Ammonium Carbonate
Ammonium carbonate is a chemical compound with the chemical formula . It is an ammonium salt of carbonic acid. It is composed of ammonium cations and carbonate anions . Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and is a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and salt of hartshorn, and produces a pungent smell when baked. It comes in the form of a white powder or block, with a molar mass of 96.09 g/mol and a density of 1.50 g/cm3. It is a strong electrolyte. Production Ammonium carbonate is produced by combining carbon dioxide and aqueous ammonia. About 80,000 tons/year were produced as of 1997. : An orthorhombic ammonium carbonate monohydrate is known (). It crystallizes in an ammonia solution exposed in a carbon dioxide-rich atmos ...

Ammonium Bicarbonate
Ammonium bicarbonate is an inorganic compound with formula (NH4)HCO3. The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion. It is a colourless solid that degrades readily to carbon dioxide, water and ammonia. Production Ammonium bicarbonate is produced by combining carbon dioxide and ammonia: : Since ammonium bicarbonate is thermally unstable, the reaction solution is kept cold, which allows the precipitation of the product as white solid. About 100,000 tons were produced in this way in 1997. Ammonia gas passed into a strong aqueous solution of the sesquicarbonate (a 2:1:1 mixture of (NH4)HCO3, (NH4)2CO3, and H2O) converts it into normal ammonium carbonate ((NH4)2CO3), which can be obtained in the crystalline condition from a solution prepared at about 30 °C. This compound on exposure to air gives off ammonia and reverts to ammonium bicarbonate. Salt of hartshorn Compositions containing ammonium carb ...

Molar Mass
In chemistry, the molar mass () (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical substance ( element or compound) is defined as the ratio between the mass () and the amount of substance (, measured in moles) of any sample of the substance: . The molar mass is a bulk, not molecular, property of a substance. The molar mass is a ''weighted'' ''average'' of many instances of the element or compound, which often vary in mass due to the presence of isotopes. Most commonly, the molar mass is computed from the standard atomic weights and is thus a terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth. The molecular mass (for molecular compounds) and formula mass (for non-molecular compounds, such as ionic salts) are commonly used as synonyms of molar mass, as the numerical values are identical (for all practical purposes), differing only in units ( dalton vs. g/mol o ...

E Number
E numbers, short for Europe numbers, are codes for substances used as food additives, including those found naturally in many foods, such as vitamin C, for use within the European Union (EU) and European Free Trade Association (EFTA). Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority (EFSA). The fact that an additive has an E number implies that its use was at one time permitted in products for sale in the European Single Market; some of these additives are no longer allowed today. Having a single unified list for food additives was first agreed upon in 1962 with food colouring. In 1964, the directives for preservatives were added, in 1970 antioxidants were added, in 1974 emulsifiers, stabilisers, thickeners and gelling agents were added as well. Numbering schemes The numbering scheme follows that of the International Numbering System for Food Additives, International Numbering System (INS) as deter ...

Acidity Regulator
Acidity regulators, or pH control agents, are food additives used to change or maintain pH ( acidity or basicity). They can be organic or mineral acids, bases, neutralizing agents, or buffering agents. Typical agents include the following acids and their sodium salts: sorbic acid, acetic acid, benzoic acid, and propionic acid.Erich Lück and Gert-Wolfhard von Rymon Lipinski "Foods, 3. Food Additives" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2002, Wiley-VCH, Weinheim. Acidity regulators are indicated by their E number, such as E260 (acetic acid), or simply listed as "food acid". Acidity regulators differ from acidulants, which are often acidic but are added to confer sour flavors. They are not intended to stabilize the food, although that can be a collateral benefit. Acidity regulators are also important for food safety, as incorrect pH can result in bacteria growth. See also * Adipic acid * List of food additives * Sodium bicarbonate Sodium bicarb ...

Lebkuchen
(), or () are honey-sweetened German cuisine, German cakes, moulded cookies or bar cookies that have become part of Germany's Christmas traditions. They are similar to gingerbread. Etymology The etymology of ''Leb-'' in the term is uncertain. Proposed derivations include: from the Latin (flat bread), from the Germanic word ''Laib'' (loaf), and from the Germanic word ''lebbe'' (very sweet). Another likely possibility is that it comes from the old term , the rather solid crystallized honey taken from the Beehive, hive, that cannot be used for much beside baking. Folk etymology often associates the name with (life), (body), or (favorite food). means 'cake'. History Sometime in history bakers noticed that honey-sweetened dough would undergo a natural fermentation process when stored in a cool location for several weeks, creating air bubbles that would improve the quality of the bread. was started in November and baked in December after undergoing this fermentation ...

Tunnbröd
Tunnbröd (; literally 'thinbread') is a Swedish version of flatbread. Tunnbröd can be soft or crisp, and comes in many variants depending on choice of grain, leavening agent (or lack thereof) and rolling pin. The dough is made from any combination of wheat, barley, oat and rye; the leavening agent can be both yeast and ammonium carbonate. Soft tunnbröd is commonly used like a crêpe or tortilla as a wrap for other food. A popular fast food dish is soft tunnbröd rolled around mashed potatoes, a hot dog A hot dog is a grilled, steamed, or boiled sausage served in the slit of a partially sliced bun.

Speculoos
Speculoos (; ; ) is a biscuit, originally manufactured in Belgium, made from wheat flour, candy syrup (from beet sugar), fat, and sometimes cinnamon. Speculoos were developed in the 20th century around the area of Verviers, as an alternative for people who could not afford Dutch speculaas. Belgian Speculoos includes fewer spices than Dutch speculaas, as the spices were much more expensive to import to Belgium than to the Netherlands. The origins of speculaas are much older. In the 2020s the names ''speculaas'' and ''speculoos'' are sometimes used interchangeably in Flanders. Brands In Europe, Lotus Speculoos is the most recognized brand. This manufacturer supplied the biscuits individually packaged to the catering industry. In the United States and the United Kingdom, the same company is branded as Lotus Biscoff, short for ''biscuit with coffee''. Company founder Jan Boone Sr. created the original recipe in 1932. In October 2020, Lotus Bakeries decided to omit the word "sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Amerikaner
Black-and-white cookies, half-and-half cookies, and half-moon cookies are round cookies iced or frosted in two colors, with one half vanilla and the other chocolate. They are found in the Northeastern United States and Florida. Black-and-white cookies are flat, have fondant or sometimes royal icing on a dense cake base, and are common in the New York metropolitan area. Half-moon cookies are slightly dome-shaped (convex), have frosting on a fluffy angel cake base, and are common in Central New York and Boston, Massachusetts. The Amerikaner is a similar cookie in German baking. History Designs with contrasting light and dark parts were popular at the beginning of the 20th century, including on baked goods and desserts. Cookies with cake bases also became popular at the time. Culinary historian Stephen Schmidt sees black-and-whites and half-moons as straightforward convergences of the two trends, and compares them to teacakes served in the Southern United States.
