Mauskopf, MSH. It can be found in any hot and dry biomes under Sand blocks. It was this study of Magendie that gave Boussingault the “clue on which he promptly acted in his first research work. His work laid the foundation for the discovery of the role of microorganisms in fixation of nitrogen as well as the reduction of nitrates to nitrite and ammonia.

Denitrifying bacteria remove one oxygen atom from the nitrogen compound, nitrate, and nitrite is created. It was used since ancient times as medicine and as fertilizer. It is found as a white crystalline on rocks or cave walls where there was an abundance of decaying organic matter. Restructuring of whole muscle meat with Microbial Transglutaminase – a holistic and collaborative approach. This simple discovery later precipitated an avalanche of academic discoveries about nitrate, nitrite, nitric oxide and the mechanisms behind curing. While the other two ingredients to prepare gun powder can be found in the arsenal itself, the third particularly Saltpeter will … Saltpeter, nitrogen and its role in plant and animal, including human nutrition, the nitrogen cycle, nitrifying and denitrifying bacteria are all integrally connected fields of study. (The entire article is accessed by the link and readers are encouraged to take the time to study this article thoroughly). Releases of the Chemical Laboratory of the Imperial Health Office. The history is revealed for the first time ever and I give a comprehensive review of all technical matters related to the production of bacon. Saltpeter is the common name for potassium nitrate (KNO3). There is a record of gunpowder being used in India as early as 1300 BCE, probably introduced by the Monguls. Chemically it is the K-analogue of nitratine. The total weight of dry spices is therefore 6.07kg of which salt is 74% or  3.4kg. In German:  “Arbeiten aus dem Kaiserlichen Gesundheitsamte , 7. He observes that “the way the experiment was set up meant it was not possible for Dr. Polenske to determine if the nitrites were released from the proteins. A National Survey of Nitrite/ Nitrate concentration in cured meat products and non-meat foods available in retail.

Deacon, M;  Rice, T;  Summerhayes, C.  2001. Established in 1900, the Reichsgesundheitsrat supported the Imperial Health Office in its tasks. The Life and Times of Ladislav NACHMÜLLNER – The Codex Alimentarius Austriacus. Here, a network of caves was discovered in 2003 in the Laojun Mountains in Sichuan Province. Saltpeter is the natural mineral source of the chemical potassium nitrate, KNO 3. The chief applications of Chile saltpetre are in the nitric acid industry and particularly as a fertilizer. While it is difficult to find saltpeter, you can still purchase potassium nitrate, which is used to make smoke bombs and certain other fireworks. When testing the brine, he found that nitric acid (Salpetersaeure; HNO3) was reduced through “the microorganisms induced reduction” to nitrous acid (Salpetriger Saeure; HNO2) and ammonial (ammonia). It has oxidizing properties that make it useful as a rust inhibitor for metals. Occurrences of “mild cure” in English Newspapers, The Master Butcher from Prague, Ladislav NACHMÜLLNER, 2. (1, 2). He speculated on the chemical relationships that bind them together. . He wrote that “It would be of fundamental importance in the history of nutrition, if the source could be determined of the nitrogen which is found in such great abundance in the animal body”. Today, it has many uses in both the laboratory and the larger world. The value of nitrogen in plant and animal nutrition was elucidated by scientists, particularly by Boussingault. Kuhlmann thought that nitrates were formed by the oxidation of ammonia in the soil. Later, massive deposits of sodium nitrite were discovered in the Atacama Desert of Chile and Peru and became known as Chilean Saltpeter. (Polenske, E.  1891). This is the story. A typical curing mix used during the late 1800’s to the middle of the 1900’s for dry cured bacon was a mix of 10 pounds salt, 3 pounds of brown sugar, 6 ounces of black pepper and 3 ounces of saltpeter. My son, Triatan sells the system through his company GMT. The most complete record of the history of bacon on record. Dr. Polenske undoubtedly drew on this knowledge when he wrote that the formation of nitrites and ammonia from saltpeter is achieved through  a “microorganisms induced reduction.”, He recognised the controversial nature of his discovery and wrote that “since the same decomposition products (in particular nitrous acid; HNO2) are also found in the cured meat it is likely that this subject matter will receive sharp comment.”  He referred to the fact that the presence of nitrite in drinking water was a matter of great concern in the 1890’s and was even reported on in weekly newspapers. Protected: Chapter 11.11: The Quilliam Family and the Early Days of Pig Breeding in South Africa. Sci. Not all salt was absorbed into the meat, but the meat was regularly re-salted during then curing time which means that this ratio would be applied many times over before curing was complete. But did the nitrogen enter as a nitrate or as ammonia? (Cressy, David, 2013:  12), Peter Whitehorney, the Elizabethan theorist who wrote in 1500’s, said about saltpeter, “I cannot tell how to be resolved, to say what thing properly it is except it seemeth it hath the sovereignty and quality of every element”. "Gunpowder, Explosives and the State: A Technological History"; Brenda J. Buchanan; 2006, "Jpn J Conservative Dentistry"; The Effects of Potassium Nitrate...; Keiko Enomoto, et al. The subject of preservatives in meat and whether they are safe to use has been one of the subjects he studied. The curing agent was saltpeter. Caves and sheltered areas were ideal locations for saltpeter to form, because they offered protection from the elements and they provided the … For organic matter you can use straw with straw being nothing more than cut grass. The obvious loss of nitrogen in the curing process caused him to view cured meat as inferior to fresh meat. . He married Möller and passed away in 1911 in Berlin, Germany. (Qin, Y., et al; 2012)  (THE TARIM MUMMIES OF CHINA)  Its strategic location on the silk road, the evidence of advanced medical uses of nitrates from very early on and the ethnic link with Europe of people who lived here, all support this hypothesis. Bacon curing was described in 1876 by Edward Smith as the process whereby pork is “preserved by salt and saltpeter.”  (Smith, 1876: 64). A cargo ship at the Cape: (Wikipedia. She has written for the "Financial Times," "Barron's," "Christian Science Monitor," and "Rheinischer Merkur" as well as specialist publications on the energy and financial industries and the European, Middle Eastern, African, Asian and Latin American regions. Nitrite Free Bacon: Barriers against clostridium botulinum, Removal of Nitrite from Meat Curing Systems, Weight Loss During Chilling and Freezing of Meat, 02. Boussingault and the Nitrogen Cycle. Salt peter typically refers to the chemical compound potassium nitrate, though it may also refer to sodium nitrate. On farms, long curing is less of a problem, but for a commercial curing operation, it means that you keep large stocks of bacon that are in the process of curing. C & T Harris and their Wiltshire bacon cure – the blending of a legend, A Most Remarkable Tale: The Story of Eskort, Eskort and Enterprise: Echoes in the first Union of South Africa cabinet, Seekombuis – visiting with Neels and Attie, The Anglo-Boer War and Bacon: Old Enemies Become Friends.
