“…Sodium nitrite also acts as a preservative [2], and suppresses propagation of pathogenic Escherichia coli O157 and Clostridium botulinum [9,10]. However, nitrite can combine with amines in food and form carcinogenic nitrosamines and cause methemoglobinemia [11][12][13]. Whereas humans may select food based on its color, this is likely not important for dogs because they have limited color perception [14].…”

The nitrite concentrations in different commercial dog foods were measured. Differences in the nitrite concentrations were observed, and were mainly attributed by the type of meat used as the main ingredient and its proportion in the final product. Standard doses for nitrite of 2.5 and 4.6 mg/kg were calculated using different methods, and these values are both much lower than the standard dose for human food. The nitrite concentrations in some of the samples in this study exceeded the 2.5 mg/kg value.

A quantitative analysis was developed for eight acidic and neutral preservatives in foods and daily necessities using the inline dialysis-IC combined with hydrophobic anion-exchange separation. The eight preservatives were dialyzed by inline dialysis and separated on a hydrophobic anion exchange column. Under the optimized separation conditions, the detection limits (S/N = 3) for the eight preservatives were from 0.08 to 0.66 mg L(-1), moreover, a good linearity (R(2) > 0.998) for each preservative was obtained in the range to 100 mg L(-1). Although the dialysis rate of the neutral preservatives was not so high, a good repeatability (RSD, n = 8) of less than 1.5% for the eight preservatives was obtained. The inline dialysis-IC method was applied to the determination of the preservatives in foods and daily necessities. The preservatives were quantified without any interference. The proposed method will be useful for the determination of the preservatives in foods and daily necessities containing high concentration matrices.

“…Then, a quantitative analysis for NO 2 ¹ has been become very important in these days. So far, nitrite-ions are usually analyzed by instrumental methods such as UV vis spectrophotometry 8), 9) or ion chromatography, 10) however these techniques require complicated handling process for the measurements and are not suitable for the use at on-site monitoring. Therefore, a compact and simple sensor device has been become very important in these fields.…”

Detection of nitrite-ion has become very important for various industrial fields due to its wide application range such as food additives and a rust preventive agent for steels. In this study, we attempted at developing an advanced method to produce layered perovskite-type cuprates based thick-film device for highly sensitive electrochemical sensor for nitrite-ion with a capacity of wide concentration range. Here, layered perovskite-type oxide powders could be synthesized by a polymer precursor method which was deposited on alumina supports with gold electrode by an electrophoretic deposition method. The sensor performance was measured by an amperometric method for nitrite-ion detection. It was found that the Gd 2 CuO 4-based electrode showed fast and good linear responses to nitrite-ion for a wide range of concentration.
