Industry building bread from rye flour and from a mixture of different varieties of flour

Rye flour, from ground rye kernels, is used to produce rye bread as well as sourdough. Rye flour is the powder milled from whole rye berries or grains from rye grass. It is used to produce rye and sourdough bread, providing a distinctive flavor and improved nutritional content compared to bread baked with wheat flour. Rye is very prevalent in Europe, and is still to this day the most popular flour used in Germany.

VIDEO ON THE TOPIC: Science: What is Gluten? Here's How to See and Feel Gluten

I would like to acknowledge that the material presented here is the work of Willie Prejean, a retired professional baker. Wheat flour is essential because it is milled from the only cereal grain known to contain the proteins glutenin and gliadin which when combined with water form gluten, the elastic material which holds the gas produced by the chemical reaction of the yeast enzymes on sugar. As in building a house, the framemust be built.

Gluten forms the framework of bread and also thecell structure of the interior of the loaf. Rye flour contains both glutenin and gliadin but is incapable of forming gluten because there are substances in rye flour that interferes with it's ability to form gluten.

That is the reason why wheat flour must be included as a large percentage of the flour in rye bread formulas. How to separate the gluten from wheat flour. First you must wash out all the starches from a mixture of flour and water as follows:. Mix a small amount of flour about 8 ounces with just enough water to form a stiff ball of dough. Soak the ball of dough in water for about 30 minutes.

Over a fine mesh sieve, and under running water from a faucet, wash out all the starch. When all the starch has been removed the water will run clear. Warning, if you try to wash gluten from soft wheat flour cake flour , you will be able to get only a tiny bit of gluten from it. Hard wheat flour bread flour will yield a large amount of gluten. Rye flour will yield zero amount of gluten. If you bake the ball of wet gluten at about degrees F.

Once you have washed out the starches, you end up with raw wet gluten. If you soak the ball of gluten in pure ethyl alcohol, the glutenin and the gliadin will separate out. The gliadin is the sticky part and will form long tiny silky looking strands when touched with the finger.

The glutenin on the other hand will look and feel like tough raw rubber. Hard spring wheat and hard winter wheat are the best types of wheat for producing quality breads.

Spring wheats are grown in the Northwest where there is less rainfall than in other wheat growing areas. Thisresults in a higher percentage of protein and a lower percentageof starch than wheats grown in the Southwest where more rain falls. Hard spring wheat generally produce loaves with greater volumethan winter wheats, but with slightly more open crumb texture.

Millers combine the two types of wheat in their blend to improve interior loaf characteristics. Hard White Wheat grown in some Western States, is also used in bread production. It is slightly lower in protein than spring and winter wheats. Duram Wheats which contain a higher percentage of proteins than does most other types of wheats are used primarily in making spaghetti and macaroni products.

Milling of wheat into flour. Basically, after the wheat has been cleaned and tempered, and the percentage of moisture within the grain has been adjusted, the wheat passes through several reduction rollers.

The grounded middlings are separated into several streams of flour by sieving and bolting. The bran particles which have been removed are used in cereals. Some are also used for animal feed. Grades of flour. Whole wheat flour is flour produced from percent of the wheat.

Straight grade of flour. This is all of the flour. Straight flour is similar to all purpose flour found in grocer stores. Patent flour is a highly refined flour which remains after all the clear flours have been removed.

Patent flours are produced from the inner-most part of the wheat where the best quality proteins are located. Clear flour is the portion of the flour remaining after the patent flour streams have been separated.

Clear flour generally contain a higher percentage of protein than the other grades, but thequality of the protein is lower. This type pf flour is generally used to produce French bread. It is also mixed with wheat flour and rye flour by the baker to produce loaves with greater volume. Flour bleaching and maturing. In order to produce qualitybreads from fresh milled flour it must be allowed to age or mature in storage for about a month. Bleaching and maturing agents are used to artifically age and whiten the flour.

This results in flour that can be used immediately after milling to produce aquality product. Strength of flour is its ability to be made into well piled loaves. The flour should have a high content of quality protein to retain gas and contain enough natural sugars and diastatic enzymes to produce enough sugar from the starch for uniform gas production.

Tolerance is the ability to produce a quality product for some time after the optimum fermentation time has elapsed and in the event that the dough was overmixed.

