Nitrates are salts of nitric acid that some gardeners use to grow vegetables and fruits. People buy fresh cucumbers and tomatoes without thinking that they can be hazardous to their health. Unfortunately, it is impossible to completely get rid of nitrates, but it is possible to reduce their content.
Most of the nitrates are found in greens and vegetables grown in greenhouses and greenhouses. Early root and leafy vegetables are considered champions in nitrate content: dill, radishes, salads, tomatoes, parsley, cucumbers, green onions, cabbage. They also have the ability to accumulate nitrates: carrots, pumpkin, beets, watermelon, eggplant and zucchini. Most of the salts of nitric acid accumulate in the cuttings of plant leaves and at the bases of fruits. You can identify nitrates in carrots and beets by the white heart. In watermelons, excess nitrates can be seen by the yellow veins.
You can accurately determine the amount of nitrates in fruits, herbs and vegetables using a special device - a nitrate meter, which works with a metal probe or electrodes. But since not everyone has such an opportunity, one should try to reduce the intake of nitrates into the human body.
Nitrates and various harmful compounds leave vegetables during heat treatment - during cooking. For example, boiled potatoes contain 20% less nitrates, while carrots cut the nitrate content by half. Some housewives, while cooking borscht or soup, first boil vegetables, then drain the water, pour in a new one. This has a significant disadvantage - vitamins and minerals also merge.
It is possible to reduce the amount of nitrates if greens, fruits and vegetables are thoroughly washed and cleaned. For washing, use a baking soda solution, dilute a tablespoon of baking soda in one liter of water. Wash vegetables in it, and then rinse with clean water. Cut cucumbers and carrots on both sides by one centimeter, cut off the tops of tomatoes and radishes. Do not use cabbage stumps and thick veins of cabbage.
Soak parsley, lettuce, dill and green onions in cold water for half an hour before eating. But at the same time, some of the vitamins will also go away. Start growing greens at home on the windowsill, then you will be sure that there is a minimum amount of nitrates in it.
