2008 China Milk Scandal
The 2008 Chinese milk scandal was a significant food safety incident in China. The scandal involved Sanlu Group's milk and infant formula along with other food materials and components being adulterated with the chemical melamine, which resulted in kidney stones and other kidney damage in infants. The chemical was used to increase the nitrogen content of diluted milk, giving it the appearance of higher protein content in order to pass quality control testing. 300,000 affected children were identified, among which 54,000 were hospitalized, according to the latest report in January 2009. The deaths of six babies were officially concluded to be related to the contaminated milk. The timeline of the scandal dated back to December 2007, when Sanlu began to receive complaints about kidney stones. One of the more notable early complaints was made on 20 May 2008, when a mother posted online after she learnt that Sanlu donated the milk she had been complaining about to the orphans of th ...

Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code. Amino acids can be classified according to the locations of the core structural functional groups, as Alpha and beta carbon, alpha- , beta- , gamma- or delta- amino acids; other categories relate to Chemical polarity, polarity, ionization, and side chain group type (aliphatic, Open-chain compound, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumas Method
The Dumas method in analytical chemistry is a method for the quantitative determination of nitrogen in chemical substances based on a method first described by Jean-Baptiste Dumas in 1826. The Dumas technique has been automated and instrumentalized, so that it is capable of rapidly measuring the crude protein concentration of food samples. This automatic Dumas technique has replaced the Kjeldahl method as the standard method of analysis for nutritional labelling of protein content of foods (except in high fat content foods where the Kjeldahl method is still preferred due to fire risks). Method The method consists of combusting a sample of known mass to a temperature between 800 and 900 °C in the presence of oxygen. This leads to the release of carbon dioxide, water and nitrogen. The gases are then passed over special columns (such as potassium hydroxide aqueous solution) that absorb the carbon dioxide and water. A column containing a thermal conductivity detector at the end is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kjeldahl Method
The Kjeldahl method or Kjeldahl digestion () in analytical chemistry is a method for the quantitative determination of nitrogen contained in organic substances plus the nitrogen contained in the inorganic compounds ammonia and ammonium (NH3/NH4+). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement. Using an empirical relation between Kjeldahl nitrogen content and protein content it is an important method for analyzing proteins. This method was developed by Johan Kjeldahl in 1883. Method The method consists of heating a sample to 360–410 °C with concentrated sulfuric acid (H2SO4), which decomposes ("digests" or "destructs") the organic sample by oxidation to liberate the reduced nitrogen as ammonium sulfate. Hot concentrated sulfuric acid oxidizes carbon (as bituminous coal) and sulfur (see sulfuric acid's reactions with carbon): :C + 2 H2SO4 → CO2 + 2 SO2 + 2 H2O :S + 2 H2SO4 → 3 SO2 + 2 H2O Catalysts like se ...

Cyanuric Acid
Cyanuric acid or 1,3,5-triazine-2,4,6-triol is a chemical compound with the formula (CNOH)3. Like many industrially useful chemicals, this triazine has many synonyms. This white, odorless solid finds use as a precursor or a component of bleaches, disinfectants, and herbicides. In 1997, worldwide production was 160 000 tonnes.Klaus Huthmacher, Dieter Most "Cyanuric Acid and Cyanuric Chloride" Ullmann's Encyclopedia of Industrial Chemistry" 2005, Wiley-VCH, Weinheim. doi 10.1002/14356007.a08 191 Properties and synthesis Properties Cyanuric acid can be viewed as the cyclic trimer of the elusive species cyanic acid, HOCN. The ring can readily interconvert between several structures via lactam-lactim tautomerism. Although the triol tautomer may have aromatic character, the keto form predominates in solution. The hydroxyl (-OH) groups assume phenolic character. Deprotonation with base affords a series of cyanurate salts: : (O)NHsub>3 ⇌ (O)NHsub>2 (O)Nsup>− + H+ (pKa = 6. ...

Non-protein Nitrogen
Non-protein nitrogen (or NPN) is a term used in animal nutrition to refer collectively to components such as urea, biuret, and ammonia, which are not proteins but can be converted into proteins by microbes in the ruminant stomach. Due to their lower cost compared to plant and animal proteins, their inclusion in a diet can result in economic gain, but at too high levels cause a depression in growth and possible ammonia toxicity, as microbes convert NPN to ammonia first before using that to make protein. NPN can also be used to artificially raise crude protein values, which are measured based on nitrogen content, as protein is about 16% nitrogen and the only major component of most food which contains nitrogen is protein. The source of NPN is typically a chemical feed additive, or sometimes chicken waste and cattle manure.http://jas.fass.org/cgi/reprint/57/Supplement_2/221.pdf See also * Nitrogen cycle * Cyanamide * Cyanuric acid * Melamine * 1,3,5-Triazine * Triazines * Chinese pr ...

