Use rice washing water to clean fruits and vegetables, the more you wash them, the cleaner they get?
Edible rice, grains and cereals are generally sprayed with pesticides, more or less will be residual insect eggs, dust and microbial conditions, so the dirty water used to wash rice and then to clean fruits and vegetables, only to make fruits and vegetables more unclean. The best way to clean fruits and vegetables, or use the flow of tap water, the best effect!
Extending the soaking time of fruits and vegetables can reduce pesticide residues?
Pesticides in water can be dissolved limited, so generally soak about 12 to 15 minutes can be, but it should be noted that there are many water-soluble nutrients in fruits and vegetables, soaking too long will make the nutrient loss. If some thick shell beans, such as soybeans, black beans, can be soaked for a longer time, about 20 minutes or less, and then change the water to clean.
Like the thicker shell of soybeans, it is recommended that you can rinse and soak them to remove the pesticide residue from the skin by constantly changing the water.
Use a veggie cleaner and your fruits and vegetables will be clean, no more washing!
Vegetable and fruit cleaners are usually complex formulas. Even if you use cleaners that emphasize “natural”, you should consider the percentage of naturalness and whether chemical processing procedures are used, and not just believe in advertising messages.
It is difficult for the general public to distinguish the effectiveness of detergents, and even if they are effective in removing pesticide residues, they still have to think about whether the detergent itself has residual problems. Therefore, after soaking or scrubbing with vegetable and fruit cleaners, it is still necessary to wash the fruits and vegetables with water again.
Add salt water to wash fruits and vegetables, can quickly break down pesticides?
Salt will break down into nano ions and chloride ions, both of which will reduce the cleaning ability of the water; He Zhongping pointed out that salt water will dehydrate vegetables if soaked for too long, which will not help remove pesticides at all, but will allow pesticides to continue to remain on fruits and vegetables.
Although salt has a bactericidal effect, but need to have a certain concentration and time to play, the general household brine concentration is not enough to sterilize, and may cause pesticide residues continue.
Buy organic fruits and vegetables will not have to wash?
The general definition of organic should be “no pesticide spraying”, “no chemical fertilizer”, so many people buy organic fruits and vegetables, in the cleaning is relatively lax, and even directly eat raw.
In addition to pesticides and fertilizers, there are also biological contaminants in life, such as bacteria, viruses, as well as insect eggs, parasites and dust in fruits and vegetables, all of which still need to be removed by cleaning.
The appearance of fruits and vegetables with insect bites is a guarantee of safety?
Most people will think that fruits and vegetables have insect bites, representing less pesticides or no pesticides, in fact, this is wrong, you can not just rely on the appearance to determine whether the safety of fruits and vegetables, but to think about whether it is because after the insect bites, the farmer began spraying pesticides?
Insect-bitten kohlrabi is not necessarily a guarantee of safety without pesticides, some pesticides can only target some of the pests, so prevention is not an option, so don’t overdo it when selecting.
Continuous harvesting and snatching of crops should be especially washed
Some short-term crops, such as cabbage, beans, melons are continuously growing harvestable, these fruits and vegetables will continue to grow new fruits, so regardless of harvestable, immature fruits, will be attached to the pesticide, to pay special attention when buying.
Another elephant is the typhoon season, the rainy season before and after the harvest of crops, farmers in order to reduce losses or fight for good prices, may ignore the safe harvesting period, resulting in more pesticide residues. In case of typhoon season, it is recommended that people buy less leafy vegetables and more root vegetables and fruits to avoid eating fruits and vegetables with excessive pesticide residues.
Safe harvesting period means that the pesticide spraying needs to be harvested after a certain period of time, the amount of pesticide that stays on the crop after harvesting, after cleaning, is safe for public consumption without doubt.
Many farmers avoid losses and therefore may rush to harvest fruits and vegetables around the typhoon season, when washing should be more thorough.
