\"Spinach<\/a>
L\u00c9pinard is the food with the most important source of nitrate<\/figcaption><\/figure>\n

British authors [Kingston University; Kingston upon Thames, Surrrey, United Kingdom] introduce 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 are as follows:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

The authors draw attention to spinach powder<\/strong>. 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.<\/p>\n
