The purpose of our interrogation is to knock out contented of treats in different kinds of intellectual bread and butter products, which are produced in territory of the Republic of Macedonia and from import. Investigations were providing by an enzymatic method (reducing nitrates to nitrites) and later that, determining circumscribe of nitrates spectrophotometricaly. All products are investigated by bioquant nitrate test. It was found that the specialty determine for nitrates in investigated products are little accordingly supreme levels for nitrates in our country and less then regulation in WHO. blusher words: nitrates, determination, food, spectrophotometry 1. Introduction Nitrates are very(prenominal) toxic matters, which number to nitrites at certain physiological conditions in the benignant body.

They cause metchemoglobinemy and produce carcinogenic matters like nitrosoamines and different wellness disturbances as changes in vitamin levels, disturbance in thyroxin production; ostracize influence in sound reflection; changes in the blood etc. to the highest degree all food products drive away nitrates, because nitrates are naturally subject in the soil (e.g. humid matters), the irrigate and the air (e.g. nitrous gases). Nitrates negative influence on world 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 back with hemoglobin and produce methemoglobin, which enables to dishonor of oxygen at the cellular level. Newborn organisms are very sensitive to metchemoglobinemy because they have anmature methemoglobin reductase...If you privation to go a full essay, cast it on our website: Ordercustompaper.com
