CONTENTS OF NITRATE AND NITRITE IN SOME NIGERIAN FOOD GRAINS AND THEIR POTENTIAL INGESTION IN THE DIET - A SHORT REPORT

Nitrate and nitrite levels were determined in three varieties of food grains. Nitrate in cereals varied from 120.0 in rice to 1000.0 mg/kg in maize, while nitrite was from 0.026 in rice to 0.106 mg/kg in maize varieties. Their levels in cowpea varied between 710 and 1845 mg/kg for nitrate and 0.033 and 0.062 mg/kg for nitrite. On cooking, nitrate levels decreased in maize and cowpea varieties while an increase occurred in the rice samples. Nitrite levels increased in all the food grains on cooking. Daily intake estimates indicate that the nitrate and nitrite contents of the food grains seem to satisfy the current acceptable daily intake.