Enrichment of flour is the process of replacing the vitamins and minerals removed during the milling process. Most of the vitamins and minerals are located in the outer portions of the wheat, and since most of the outer portions of the wheat are not used to produce the best grades of flour, these essential elements must be replaced. The exception is whole wheat flour. Enzymes in flour. The two most important enzymes in flour are protease and diastase.

Protease conditions the gluten, improving its elasticity and its ability to retain the gas produced during fermentation.

Diastase changes some of the starch in flour to dextrins and maltose sugar. Some flours do not contain a sufficient amount of diastase enzyme due to poor climatic conditions underwhich the wheat was grown. Sprouted wheat can be added to the flour by the miller or the baker can add a specially prepared diastatic malt in his formula.

Rye flour is a finely ground flour prepared from the rye grain. It contains about the same amount of protein as wheat flour.

However, the flour contains gummy substances which prevent formation of gluten, accounting for the small compact loaves of bread made from a dough containing only rye flour. To produce rye breadwith acceptable volume, not more than 20 percent dark rye flour, 30 percent medium rye flour, and 40 percent light rye flour canbe used in the formula. White bread flour must be used in theformula so enough gluten can be formed to hold the gas during fermentation, and to form the structure of the texture.

Water is a basic ingredient in bread baking. It would be impossible to produce a loaf of bread without water in some form. There are several types of water. Hard water produces better quality bread than any type of water. Soft water weekens the gluten during mixing and fermentation. This can be corrected to some degree by increasing the percentage of salt in the formula slightly and by using mineral yeast food in the formula.

Alkaline water is the most harmful, because it doesn't only weaken the gluten, but retards fermentation. Yeast likes a slightly acid medium to perform at its best.

The weakening of the gluten and retarding effect on yeast can be corrected by using an acid ingredient such as vinegar acedic acid or lactic acid. Special types of mineral yeast food has been developed to correct this problem. Yeast is one of the essential ingredients in bread production. It is a one cell plant which multiplies by a process known as budding. Under the right conditions of water, sugars, warmth,and dissolved minerals, yeast causes fermentation.

Yeast is available in compressed form which must be kept under refrigeration until it is ready to be used and active dry yeast which need not be refrigerated. Active dry yeast has an extended shelf life. Both will generally produce satisfactory results.

However, a majority of large Commercial Bread Bakeries use compressed yeast in their formulas. When using active dry yeast half as much active dry yeast is required as compared with compressed yeast. Enzymes in yeast consist of invertase, maltase, zymaseand protease. There are others, but they are not important in bread production. The protease enzyme in yeast is only activeif the cell wall of the yeast is damaged in some way. That is the only time it can penetrate the cell wall of the yeast.

There are always a few damaged yeast cells especially in dry yeast where some cells are damaged during the drying process, or in yeast that has gotten a little old. If the protease enzyme does penetrate the cell wall of the yeast, it will weaken the gluten.

Invertase enzyme is an entercelluar enzyme. Sucrose, cane or beet sugar when dissolved enter the cell wall and are changed to dextrose and fructose, which are later changed by the enzyme zymase below. Maltase attacks malt sugar. The malt sugar is changed to two molecules of the simple sugars dextrose. Zymase is the enzyme which changes the simple sugars, dextrose and fructose into carbon dioxide gas and alcohol, and several esters which result in producing the unique aroma flavor and taste of breads.

Also, the gas produced causes the dough to rise.. Fermentation will be discussed in more detail in a later paragraph on bread production procedures.

Salt is another essential ingredient in quality bread production. It has several functions. It regulates fermentation.

Flour forms the foundation for bread, cakes, and pastries. It may be described as the skeleton, which supports the other ingredients in a baked product. This applies to both yeast and chemically leavened products.

Flour Power: Your Definitive Guide to Baking With White, Wheat, and More

The course provides knowledge of and insight into the hygienic design of equipment and Rye bread is a regular bread type. It is baked of dough from broken or grinded rye. It used to be eaten as daily bread, but wheaten bread is eaten more these days, because of the light structure. Rye bread contains a lot of fibres and iron. The Frisian- and Brabantine rye are concerning ingredients and process so different that they are almost incomparable.

