In our daily life, you know the pesticide residues in vegetables and fruits. How can we get rid of them? Let's take a look.

Vegetables and fruits are essential for every family to have three meals a day. Vitamins in vegetables and fruits are very important to ensure our health. However, in order to prevent pests from attacking vegetables and fruits, pesticides are usually applied. Vegetable pesticides are mainly organophosphorus pesticides. Because organophosphorus pesticides are insoluble in water, only some contaminated pesticides can be removed by soaking and washing. Rinsing with clear water is the basic method to remove other pollutants and residual pesticides in vegetables and fruits. This method is mainly used for leafy vegetables, such as spinach, day lily, chives, lettuce and Chinese cabbage. Generally, the surface of vegetables is washed with clear water first, and only soaked in clear water for about 10 minutes. At the same time, the fruit and vegetable cleaning agent can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaning agent can be added when soaking vegetables with clear water. Rinse it with running water for two or three times after soaking.

Pesticides are mostly organophosphorus, which can be decomposed quickly in alkaline environment, so soaking in alkaline water can remove residual pesticides in fruits and vegetables. Cleaning fruits and vegetables with alkaline water requires a good concentration, and the best removal effect is to add 10% edible alkali to clean water. If the concentration of edible alkali is less than 2% or more than 15%, the effect is the same as tap water. Only part of the contaminated pesticides can be removed, but washing is the basic method to remove other pollutants and pesticides in vegetables and fruits. Generally, the surface dirt is washed off with clear water first, and then soaked in clear water for 20-30 minutes. Vegetables, common pesticides are organophosphorus pesticides, carbaryl and so on. Therefore, most vegetables are basically alkaline if they are cleaned. For example, soaking in 0.4% sodium bicarbonate for 10 minutes is usually useful. Organophosphorus pesticides decompose rapidly in alkaline environment. Soaking in alkaline water is an effective measure to remove pesticide pollution and can be applied to various vegetables and fruits. The specific operation is as follows: firstly, clean the dirt on the surface of vegetables with clear water, then soak it in alkaline water (generally adding 5- 10g alkali in 500ml water) for 5-15min, and then rinse it with clear water for 3-5 times.

Cleaning of Taomi water: Taomi water is weakly alkaline, which can cooperate with acidic pesticides, similar to edible alkali. Disadvantages: Some edible rice also has the problem of pesticide and egg residue, and there are uncertain risks. Put a bottle of baking soda in the family kitchen. The pesticides used in China are mainly organophosphorus, and most organophosphorus pesticides will slowly decompose or even fail when they encounter alkali. Organophosphorus pesticides will quickly decompose and fail in alkaline environment, and soaking in alkaline water is an effective measure to remove pesticide pollution. There are many fat-soluble pesticides. In addition, some fruits are preserved with wax. These can only be done with organic reagents. Alkalinity can be combined in some cases, and it will be effective if used at home. Please contact me if you have your own laboratory. I think we can basically ignore the common sterilizer.

Pesticides can be slowly decomposed into regular storage over time, reducing pesticide residues. Therefore, apple, kiwi fruit, wax gourd and other non-perishable varieties can be stored for more than 15 days. At the same time, benefit farmers. Bian Xiao advised not to eat freshly picked unpeeled fruit immediately. Pure natural deep-sea shell powder can also play an active role in purifying calcium ions by forging, which has the same effect as the surfactant added in detergent. Nano-scale (18000000 mesh) shell powder made by high-tech technology has strong permeability and the ability to decompose and neutralize harmful substances, such as Chinese cabbage, cabbage, cabbage and other vegetables, which can be broken into leaves by hand before eating. Pesticide residues on vegetables will slowly lose their effect when soaked in water.

After all this, I began to get to know you.
