough Properly

Kneading the dough helps to develop gluten and trap carbon dioxide gas. Be sure to knead the dough for the recommended amount of time, and don’t over-knead it.

3. Allow the Dough to Rise in a Warm Place

As mentioned earlier, yeast works best at temperatures between 75-85°F (24-29°C). Allow the dough to rise in a warm place, such as a sunny window or a warm oven.

4. Bake the Bread at the Right Temperature

Bread should be baked at a temperature of around 375°F (190°C) for the best results. If the temperature is too low, the bread won’t rise properly. If it’s too high, the bread will burn.


Bread rising is a simple chemical reaction that occurs during the baking process. By understanding the science behind it, you can make better bread at home. Use the tips outlined in this article to create delicious, fluffy bread that’s sure to impress your friends and family.
