Food is essential to human survival. Hrana je bistvenega pomena za človekovo preživetje. It provides the proteins, carbohydrates, fat, fiber, vitamins, and minerals needed to stay alive, grow, and stay healthy. Zagotavlja beljakovine, ogljikove hidrate, maščobe, vlakna, vitamine, minerale in ki so potrebni, da ostanem živ, rastejo in ostanejo zdravi. Food also serves other social and religious functions. Hrana služi tudi druge socialne in verske funkcije. Seder meals, birthday dinners, awards banquets, wake buffets, and other food-related functions bring people together for a host of cultural purposes. Seder obroki, rojstnodnevne večerje, bankete nagrade, zbudi bifeji in druge hrane, povezanih funkcij, ki jih združuje ljudi za številne kulturne namene. In some fundamental ways, the role of food in human society... V nekaterih temeljnih načinov, vloga hrane v človeški družbi ... Questions about the value and safety of different categories of food are especially difficult to answer because people have been modifying foods almost since the dawn of civilization. Vprašanja o vrednosti in varnosti različnih vrst hrane, še posebej težko odgovoriti, ker ljudje so bili spreminjanje hrane skoraj od začetka civilizacije. In fact, without certain types of food modification, the human species might never have survived on Earth. Dejstvo je, ne da bi nekatere vrste hrane spremembe, človeške vrste, nikoli ne bi preživela na Zemlji. By far the most common and oldest type of food modification used by humans is food preservation. Daleč najpogostejša in najstarejša vrsta spremembe hrane, ki jo je hrana ljudi, ohranjanje. Imagine, for instance, a community... Predstavljajte si, na primer, skupnost ... Various additives help preserve food, but humans have been adding chemicals to foods for many centuries for reasons other than preservation. Različni dodatki pomaga ohranjati hrano, ampak ljudje so bili dodajanje kemikalij v hrano za več stoletij razlogov, ki niso ohranitev. Spices have long been used as food additives not only because they may retard the rate of decay but also because they improve the flavor of food that is bland or that has, in fact, already begun to spoil. Začimbe so že dolgo uporabljajo kot aditivi za živila, ne samo zato, ker lahko upočasni hitrost upadanja, tudi zato, ker izboljša okus hrane, ki je vljudno, ali da je dejansko že začela pokvari. Additives have also been used to enhance the color of food, reflecting the common... Dodatki so se tudi za izboljšanje barvo hrane, ki odraža skupno ... People expressed concern about the adulteration of foods rather early in American history. Ljudje izrazila zaskrbljenost zaradi ponarejanja živil in ne zgodnjih v ameriški zgodovini. For example, in 1641, the General Court of Massachusetts passed a law specifying the size and cost of a loaf of bread. Na primer, leta 1641, Splošno sodišče Massachusettsa sprejel zakon, ki določa velikost in ceno štruce kruha. Any baker who violated the provisions of the act was required to destroy his or her complete stock of bread. Vsak pek, ki krši določbe zakona, je bilo potrebno uničiti svojo celotno zalogo kruha. Similar provisions were made to ensure that butter was not being adulterated by dairy workers. Podobne določbe so bile narejene za zagotovitev, da maslo ni pa s primesmi, ki jih mlečnih delavcev. As in... Kot je noter .. Convincing legislators to pass the nation's first food and drug laws required extraordinary efforts from many concerned and informed individuals. Prepričljive zakonodajalci, da so sprejeti v narodovo prvo hrano in zdravila zakoni zahtevajo izredne napore mnogih zadevnih seznanitvi posameznikov. Near the top of that list was Dr. Harvey W. Wiley, Chief Chemist of the US Department of Agriculture from 1882 to 1907 and the first Chief Administrator of the Food and Drug Administration from 1907 until 1912. Na vrhu tega seznama je bil Dr Harvey W. Wiley, glavni kemik ameriškega ministrstva za kmetijstvo od leta 1882 do leta 1907 in prvi glavni administrator Uprave za hrano in zdravila od leta 1907 do leta 1912. Wiley was born in a log farmhouse near Kent, Indiana, in 1844. Wiley je rodil v kmečki hiši blizu log Kent, Indiana, v 1844. He... On je ... One of the greatest developments in food modification technology during the 20th century was the synthesis of vitamins, which could then be added to foods. Ena od največjih dogodkov v živilski spremembo tehnologije v 20. stoletju je bil sinteza vitaminov, ki bi se nato dodajajo živilom. A major figure in this work was the Swiss chemist Paul Karrer. Pomemben podatek pri tem delu je bil švicarski kemik Paul Karrer. Karrer was born in Moscow on April 21, 1889, of Swiss parents living in Russia at the time. Karrer se je rodil v Moskvi, 21. aprila 1889, švicarskih staršev, ki živijo v Rusiji, v tistem času. He attended the University of Zurich, from which he obtained a Ph.D. Obiskoval je na Univerzi v Zürichu, od katerega je pridobil doktorat in 1911. leta 1911. After a brief period spent at the... Po kratkem obdobju preživel na ... The problem was that chemists knew almost nothing about the existence or chemical structure of vitamins. Težava je bila, da kemiki vedel skoraj nič o strukturi obstoja ali kemično vitaminov. Then, in a flurry of activity, that problem yielded to the efforts of a handful of researchers, including Karrer, from a variety of countries. Potem, v razburjenje dejavnosti, ki so nastale težave prizadevanja peščice raziskovalcev, vključno z Karrer, iz različnih držav. Once these structures were known, chemists were able to begin the process of finding ways to synthesize them so that they could be mass produced as food additives. Ko so bili znani te strukture, kemiki so se lahko začne proces iskanja načinov, da jih sinteze, da bi se jih množično proizvajajo kot aditivi za živila. In 1931, Karrer... Leta 1931 je Karrer ...
