Greeks used wine in the bread making process, whereas Gauls and Iberians used the foam found atop ale for dough fermentation. To learn more about fermentation in dough, click here. You may have heard someone remark, "this is about as interesting as watching bread rise." Well,
View MoreSCIENCE Fermentation. The bread-making process known as "fermentation" is responsible for the holes and the flavour of bread. In actual fact the holes are bubbles of carbon dioxide produced through the process of respiration. Flavour is from the alcohol and other compounds produced through fermentation. Respiration occurs when oxygen is present (aerobic respiration). The basic chemical ...

View MoreScience of bread making. Bread is the product of baking a mixture of flour, water, salt, yeast and other ingredients. The basic process involves mixing of ingredients until the flour is converted into a stiff paste or dough, followed by baking the dough into a loaf.
View More13/01/2016 Bread-making is a process that seems simple, essentially involving the mixing of just four ingredients. However, there’s a lot more chemistry to it than meets the eye; here we delve into the science to work out what’s going on in your loaf. The process of making bread can be broken down at a very simple level into four steps. First, the ingredients are mixed; the four basic ingredients ...
View MoreThe science of fermentation. 06.19.2015. By Staff. Bakers recognize that stiff doughs (low water content) will take longer to ferment. Likewise, a dough that is made slack (higher ingredient water content) will ferment much faster. This is due to the concentration of soluble solids in the free water of the dough. For example, as the ingredient water increases, causing the dough to become ...

View More11/01/2011 In bread making, we are mostly concerned with the enzyme amylase. The main function of amylase in wheat flour is to break down complex starches into simple sugars. The simple diagram above shows a maltose molecule being separated into two glucose molecules. Without this important process occurring in the dough, fermentation would not occur as yeast requires simple sugars in order to

Porridge was cooked on stone slabs, making crude flat breads that were less prone to spoilage and more easily transported. These advances in bread making laid the groundwork for Egyptian and Greek innovation. Here is an excellent video briefly documenting

View More14/02/2020 Is bread fermentation aerobic or anaerobic? Anaerobic and Aerobic Respiration In the bread-making process, it is the yeast that undergoes cellular respiration. Anaerobic respiration — also known as fermentation — helps produce beer and wine and happens without the presence of oxygen, while aerobic respiration requires oxygen to be present.

View MoreNow this wouldn’t be a good article about the science of bread without discussing the breaking down of the yeast. Some yeast enzymes (chemical eating proteins) break down the long chains of starch into individual glucose molecules whilst other enzymes present in the yeast use the glucose molecules to produce CO2 and ethanol in a process known as Fermentation.
View MoreSince yeast uses glucose to perform alcoholic fermentation and make the bread rise, the flour can be used as its “food” along with sugar. Flour is made up of glutenin and gliadin. When combined with warm water, the glutenin and gliadin turn into gluten. This is important in bread making because it strengthens the bread and provides structure. Carbon Cycle. Making bread also plays a role in ...

View MoreThere are lots of different types of flour used in bread, but the most commonly used in raised bread is wheat flour. This is because wheat flour contains two proteins, glutenin and gliadin, which, when combined with water, form gluten. As you knead the dough, the gluten becomes more and more stretchy. This gum-like substance fills with thousands of gas bubbles as the yeast goes to work during ...
