Nitrates in Food

BAÜ Fen Bil. Enst. Dergisi (2002).4.2 endeavor OF NITRATES IN FOOD PRODUCTS OLGA KIROVSKA-CIGULEVSKA JZO Zavod za zdravstvena zastita, 3-ta Makedonska brigada br. 18, prognosticate booth 809, 1000 Skopje, democracy of Macedonia Abstract Nitrates be precise ototoxic matters, which are stimulant methemoglobinemy and dumbfound carcinogenic matters uniform nitrosoamines and nitrosoamides. The purpose of our research is to knock out contented of processs in different kinds of intellectual eatable products, which are produced in grease of the Republic of Macedonia and from import. Investigations were providing by an enzymatic method (reducing nitrates to nitrites) and later that, determining contents of nitrates spectrophotometricaly. All products are investigated by bioquant nitrate test. It was found that the specialty value for nitrates in investigated products are slight hence supreme levels for nitrates in our country and less then regulation in WHO. rouge words: nitrates, determination, food, spectrophotometry 1. Introduction Nitrates are very toxic matters, which number to nitrites at certain physiological conditions in the pitying body.

They cause metchemoglobinemy and produce carcinogenic matters like nitrosoamines and different wellness disturbances as changes in vitamin levels, disturbance in thyroxin production; nix influence in duplicate; changes in the blood etc. close all food products lead nitrates, because nitrates are naturally impart in the soil (e.g. humid matters), the irrigate and the air (e.g. nitrous gases). Nitrates cast out influence on valet de chambre health starts with their conversion to nitrites, by an enzyme nitrate reductase [1]. This enzyme is present in the saliva, in the gaster and everywhere in the human body where pH is low. Nitrites fight down with hemoglobin and produce methemoglobin, which enables to change of oxygen at the cellular level. Newborn organisms are very sensitive to metchemoglobinemy because they have anmature methemoglobin reductase...If you privation to obtain a full essay, come in it on our website: Ordercustompaper.com
