Trisodium Citrate
Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor, and is a mild alkali. Applications Foods Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix, ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine, amongst others. Sodium citrate can be used as an emulsifying stabilizer when making cheese. It allows the cheese to melt without becoming greasy by stopping the fats from separating. Buffering As a conjugate base of a weak acid, citrate can pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monosodium Citrate
Monosodium citrate, more correctly, sodium dihydrogen citrate (Latin: ''natrium citricum acidulatum''), is an acid salt of citric acid. Disodium citrate and trisodium citrate are also known. It can be prepared by partial neutralisation of citric acid with an aqueous solution of sodium bicarbonate or carbonate. It has a slightly acidic taste. :NaHCO3 + C6H8O7 → NaC6H7O7 + CO2 + H2O :Na2CO3 + 2C6H8O7 → 2NaC6H7O7 + CO2 + H2O It is highly soluble in water and practically insoluble in ethanol. Monosodium citrate is used as an anticoagulant in donated blood. It is used as an alkalinizing agent Alkalinizing agents are drugs used to manage disorders associated with low pH. For example, they may be used to treat acidosis due to kidney failure. Used for oral or parenteral therapy, sodium bicarbonate is the commonly preferred alkalinizin ... to prevent kidney stone disease. The crystals form as nearly perfect cubes.

Gelatin Dessert
Gelatin desserts (also Jelly or Jello) are desserts made with a sweetened and flavoured processed collagen product (gelatin). This kind of dessert was first recorded as jelly by Hannah Glasse in her 18th-century book ''The Art of Cookery'', appearing in a layer of trifle. Jelly is also featured in the best selling cookbooks of English food writers Eliza Acton and Isabella Beeton in the 19th century. They can be made by combining plain gelatin with other ingredients or by using a premixed blend of gelatin with additives. Fully prepared gelatin desserts are sold in a variety of forms, ranging from large decorative shapes to individual serving cups. Popular brands of premixed gelatin include: Aeroplane Jelly in Australia, Hartley's (formerly Rowntree's) in the United Kingdom, and Jell-O from Kraft Foods and Royal from Jel Sert in North America. In the US and Canada this dessert is known by the genericized trademark "jello". History Before gelatin became widely available ...

Luis Agote
Luis Agote (September 22, 1868 – November 12, 1954) was an Argentine physician and researcher. He was the first to perform a non-direct blood transfusion using sodium citrate as an anticoagulant. The procedure took place in Rawson hospital in the city of Buenos Aires on November 9, 1914. Agote was the first to perform this procedure in the Americas. Agote worked independently and separately from the Belgian surgeon Albert Hustin, who discovered that sodium citrate in tolerable quantities could anticoagulate blood for transfusion on March 27, 1914. Biography Agote was the son of a politician. He studied first in the Colegio Nacional de Buenos Aires, and then at the University of Buenos Aires Faculty of Medicine, where he was also a teacher. He graduated as a doctor in 1893 with a thesis about suppurative hepatitis. He became Secretary of the National Department of Hygiene in 1894 and became head of the leper hospital in 1895 on the island of Martin Garcia. He was elected Congre ...

Glucose
Glucose is a simple sugar with the molecular formula . Glucose is overall the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, the most abundant carbohydrate in the world. In energy metabolism, glucose is the most important source of energy in all organisms. Glucose for metabolism is stored as a polymer, in plants mainly as starch and amylopectin, and in animals as glycogen. Glucose circulates in the blood of animals as blood sugar. The naturally occurring form of glucose is -glucose, while -glucose is produced synthetically in comparatively small amounts and is less biologically active. Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benedict's Reagent
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. It is often used in place of Fehling's solution to detect the presence of reducing sugars. The presence of other reducing substances also gives a positive result.Collins Edexcel International GCSEBiology, Student Book () p.42-43 Such tests that use this reagent are called the Benedict's tests. A positive test with Benedict's reagent is shown by a color change from clear blue to brick-red with a precipitate. Generally, Benedict's test detects the presence of aldehydes, alpha-hydroxy-ketones, and hemiacetals, including those that occur in certain ketoses. Thus, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone and gives a positive test because the base in the reagent converts it into the aldoses glucose and mannose.

Alka-Seltzer
Alka-Seltzer is an effervescent antacid and pain reliever first marketed by the Dr. Miles Medicine Company of Elkhart, Indiana, United States. Alka-Seltzer contains three active ingredients: aspirin (acetylsalicylic acid) (ASA), sodium bicarbonate, and anhydrous citric acid. The aspirin is a pain reliever and anti-inflammatory, the sodium bicarbonate is an antacid, and the citric acid reacts with the sodium bicarbonate and water to form effervescence. It was developed by head chemist Maurice Treneer. Alka-Seltzer is marketed for relief of minor aches, pains, inflammation, fever, headache, heartburn, stomachache, indigestion, acid reflux and hangovers, while neutralizing excess stomach acid. It was launched in 1931. Its sister product, Alka-Seltzer Plus, treats cold and flu symptoms. A wide variety of formulae, many using acetaminophen (paracetamol) instead of aspirin, are available under the sister brand. Product information Alka-Seltzer is a combination of sodium bicar ...

Antacid
An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach. Some antacids have been used in the treatment of constipation and diarrhea. Marketed antacids contain salts of aluminum, calcium, magnesium, or sodium. Some preparations contain a combination of two salts, such as magnesium carbonate and aluminium hydroxide (e.g. hydrotalcite). Medical uses Antacids are available over the counter and are taken by mouth to quickly relieve occasional heartburn, the major symptom of gastroesophageal reflux disease and indigestion. Treatment with antacids alone is symptomatic and only justified for minor symptoms.U.S. Department of Health & Human Services. Agency for Healthcare Research and Quality 23 September 201Consumer Summary – Treatment Options for GERD or Acid Reflux Disease: A Review of the Research for Adults Alternative uses for antacids include constipation, diarrhea, hyperphosphatemia, and urinary alkali ...

Acid
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Inf ...

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 * Adipate * List of food additives * Sodium bicarbonate Sodium bicarbonate ( IUP ...
