Hippolyte Mège-Mouriès
Hippolyte Mège-Mouriès (; 24 October 1817 – 31 May 1880) was a French chemist and inventor who is famous for his invention of margarine. Early life Hippolyte Mège was born on 24 October 1817 in Draguignan to Jean Joseph-Emmanuel Mège and his wife, Marie Marguerite Mouriès. The son of a primary school teacher, he added his mother's surname to his own around 1850 to distinguish himself from others of the same last name. Legal documents, however, often used "Mège". In 1838, Mège obtained a job as a pharmacist in the central pharmacy of the Hôtel-Dieu hospital in Paris. Early work Mège started to publish original contributions in applied chemistry, such as a form of the syphilis medicine Copahin refined with nitric acid that eliminated side-effects. He also obtained patents for effervescent tablets, for techniques in paper making and sugar refining, and for the tanning of leather using egg yolks. By 1852, Mège-Mouriès was studying the chemistry of foods. He adde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draguignan
Draguignan (; oc, Draguinhan) is a commune in the Var department in the administrative region of Provence-Alpes-Côte d'Azur (formerly Provence), southeastern France. It is a sub-prefecture of the department and self-proclaimed "capital of Artillery" and "''Porte du Verdon''". The city is from Saint-Tropez, and from Nice. Name and motto According to legend, the name of the city is derived from the Latin name "Draco/Draconem" (''dragon''): a bishop, called Saint Hermentaire, killed a dragon and saved people. The Latin motto of Draguignan is ''Alios nutrio, meos devoro'' (I nourish others, I devour my own). Geography The elevation is 200 m. The highest hill near Draguignan is Malmont (551 m). The main river near Draguignan is the Nartuby. The city is set in a valley NW-SE, about wide. Climate Draguignan's climate is the same as the normal conditions of the Mediterranean climate. The nights of frost are rare and the negative temperatures occur o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society Of Arts
The Royal Society for the Encouragement of Arts, Manufactures and Commerce (RSA), also known as the Royal Society of Arts, is a London-based organisation committed to finding practical solutions to social challenges. The RSA acronym is used more frequently than the full legal name (The Royal Society for the Encouragement of Arts, Manufactures and Commerce). The RSA's mission expressed in the founding charter was to "embolden enterprise, enlarge science, refine art, improve our manufacturers and extend our commerce", but also of the need to alleviate poverty and secure full employment. On its website, the RSA characterises itself as "an enlightenment organisation committed to finding innovative practical solutions to today's social challenges". Notable past fellows (before 1914, members) include Charles Dickens, Benjamin Franklin, Stephen Hawking, Karl Marx, Adam Smith, Marie Curie, Nelson Mandela, David Attenborough, Judi Dench, William Hogarth, John Diefenbaker, and T ...

Working Class
The working class (or labouring class) comprises those engaged in manual-labour occupations or industrial work, who are remunerated via waged or salaried contracts. Working-class occupations (see also " Designation of workers by collar colour") include blue-collar jobs, and most pink-collar jobs. Members of the working class rely exclusively upon earnings from wage labour; thus, according to more inclusive definitions, the category can include almost all of the working population of industrialized economies, as well as those employed in the urban areas (cities, towns, villages) of non-industrialized economies or in the rural workforce. Definitions As with many terms describing social class, ''working class'' is defined and used in many different ways. The most general definition, used by many socialists, is that the working class includes all those who have nothing to sell but their labour. These people used to be referred to as the proletariat, but that term has gone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butter
Butter is a dairy product made from the fat and protein components of churned cream. It is a semi-solid emulsion at room temperature, consisting of approximately 80% butterfat. It is used at room temperature as a spread, melted as a condiment, and used as a fat in baking, sauce-making, pan frying, and other cooking procedures. Most frequently made from cow's milk, butter can also be manufactured from the milk of other mammals, including sheep, goats, buffalo, and yaks. It is made by churning milk or cream to separate the fat globules from the buttermilk. Salt has been added to butter since antiquity to help to preserve it, particularly when being transported; salt may still play a preservation role but is less important today as the entire supply chain is usually refrigerated. In modern times salt may be added for its taste. Food colorings are sometimes added to butter. Rendering butter, removing the water and milk solids, produces clarified butter or '' ghee'', whi ...

