Nitrates in Food

BAÜ Fen Bil. Enst. Dergisi (2002).4.2 DETERMINATION OF NITRATES IN FOOD PRODUCTS OLGA KIROVSKA-CIGULEVSKA JZO Zavod za zdravstvena zastita, 3-ta Makedonska brigada br. 18, band booth 809, 1000 Skopje, Republic of Macedonia Abstract Nitrates be truly toxic matters, which are stimulant methemoglobinemy and convey carcinogenic matters standardized nitrosoamines and nitrosoamides. The purpose of our research is to knock out content of nitrates in variant kinds of intellectual nourishment products, which are produced in dirt of the Republic of Macedonia and from import. Investigations were providing by an enzymatic method (reducing nitrates to nitrites) and later that, find out contents of nitrates spectrophotometricaly. All products are investigated by bioquant nitrate test. It was implant that the specialty values for nitrates in investigated products are less thence supreme levels for nitrates in our country and less then linguistic rule in WHO. Key wo rds: nitrates, determination, food, spectrophotometry 1. Introduction Nitrates are actually toxic matters, which number to nitrites at certain physiological conditions in the human luggage compartment.

They cause metchemoglobinemy and produce carcinogenic matters like nitrosoamines and different health disturbances as changes in vitamin levels, disturbance in thyroxin production; negative influence in reproduction; changes in the blood etc. Almost all food products subscribe nitrates, because nitrates are naturally throw in the soil (e.g. wet matters), the water and the air (e.g. nitrous gases). Nitrates negative influence on human health starts with their conversion to n itrites, 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 react with hemoglobin and produce methemoglobin, which enables to transport of type O at the cellular level. Newborn organisms are very stark naked to metchemoglobinemy because they have anmature methemoglobin reductase...If you privation to get a full essay, holy order it on our website: OrderEssay.net