The Best Flour for Baking Bread—and How to Use It

When baking the perfect loaf of bread you usually imagine it with a golden crispy crust on the outside with a soft and airy crumb inside. Therefore, it is especially frustrating when, after a well-intentioned baking process, we remove a loaf of bread from the oven, hard as a brick inside. Why is this happening and how can the result be better? From my experience as a baker it could be the results of one of these factors:. Dense or heavy bread can be the results of : not kneading enough the dough mix. Mixing the salt and yeast together or Losing patience in the middle of molding your bread and there is not enough tension in your finished loaf before baking.

My bread baking journey started with the recipe on the back of the King Arthur whole wheat flour bag.

Wheat, whole-wheat, bleached, gluten-free…when it comes to baking with flour, there are more choices than ever. It's a big, scary world in the field of flour, so we spoke to four experts: baker Alex Bois of Philadelphia's High Street on Market one of our Best New Restaurants! Tie on an apron—we're about to take a deep dive into the flour bin. Wheat's seed head the top of the plant is made from three portions: the germ, the bran, and the endosperm. White flour has been stripped of the bran and germ, leaving behind the fine, pale endosperm. It is more shelf-stable than whole wheat flour, but as a result, has a milder flavor and less nutritive qualities—the bulk of the fiber and protein are contained in the bran and germ. Whole wheat flour is made from grinding all three portions of the seed head. Small-scale millers will often grind the seed head whole , but large, commercial millers frequently separate the portions and then add the bran and germ back in to the endosperm for "Frankensteined" whole wheat flour. Whole wheat flour is more absorbent than white flour, thus requiring more liquid. This results in extra-sticky doughs that can be challenging for beginning bakers to work with.

For more than two decades, this work has remained the leading advanced textbook and easy-to-use reference on food chemistry and technology. Its fourth edition has been extensively re-written and enlarged, now also covering topics such as BSE detection or acrylamide. Food allergies, alcoholic drinks, or phystosterols are now treated more extensively.

Flour is a fine powder made by grinding wheat kernels. It is the main component of foods such as bread, crackers, pasta, tortillas, cakes, cookies and pastries. Among other grains, wheat flour is unique due to its ability to form a gluten network when mixed with water. This property is responsible for the rise in yeasted dough and puff pastry. There are many varieties and types, but a few common kinds are:. The first flour was produced around BCE, by crushing grains between two stones. Archaeological evidence shows the Romans spread baking and wheat milling throughout Europe. New milling technologies were introduced in the late 19th and early 20th centuries. Today, this ingredient is typically made in a roller mill which crushes the individual grain kernels into fractions.

Why Is My Bread So Heavy and Dense as a Brick?

Wheat has accompanied humans since remote times as far back as to BC in their evolution and development, evolving itself in part by nature and in part by manipulation from its primitive form emmer wheat into the presently cultivated species. The more important modern wheat species are hexaploid bread wheat Triticum aestivum L. Except for the very warm tropics, wheat adapts to all diverse climatic conditions prevailing in agricultural lands and, therefore, it is harvested in the world all year around. Its wide adaptation to diverse environmental conditions, along with its unique characteristic of possessing a viscoelastic storage protein complex called gluten, are the main factors making wheat the most important food crop in the world. There are quite large differences in grain composition and processing quality among wheat cultivars within a species. Hence, one cultivar may be suitable to prepare one food type but unsuitable to prepare a different one.

For grain and bakery products that meet one of the standards prescribed in Division 13 of the FDR, the name appearing in bold-face type, but not in italics, in the FDR is the appropriate common name of that product. The common name "biscotti" is used by the general population and can be used on its own without further explanation.

Flour is a powder made by grinding raw grains , roots , beans , nuts , or seeds. It is used to make many different foods. Cereal flour is the main ingredient of bread , which is a staple food for most cultures.

In , committed locavore Mai Nguyen experienced a hard winter for the first time. A Californian temporarily living in Canada, Nguyen scoured nearby markets for a local, seasonal treat to break up the monotony of cabbage and potatoes. In the midst of winter, I was so grateful to experience these distinctive, complex flavors. I never knew grain could be so diverse!

In this comprehensive guide, Rose Levy Beranbaum , author of numerous books on baking, including The Bread Bible , teaches us how to make show-stopping loaves of bread from start to finish. In the first section, she covers the basics of measuring, kneading, and proofing , plus shaping , and decorating and baking the final loaves. Basic bread contains very few ingredients—often just flour, water, yeast, and salt, plus sometimes oil or butter, eggs, seeds, grains, and nuts. With so few ingredients, it's very important to use the best quality and to store them properly.