Skimmed Milk
Skimmed milk (British English), or skim milk (American English), is made when all the milkfat is removed from whole milk. It tends to contain around 0.1% fat. Background Historically, skimmed milk was used for fattening pigs, and was recommended as "not only the very best supplement for growing pigs, but is of almost equal value for fattening purposes" as it "furnishes a complete protein" and makes the feed "more palatable". Terminology In the United Kingdom, milk is traditionally marketed and labelled as follows: * Whole milk (around 3.0–4% fat) – Plastic bottles marketed in blue packaging. * Semi-skimmed milk (around 1.8% fat) – Plastic bottles are marketed in green packaging. * Skimmed milk (around 0.1% fat) – Plastic bottles are marketed in red packaging. * Channel Island milk (around 5–5.5% fat) Often referred to as gold top, although this varies. Additionally, some supermarkets in the UK now market milk as: * 1% fat milk – Normally sold in purple or or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tallow
Tallow is a rendered form of beef or mutton fat, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton fat. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. The adjacent diagram shows the chemical structure of a typical triglyceride molecule. The solid material remaining after rendering is called cracklings, greaves, or graves. It has been used mostly for animal food, such as dog food. In the soap industry and among soap-making hobbyists, the name tallowate is used informally to refer to soaps made from tallow. Sodium tallowate, for example, is obtained by reacting tallow with sodium hydroxide (lye, caustic soda) or sodium carbonate (washing soda). It consists chiefly of a variable mixture of sodium salts of fatty acids, such as oleic and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beef
Beef is the culinary name for meat from cattle (''Bos taurus''). In prehistoric times, humankind hunted aurochs and later domesticated them. Since that time, numerous breeds of cattle have been bred specifically for the quality or quantity of their meat. Today, beef is the third most widely consumed meat in the world, after pork and poultry. As of 2018, the United States, Brazil, and China were the largest producers of beef. Beef can be prepared in various ways; cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often ground or minced, as found in most hamburgers. Beef contains protein, iron, and vitamin B12. Along with other kinds of red meat, high consumption is associated with an increased risk of colorectal cancer and coronary heart disease, especially when processed. Beef has a high environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultura ...

Margaric Acid
Margaric acid, or heptadecanoic acid, is a saturated fatty acid. Its molecular formula is CH3(CH2)15CO2H. Classified as an odd-chain fatty acid, it occurs as a trace component of the fat and milkfat of ruminants. Salts and esters of margaric acid are called heptadecanoates. Its name is derived from the Ancient Greek μάργαρος (''márgar(on)''), meaning "pearl(y)", due to its appearance. Semiochemistry For many species, margaric acid plays a role as a semiochemical - specifically it possesses pheromonic and allomonic properties. Margaric acid has been identified in the subcaudal gland secretions of the European badger (''Meles meles'') and in the occipital gland secretions of male Bactrian camels (''Camelus bactrianus'') where it is one of the many pheromonic chemicals responsible for aiding in the finding and selection of mates. Margaric acid is an attractant of the khapra beetle (''Trogoderma granarium'') and the yellow fever mosquito (''Aedes aegypti'') but is a r ...

Fatty Acid
In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsatur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napoleon III
Napoleon III (Charles Louis Napoléon Bonaparte; 20 April 18089 January 1873) was the first President of France (as Louis-Napoléon Bonaparte) from 1848 to 1852 and the last monarch of France as Emperor of the French from 1852 to 1870. A nephew of Napoleon I, he was the last monarch to rule over France. Elected to the presidency of the Second Republic in 1848, he seized power by force in 1851, when he could not constitutionally be reelected; he later proclaimed himself Emperor of the French. He founded the Second Empire, reigning until the defeat of the French Army and his capture by Prussia and its allies at the Battle of Sedan in 1870. Napoleon III was a popular monarch who oversaw the modernization of the French economy and filled Paris with new boulevards and parks. He expanded the French overseas empire, made the French merchant navy the second largest in the world, and engaged in the Second Italian War of Independence as well as the disastrous Franco-Prussian W ...

Food Processing
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods. Some food processing methods play important roles in reducing food waste and improving food preservation, thus reducing the total environmental impact of agriculture and improving food security. Primary food processing is necessary to make most foods edible, and secondary food processing turns the ingredients into familiar foods, such as bread. Tertiary food processing has been criticized for promoting overnutrition and obesity, containing too much sugar and salt, too little fiber, and otherwise being unhealthful in respect to dietary needs of humans and farm animals.
