Flour Bleaching Agent
Flour bleaching agent is the agent added to fresh milled grains to whiten the flour by removing the yellow colour pigment called xanthophyll. It whitens the flour, which is used in the baking industry. Overview Usual flour bleaching agents are: *Organic peroxides (benzoyl peroxide) *Calcium peroxide *Chlorine *Chlorine dioxide *Azodicarbonamide *Nitrogen dioxide *Atmospheric oxygen, used during natural aging of flour Use of chlorine, bromates, and peroxides is not allowed in the European Union. Bleached flour improves the structure-forming capacity, allowing the use of dough formulas with lower proportions of flour and higher proportions of sugar . In biscuit making, use of chlorinated flour reduces the spread of the dough, and provides a "tighter" surface. The changes of functional properties of the flour proteins are likely to be caused by their oxidation. In countries where bleached flour is prohibited, microwaving plain flour produces similar chemical changes to the bleaching ...

Bleach
Bleach is the generic name for any chemical product that is used industrially or domestically to remove color (whitening) from a fabric or fiber or to clean or to remove stains in a process called bleaching. It often refers specifically, to a dilute solution of sodium hypochlorite, also called "liquid bleach". Many bleaches have broad spectrum bactericidal properties, making them useful for disinfecting and sterilizing. They are used in swimming pool sanitation to control bacteria, viruses, and algae, and in many places where sterile conditions are required. They are also used in many industrial processes, notably in the bleaching of wood pulp. Bleaches also have other minor uses like removing mildew, killing weeds, and increasing the longevity of cut flowers. Bleaches work by reacting with many colored organic compounds, such as natural pigments, and turning them into colorless ones. While most bleaches are oxidizing agents (chemicals that can remove electrons from other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheat Flour
Wheat flour is a powder made from the grinding of wheat used for human consumption. Wheat varieties are called "soft" or "weak" if gluten content is low, and are called "hard" or "strong" if they have high gluten content. Hard flour, or ''bread flour'', is high in gluten, with 12% to 14% gluten content, and its dough has elastic toughness that holds its shape well once baked. Soft flour is comparatively low in gluten and thus results in a loaf with a finer, crumbly texture. Soft flour is usually divided into cake flour, which is the lowest in gluten, and pastry flour, which has slightly more gluten than cake flour. In terms of the parts of the grain (the grass fruit) used in flour—the endosperm or protein/starchy part, the germ or protein/fat/vitamin-rich part, and the bran or fiber part—there are three general types of flour. White flour is made from the endosperm only. Brown flour includes some of the grain's germ and bran, while whole grain or ''wholemeal flour'' is made ...

Maida Flour
is a white flour from the Indian subcontinent, made from wheat. Finely milled without any bran, refined, and bleached, it closely resembles cake flour. is used extensively for making fast foods, baked goods such as pastries, bread, several varieties of sweets, and traditional flatbreads. Owing to this wide variety of uses, it is sometimes labeled and marketed as "all-purpose flour", though it is different from all-purpose flour. Production is made from the endosperm: the starchy white part of the grain. The bran is separated from the germ and endosperm which is then refined by passing through a sieve of 80 mesh per inch (31 mesh per centimeter). Although naturally yellowish due to pigments present in wheat, is typically bleached, either naturally due to atmospheric oxygen, or with any of a number of flour bleaching agents. While it is milled from winter wheat that has a high gluten content, heat generated during the milling process results in denaturing of the protein, limi ...

Graham Flour
Graham flour is a type of coarse-ground flour of whole wheat named after Sylvester Graham. It is similar to conventional whole-wheat flour in that both are made from the whole grain, but graham flour is ground more coarsely. It is not sifted ("Bolted") with a flour dresser after milling. A report from 1913 claimed that bread made from graham flour had a protein content of 12.1% – only slightly less than white wheat flour and essentially the same as whole wheat flour. Sources Graham flour is available at health food stores, some grocery stores, bakery supply stores, and some specialty and gourmet food shops, or directly from a flour mill that has experience making it. A substitute for it would be a mix of unbleached white flour and wheat middlings; this was a common substitute prior to and after the passage of the Pure Food and Drug Act in 1906, but the FDA gradually established standards and eliminated imitations from the market. History Graham flour is named after Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flour Treatment Agent
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. While they are an important component of modern factory baking, some small-scale bakers reject them in favour of longer fermentation periods that produce greater depth of flavour. These agents are often sold as mixtures in a soy flour base, as only small amounts are required. Examples Examples of dough conditioners include ascorbic acid, distilled monoglycerides, citrate ester of monoglycerides, diglycerides, ammonium chloride, enzymes, diacetyl tartaric acid e ...

Chorleywood Bread Process
The Chorleywood bread process (CBP) is a method of efficient dough production to make bread quickly, producing a soft, fluffy loaf. It was developed by Bill Collins, George Elton and Norman Chamberlain of the British Baking Industries Research Association at Chorleywood in 1961. , 80% of bread made in the United Kingdom used the process. Compared to the older bulk fermentation process, the CBP is able to use lower-protein wheat, and produces bread in a shorter time. For millennia, bread had been made from wheat flour by manually kneading dough with a raising agent (typically yeast) leaving it to ferment prior to baking. In 1862 a radically new and much cheaper industrial-scale process was developed by John Dauglish, using water with dissolved carbon dioxide instead of yeast, with no need for an eight-hour fermentation. Dauglish's method, used by the Aerated Bread Company that he set up, dominated commercial bread baking for a century until the Chorleywood process was developed. S ...

Microwave Oven
A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high-water-content food item. The development of the cavity magnetron in the UK made possible the production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was introduced by Tappan in 1955, but it was still too large and expensive for general home use. Sharp Corpo ...

Oxidation
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogenation, C=C (and other) bonds ar ...

Protein (nutrient)
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein–energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biscuit
A biscuit is a flour-based baked and shaped food product. In most countries biscuits are typically hard, flat, and unleavened. They are usually sweet and may be made with sugar, chocolate, icing, jam, ginger, or cinnamon. They can also be savoury, similar to crackers. Types of biscuit include sandwich biscuits, digestive biscuits, ginger biscuits, shortbread biscuits, chocolate chip cookies, chocolate-coated marshmallow treats, Anzac biscuits, '' biscotti'', and ''speculaas''. In most of North America, nearly all hard sweet biscuits are called " cookies", while the term " biscuit" is used for a soft, leavened quick bread similar to a less sweet version of a ''scone''. "Biscuit" may also refer to hard flour-based baked animal feed, as with dog biscuit. Variations in meaning * In most of the world outside North America, a biscuit is a small baked product that would be called either a " cookie" or a " cracker" in the United States and sometimes in Canada.

Sugar
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars, and are called oligosaccharides or polysaccharides. Starch is a glucose polymer found in plants, the most abundant source of energy in human food. Some other chemical substances, such as glycerol and sugar alcohols, may have a sweet taste, but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural sources of simple sugars. Suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...
