The Influence of Pork Fat on Kno3

Nitrates and nitrites are commonly used preservatives and additives in conjunction with sorbates and ascorbates. in the curing of meat. Studies have shown however, that nitrosoamines, well-known carcinogens, are produced from the reaction of nitrate or nitrite, and secondary or tertiary amines. Certain naturally occurring quaternary ammonium compounds react with the nitrate/nitrite ensuing the production of N-nitrosatable compounds under certain conditions. Consequently, the safety assessment of potassium nitrate as a chemical addition to food, ought to encompass the toxicity of potential endogenously formed nitrite and N-nitroso compounds as well. Given that food further undergo processing before it is finally eaten, the broiling, frying, cooking, or addition of other food ingredients may either enhance or diminish the assumed mutagenic properties of additives. like potassium nitrate in food. In the current study, the mutagenicity of potassium nitrate was assayed in the presence and absence of lard (expressed from pork fat), using the micronucleus test in the bone marrow of mice. Read

Low Cost Sensor for E. Coli/ Colliform Detection in Water

This paper reports the fabrication of a handheld, simple to use sensor which detects contamination by deadly strains of E coli in drinking water. E. coli 0157, predominately 0157:H7, has been implicated as the causative organism of hemolytic uremic syndrome and hemorrhagic colitis. The sensor works based on irreversible color changes that occur subsequent to hydrolysis of a chromogenic substrate by a ß-galactosidase enzyme of E.coli. Read
