Researchers from Kingston University; Surrrey, United Kingdom, presented a new, accurate, reliable ion chromatography method for measuring nitrate NO3<\/sub>–<\/sup> <\/span>and nitrite NO2<\/sub>–<\/sup> <\/span>in food products [The primary aim of this study was to develop a new accurate, reliable and robust ion chromatography<\/em>].<\/p>\n

Their method of measuring nitrate and nitrite contents is applied to three vegetable juices: beet, black radish and celery juices, and to five vegetable powders: beet, spinach, celery, carrot and tomato powders.<\/p>\n

On average, the results were as follows:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Samples<\/strong><\/td>\nNitrate NO3<\/sub>concentration –<\/sup><\/strong><\/p>\n

Tomato powder<\/strong><\/td>\n113<\/strong><\/td>\n27<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The authors drew attention to spinach powder. While the results of measurements of nitrate NO concentrations3<\/sub>–<\/sup> and nitrite NO2<\/sub>–<\/sup> in beet juice give rise to significant variations when, on the same batch, the measurements are repeated several times a day or from one day to the next, the results of the measurements of nitrate NO concentrations3<\/sub>–<\/sup> and in nitrite NO2<\/sub>–<\/sup> spinach powder are, on the contrary, remarkably stable from one control to another.
