A, which fruits and vegetables have the most pesticide residues?
Strawberries are very susceptible to pests while growing, and cleaning up is inconvenient, so pesticide residues will be higher.
2. green leafy vegetables
Leafy vegetable diseases are very common inwater testing tds meter comparison to other vegetables, so pesticides must be applied frequently, and the more complex the form of leafy vegetables, the more overlapping leaf capsule structure is easier to residual fertilizer, such as common cabbage.
Nectarines, while delicious, have a higher risk of nectarine disease and higher pesticide residues, so we must be more cautious when eating nectarines.
4Apple Because apples have concave places at the top and bottom, it is also easy to deposit fertilizers in these two places, so it is recommended that we peel when eating apples.
Second, how can pesticide residues be reduced before eating?
1st, clean up
Cleaning is the most direct and effective method; the best is to clean under running water, but hand washing is also effective in removing pesticide residues. Naturally, before cleaning, you can also try the following immersion methods.
(1) soak in salt water
When cleaning vegetables, it is recommended that you soak them in salt water first. For part of the fertilizer that is attached to the leaves, salt water soaking can increase the solubility to a certain extent, but it should be noted that if the soaking time is too long, the dissolved fertilizer will be absorbed by the leaves again.
(2) soak in alkaline water
In the cleaning of vegetables like this, you can also try soaking with alkaline water, but also with baking soda, because some fertilizers decompose more easily in an alkaline environment, so it can help reduce pesticide residues, but the effect is limited. If the concentration of alkaline water is very high, or if the soaking time is too long, the cells may crack, allowing pesticide residues to enter the body.
(3) Soak rice in water or flour in water
In addition to the above two methods for cleaning vegetables, you can try rice wash or flour water soaking, which is conducive to absorbing fine dirt from the vegetable surface and thus, to some extent, removing fertilizer.
Some fruits and vegetables are best eaten before they are peeled, which is a very efficient method. Some people believe that the top layer of the fruit contains some nutrition in addition to the rather unfortunate. In fact, the nutrition of the skin of the fruit is exactly like that, of course, after sufficient cleaning, the pesticide residues on the skin are also very little, feel which is more important in fact can be their own discretion.
three, more water
Heating can promote the degradation of pesticide residues in most fertilizers. Some degradation products may not be harmful, while others may be, so it is best to blanch in boiling water and then remove, which is suitable for most vegetables.
Most seawater has a high salinity (>35,000 mg/l). In a reverse-osmosis system, the higher the water's TDS content, the more pressure the pumps must exert to force water through the membranes, which raises the system's energy expenses.
Myth: Water with a high TDS content is safe to drink!...
Even while a TDS level over 300 ppm is safe, it might not be suitable for consumption due to its high mineral concentration and perhaps salty flavor.The TDS level affects the taste, color, and smell of water.
Pure water has a TDS of 1000 mg/L or less. Water is generally regarded as excellent if its TDS is less than 300 and as unsatisfactory if it is more than 1000. The pH number is used as an indicator of both acidity and alkalinity. When a substance has a pH of 7, it is neutral.
