Boiling, steaming and frying also reduce nitrate contents. It was observed that, as other studies, frying has the highest impact on nitrate reduction in potatoes compared to other two methods. The maximum nitrite reduction was obtained in the boiling method.tds meter

Vegetables particularly rich in nitrates include green leafy vegetables such as spinach and lettuce as well as fennel, rocket, radishes, Chinese cabbage, and parsley [3, 5, 6].
The Nitrate content of foods may be determined by means of azo-dye coupling after reduction of the nitrate with the aid of active cadmium produced in the sample solution.
Harmful germs sometimes found on leafy greens include E. coli, norovirus, Salmonella, Listeria, and Cyclospora.
-A scientific approach to food safety
greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested. The presence of nitrate ions in organic matter measurably increases conductivity.
Nitrate test strips are often used to test fertilizer run-off in agricultural areas. This strip is very sensitive to light and moisture, so be sure to keep the vial tightly sealed. Make sure to reseal the bottle immediately after opening to prevent the moisture from ruining them.
Many traditional meat products are required to contain curing ingredients (nitrate and/or nitrite) with strict usage requirements (eg. bacon) or to meet consumer expectations (eg. hams, hot dogs, etc.).
