Nitrates are the salts of nitric acid,extracted by plants from the ground in the process of growth. These salts are absolutely harmless, but only until they reach our body. Getting inside, harmless nitrates in vegetables turn into extremely unsafe nitrites, capable of blocking cellular respiration. Most nitrates are found in early vegetables and early greens, since an increased rate of nitrogen-based fertilizers is applied to accelerate maturation. It should be taken into account that the content of nitrates in vegetables grown in greenhouses is usually higher than in those grown in open ground.

content of nitrates in vegetablesSize is important! Most nitrates can be found in beetroot, radish and cabbage. The least quantity of nitrogen is found in eggplants, Bulgarian pepper, tomatoes, green peas and garlic. The size of the fruit is directly proportional to the content of nitrates. Nitrates in vegetables of ripe are kept in smaller quantity, than in unripe. Heat treatment can significantly reduce their number. Thorough washing of fruits reduces nitrates in vegetables by 10 - 15%. When cooking potatoes, up to 50 percent of nitrates are in the broth, the same happens with beetroot, carrots, and cabbage. Fry reduces nitrates in vegetables by 15 percent, and frying in deep fat - by 60. But the champion for the destruction of nitrates is steaming!

Canned and salted vegetables have morelow level of nitrates in comparison with fresh fruits. The process of souring can reduce their content by 2-3 times. But fresh vegetable juices differ even with a higher level of nitrogen salts than the original roots.

Forewarned is forearmed!

- Skin peeling in any root crops reduces the content of nitrogen salts by half.
- Cabbage stump, covering sheets and thickened veins of leaves are to be removed.
- The core of the carrot contains the largest amount of nitrates, and also cut the carrots from the ends.
- Boiled beets must be pre-cleaned of peel, tip and tip.
- In the tops of courgettes and cucumbers contains the least amount of nitrates, and in the pedicels - the largest.
- Leeks accumulate nitrates below, in the white part of the vegetable.
- Soaked, pre-washed greens, cleared of stems, also has a low level of nitrates.
- The radish of the elongated form contains a greater quantity of nitrogen salts than the round radish.
- Early watermelons ripen ahead of time due to a large number of fertilizers introduced into the soil. When eating these berries, it is better to refrain from careful eating of slices.
- Storage of fruits and vegetables with propertemperature (for example, in a refrigerator) also helps to prevent the transition of nitrates to dangerous nitrites. Spoiled, rotten fruits should not be eaten in any way!

nitrate meter in vegetablesBest of all solves the above problemnitrate tester! This small nitrate meter in vegetables allows measuring their level in fresh fruits. All you need to do is pierce the skin of the fetus with the tester. The numbers of nitrates in the vegetable under test will be displayed on the color display. In addition, the device contains nitrate content for 30 kinds of fruits.
