The Chopin Alveograph is a tool for flour quality measurement. [1] It measures the flexibility of the dough produced from the flour, by inflating a bubble in a thin sheet of the dough until it bursts. The resulting values show the strength of the flour, and thus its suitability for different uses.
It was developed in 1920 in France by Marcel Chopin, who named it the Extensimeter. [2]
Developed in the late 1920s in France by Marcel Chopin, the Chopin Alveograph is used in bakery worldwide. The alveographic test enables to measure the tenacity (resilience), the extensibility, and elasticity of a dough (standardized mix of flour and water). This measurement of the strength of flours is considered as a good index of the baking quality of baking flours.
In France it has been used in regulations since at least 1963 as a criterion in milling for the composition of flours destined to the "french" type bread-baking. [3]
Agronomist Norman Borlaug (Nobel Prize in 1970) used this invention to select varieties of wheat for tropical environments.[ citation needed ]
The Chopin alveograph is composed of two inseparable elements:
Still used nowadays, the Chopin alveograph is manufactured by Chopin Technologies, subsidiary of the KPM Analytics company. They produce a derivative device called the Mixolab which, among other uses, measures the degree of degradation due to pest and fungus, and the protection provided by insecticides and fungicides.

Bread is a staple food prepared from a dough of flour and water, usually by baking. Throughout recorded history and around the world, it has been an important part of many cultures' diets. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture.
Pastry refers to a variety of doughs, as well as the sweet and savoury baked goods made from them. These goods are often called pastries as a synecdoche, and the dough may be accordingly called pastry dough for clarity. Sweetened pastries are often described as bakers' confectionery. Common pastry dishes include pies, tarts, quiches, croissants, and pasties.
In cooking, a leavening agent or raising agent, also called a leaven or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action that lightens and softens the mixture. An alternative or supplement to leavening agents is mechanical action by which air is incorporated. Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen.
A baker is a tradesperson who bakes and sometimes sells breads and other products made of flour by using an oven or other concentrated heat source. The place where a baker works is called a bakery.
A baguette is a long, thin type of bread of French origin that is commonly made from basic lean dough. It is distinguishable by its length and crisp crust.
Dough is a malleable, sometimes elastic paste made from grains or from leguminous or chestnut crops. Dough is typically made by mixing flour with a small amount of water or other liquid and sometimes includes yeast or other leavening agents, as well as ingredients such as fats or flavourings.
Soda bread is a variety of quick bread made in many cuisines in which sodium bicarbonate is used as a leavening agent instead of yeast. The basic ingredients of soda bread are flour, baking soda, salt, and buttermilk. The buttermilk contains lactic acid, which reacts with the baking soda to form bubbles of carbon dioxide. Other ingredients can be added, such as butter, egg, raisins, or nuts. Quick breads can be prepared quickly and reliably, without requiring the time and labor needed for kneaded yeast breads.
Crispbread is a flat and dry type of bread, containing mostly rye flour. Crispbreads are lightweight and keep fresh for a very long time due to their lack of water. Crispbread is a staple food and was for a long time considered a poor man's diet.
A bread making machine or breadmaker or Bread Maker is a home appliance for baking bread. It consists of a bread pan, at the bottom of which are one or more built-in paddles, mounted in the center of a small special-purpose oven. The machine is usually controlled by a built-in computer using settings input via a control panel. Most bread machines have different cycles for different kinds of dough—including white bread, whole grain, European-style, and dough-only. Many also have a timer to allow the bread machine to function without operator input, and some high-end models allow the user to program a custom cycle.
The Chorleywood bread process (CBP) is a method of efficient dough production to make yeasted bread quickly, producing a soft, fluffy loaf. Compared to traditional bread-making processes, CBP uses more yeast, added fats, chemicals, and high-speed mixing to allow the dough to be made with lower-protein wheat, and produces bread in a shorter time. It was developed by Bill Collins, George Elton and Norman Chamberlain of the British Baking Industries Research Association at Chorleywood in 1961. As of 2009, 80% of bread made in the United Kingdom used the process.
Vienna bread is a type of bread that is produced from a process developed in Vienna, Austria, in the 19th century. The Vienna process used high milling of Hungarian grain, and cereal press-yeast for leavening.
The sponge and dough method is a two-step bread making process: in the first step a sponge is made and allowed to ferment for a period of time, and in the second step the sponge is added to the final dough's ingredients, creating the total formula. In this usage, synonyms for sponge are yeast starter or yeast pre-ferment. In French baking the sponge and dough method is known as levain-levure. The method is reminiscent of the sourdough or levain methods; however, the sponge is made from all fresh ingredients prior to being used in the final dough.
A dough conditioner, flour treatment agent, improving agent or bread improver is any ingredient or chemical added to bread dough to strengthen its texture or otherwise improve it in some way. Dough conditioners may include enzymes, yeast nutrients, mineral salts, oxidants and reductants, bleaching agents and emulsifiers. They are food additives combined with flour to improve baking functionality. Flour treatment agents are used to increase the speed of dough rising and to improve the strength and workability of the dough.
In Judaism, the dough offering is an assertive command requiring the owner of bread dough to give a part of the kneaded dough to a kohen. The obligation to separate the dough offering from the dough begins the moment the dough is kneaded, but may also be separated after the loaves are baked. This commandment is one of the twenty-four kohanic gifts, and, by a biblical injunction, is only obligatory in the Land of Israel, but from a rabbinic injunction applies also to breadstuffs made outside the Land of Israel.
No-knead bread is a method of bread baking that uses a very long fermentation (rising) time instead of kneading to form the gluten strands that give the bread its texture. It is characterized by a low yeast content and a very wet dough.
Mexican breads and other baked goods are the result of centuries of experimentation and the blending of influence from various European baking traditions. Wheat, and bread baked from it, was introduced by the Spanish at the time of the Conquest. The French influence in Mexican Bread is the strongest. From the bolillo evolving from a French baguette to the concha branching out from a French brioche even the terminology comes from France. A baño maría, meaning a water bath for a custard type budín or bread pudding comes from the French word bain marie. While the consumption of wheat has never surpassed that of corn in the country, wheat is still a staple food and an important part of everyday and special rituals. While Mexico has adopted various bread styles from Europe and the United States, most of the hundreds of varieties of breads made in the country were developed here. However, there is little to no baking done in Mexican homes; instead, Mexicans have bought their baked goods from bakeries since the colonial period.
Straight dough is a single-mix process of making bread. The dough is made from all fresh ingredients, and they are all placed together and combined in one kneading or mixing session. After mixing, a bulk fermentation rest of about 1 hour or longer occurs before division. It is also called the direct dough method.
Manitoba flour, a name chiefly used in Italy, is a flour of common wheat originating in the Canadian province of Manitoba. It is a strong flour, and distinguished from weaker flours as measured with a Chopin alveograph.
Palianytsia is a type of Ukrainian hearth-baked bread, made mostly of wheat flour in a home oven. The yeast hearth bread has a semi-circular cut across the top third of the loaf.
