Blackwell Publishing. Beginning with the work of John Woodward (1665 – 1728) of the Royal College of Physicians, the speculation on saltpeter and fertilisers of the 17th century ended and made way in England for a much more practical approach to agriculture. 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). The interesting question that now comes up is if bacterial reduction of nitrates to nitrites was something that Dr. Polenske speculated about, or was this process generally known by 1891. Clostridium Botulinum – the priority organism, 04. This sped up curing from 21 days to curing in 24 hours. Chapter 09.03: American Icehouses for England: Year-round Curing, Chapter 09.02 – Sweet Cured Irish and Wiltshire Pork, Chapter 08.09 David Graaff’s Armour – A Tale of Two Legends. Crookes, W. 1868/ 69.The Chemical News and Journal of Physical Science, Volume 3. Ladislav NACHMÜLLNER vs The Griffith Laboratories, 4. (Drs. (Aulie, R. P.; 1970), “By 1772 the English pneumatic chemists had isolated “mephitic air,” but they had not yet established its elemental nature. We developed a bacon grid system with custom designed processing aids which is rated the Best Bacon System in the World. Dunker, CF and Hankins OG. A conclusion of the conference was that boric acid, as a food preservative, was to be “regarded with caution.” (The Wichita Daily Eagle, 1890). Smith, Edward. Saltpeter: A Concise History and the Discovery of Dr. Ed Polenske, Releases of the Chemical Laboratory of the Imperial Health Office. This was probably a progression – a search for the natural salpeter found in Turpan. Where life stands still and flavours abound – observing life at the Mardi Himal Eco Village, Kalamati, in Nepal. Protected: Chapter 11.11: The Quilliam Family and the Early Days of Pig Breeding in South Africa. 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. The discovery followed on the discovery of Jean- Jacques-Theophile Schloesing (1824-1919) and Charles-Achille Müntz (1846-1917), when they correctly identified nitrifying bacteria in 1877 in the soil and the importance of identifying denitrifying bacteria, as in the case of nitrifying bacteria, was firstly in terms of its application in agriculture. 2011. 114, No. This was applied at a ratio of 3.4kg salt per 45kg of meat or 1 kg salt per 13 kg of meat. There they penetrate together as far as then roots of plants, where they enter with some particles of soil…” (Aulie, R. P.; 1970: 440). It is found as a white crystalline on rocks or cave walls where there was an abundance of decaying organic matter. Inside the blog, it is featured here: Origins Smallgoods Co, Cape Town, As an ongoing project, I am building up a collection of old meat processing pictures. Nitrite turns into nitric oxide and it is this molecule that is responsible for curing. But did the nitrogen enter as a nitrate or as ammonia? In his 1717 paper, “On the Origin of Nitre,” he described its slow production in the superficial layers of the soil. It is a salt that is used for explosives, meat curing, to fertilize crops, cool beverages and by the late 1800’s, even as a treatment for blood pressure. 10 pounds (4.54kg) of this mixture per 100 pounds (45.36kg) of meat. Saltpeter is the natural mineral source of the chemical potassium nitrate, KNO 3. In India, a large saltpeter industry developed in the north on the boder with Nepal – in the state of Bihar, in particular, around the capital, Patna; in West Bengal and in Uttar Pradesh (Salkind, N. J. Saltpeter Ore is an ore added by Railcraft.It yields two Saltpeter when mined, which can be used as a component in TNT, Strengthened Glass or Fertilizer if Forestry is enabled. Probably a similar progression to the Indian progression. The Chinese and Italians used it to make gunpowder. Johan Rudolph Glauber (1604-1670) detected it in plants, animals, and soil in 1658 . The most complete record of the history of bacon on record. The curing agent was saltpeter. Source: Proceedings of the American Philosophical Society, Vol. “Saltpeter encompassed the “miraculum mundi”, the “material universalis” through which ‘our very lives and spirits were preserved. He asked the question “if nitrates and ammonium salts are interchangeable in the soil, and which is the more efficacious; is one or the other actually the form in which nitrogen is absorbed by plants? He wished first to test whether putrescible organic material in the soil was absolutely indispensable for the absorption of the nitrogen of nitrates, and second, to determine whether there was a prior transformation into ammonium compounds.” (Aulie, R. P.; 1970), “The first part of this hypothesis was easy to test, which he did, by using an artificial soil free of all organic materials. (Shenango Valley News (Greenville, Pensylvania), 26 January 1883, page 3). Click on the logo or go to the index page: Nose-to-Tail and Root-to-Tip: Re-Thinking Emulsions. (Polenske, E. 1891) (5) Note the presence of nitrite in nitrous acid (NO2). Kocher, AnnMarie and Loscalzo, Joseph. (Reasbeck, M: 4) The first reported references to the characteristic flavor of cured meat produced by the addition of saltpeter during meat preservation and curing were made as early as 1835. Schaus and others put the year of the discovery by Griess as 1879. Kaiserliches Gesundheitsamt), Dr. Polenske was a prolific food scientist who made valuable contributions to the examination of food preservatives in the 1880 and 1890’s.
