evaluation of n-nitrosamine formation in routine potato cooking
conclusions nitrosamine was formed with conventional potato baking methods with the most nitrosamine formation found on the surface fried samples. nitrites amount in baked potatoes decreased. generally, the amount of nitrosamine in baked potato samples was lower than acceptable limits. results fried samples that were measured by the gas chromatography method had the highest average levels of ni...
متن کاملNutrition and nitrosamine formation.
Nutrition and the fmmation of N-nitroso compounds N-nitroso compounds are an important group of chemical carcinogens that could be involved in human cancer (Magee, 1982). Only a few examples have been found in food and beverages (Assembly of Life Sciences, 1981) but suitable precursors are common dietary constituents (Assembly of Life Sciences, 1981), and the mildly acidic conditions of the sto...
متن کاملN-Nitrosamine formation by cultures of several microorganisms.
Of 38 pure cultures of microorganisms tested, only one, Pseudomonas stutzeri, was capable of forming dimethylnitrosamine from dimethylamine and nitrite during growth. Resting cells of P. stutzeri, Cryptococcus terreus, Escherichia coli, and Xanthomonas campestris formed dimethylnitrosamine, although no nitrosamine was found in growing cultures of the latter three organisms. No nitrosamine was p...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