Melamine Resin
Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. In its butylated form, it is dissolved in ''n''-butanol and xylene. It is then used to cross-link with alkyd, epoxy, acrylic, and polyester resins, used in surface coatings. There are many types, varying from very slow to very fast curing. Curing Melamine-formaldehyde can be cured by heating, which induces dehydration and crosslinking. The crosslinking can be carried out to a limited degree to give resins. Either the melamine-formaldehyde resins or melamine-formaldehyde "monomer" can be cured by treatment with any of several polyols. Applications Construction material The principal use of melamine resin is as the main constituent of high-pressure laminates, such as Formica and Arborite, and of laminate flooring.

2007 Pet Food Recalls
Beginning in March 2007, there was a widespread recall of many brands of cat and dog foods due to contamination with melamine and cyanuric acid. The recalls in North America, Europe, and South Africa came in response to reports of kidney failure in pets. Initially, the recalls were associated with the consumption of mostly wet pet foods made with wheat gluten from a single Chinese company. After more than three weeks of complaints from consumers, the recall began voluntarily with the Canadian company Menu Foods on 16 March 2007, when a company test showed sickness and death in some of the test animals. In the following weeks, several other companies who received the contaminated wheat gluten also voluntarily recalled dozens of pet food brands. One month after the initial recall, contaminated rice protein from a different source in China was also identified as being associated with kidney failure in pets in the United States, while contaminated corn gluten was associated with kid ...

Administration Of Quality Supervision, Inspection And Quarantine
The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China ( zh, 中华人民共和国国家质量监督检验检疫总局, abbreviated AQSIQ) was a ministerial-level department under the State Council of the People's Republic of China that is in charge of national quality, metrology, entry-exit commodity inspection, entry-exit health quarantine, entry-exit animal and plant quarantine, import-export food safety, certification and accreditation, standardization, as well as administrative law enforcement. AQSIQ directly administers provincial Entry-Exit Inspection and Quarantine Bureaus and Bureaus of Quality and Technical Supervision. For example, the Beijing Entry-Exit Inspection and Quarantine Bureau is responsible for collecting health declaration forms, and used thermal imaging to spot passengers with fever due to the 2009 flu pandemic prior to July 16, 2009. In 2018, the AQSIQ was merged with the newly created State Admini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Imprisonment
Life imprisonment is any sentence of imprisonment for a crime under which convicted people are to remain in prison for the rest of their natural lives or indefinitely until pardoned, paroled, or otherwise commuted to a fixed term. Crimes for which, in some countries, a person could receive this sentence include murder, torture, terrorism, child abuse resulting in death, rape, espionage, treason, drug trafficking, drug possession, human trafficking, severe fraud and financial crimes, aggravated criminal damage, arson, kidnapping, burglary, and robbery, piracy, aircraft hijacking, and genocide, crimes against humanity, war crimes or any three felonies in case of three-strikes law. Life imprisonment (as a maximum term) can also be imposed, in certain countries, for traffic offences causing death. Life imprisonment is not used in all countries; Portugal was the first country to abolish life imprisonment, in 1884. Where life imprisonment is a possible sentence, there may als ...

Dairy
A dairy is a business enterprise established for the harvesting or processing (or both) of animal milk – mostly from cows or buffaloes, but also from goats, sheep, horses, or camels – for human consumption. A dairy is typically located on a dedicated dairy farm and milk or in a section of a multi-purpose farm (mixed farm) that is concerned with the harvesting of milk. As an attributive, the word ''dairy'' refers to milk-based products, derivatives and processes, and the animals and workers involved in their production: for example dairy cattle, dairy goat. A dairy farm produces milk and a dairy factory processes it into a variety of dairy products. These establishments constitute the global dairy industry, part of the food industry. Terminology Terminology differs between countries. In the United States, for example, an entire dairy farm is commonly called a "dairy". The building or farm area where milk is harvested from the cow is often called a "milking parlor" or "parl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
