Vegetables and fruits Thanks to this guide, pesticide residues can be cleaned up and removed.

1. What types of pesticide residues can be found in fruits and vegetables?

Organophosphorus pesticides, organochlorine pesticides, carbamate pesticides, pyrethroid fertilizers, and so on can be classified based on their properties.

Acidic fertilizers, alkaline pesticides, and neutral fertilizers are classified according to their acidity.

Water-soluble fertilizers, fat-soluble water testing tds meter fertilizers, and so on can be classified based on their solubility.

Fertilizers are classified according to their efficacy as insecticides, acaricides, fungicides, herbicides, and so on.

2The Cleaning Principle

1Physical force elution: lifting abrasion physical contact elution according to cleaning.

2. Elution of solubility: direct melting followed by elution.

3Chemical reactive elution: high temperature decomposition after melting elution based on the acid-base reaction.

4, deterioration.

3. What methods are used to remove pesticide residues from fruits and vegetables?

1. washing method by immersion

Spinach, cabbage, and other leafy vegetables can be cleaned with edible alkali solution or rice wash water soak 5 minutes up and down, followed by a gentle hand wash, and then rinse with water; allow the case to be cleaned with water, or cleaned with an ultrasonic instrument, and then washed with flowing water.

2Heating technique

Beans, cauliflower, and other beans, as well as brassica vegetables, can be scalded for 1 minute up and down before cooking, allowing the fertilizer that is easily decomposed by heat to dissolve in the water and then rinsed with water.

3Lighting technique

Apples and other nuts and fruits should be placed in the sunlight for 5 minutes to allow the fruits and vegetables to decompose and effectively remove organophosphorus pesticides.

4, method of storage

East melon, pumpkin, and other melon vegetables can be treated a few days before consumption with ingredients from their own basic metabolism to break down a portion of the residual fertilizer.

5The peel method

Potatoes, cucumbers, apples, pears, and other fruits and vegetables with skin have the majority of their pesticide residues on the surface, and the peeling method can be very effective in removing the majority of their pesticide residues.

4What should I look out for when cleaning?

1. It is preferable not to destroy its structure before cleaning it.

After folding picking, do the first clean up in the cleaning process to effectively avoid the fertilizer in the clean-up time into the tissue inside. For example, hand-torn cabbage should be cleaned first after tearing it; strawberries should be cleaned first, and then the strawberry tips removed; and beans should be cleaned first after being whole, and then picked into small sections.

2. The longer the soak time for cleaning up, the better.

According to research, soaking time of 5-15 minutes on all types of fertilizer removal rate is more balanced. If soaking time is too long, fertilizer may be adsorbed in fruits and vegetables again.

3, when cleaning different types of fruits and vegetables, separate them as much as possible

Fruits and vegetables fertilizer are mostly attached to the surface, so pay attention to the different types of separation when cleaning. Cross-contamination may occur if the litchi and strawberries are cleaned together.

Why does water have a high TDS?

Elevated TDS has been linked in the US to naturally occurring environmental features like seawater intrusion, carbonate deposits, salt deposits, and mineral springs; however, other possible sources include road salts used for de-icing, anti-skid materials, chemicals used in drinking water treatment, stormwater runoff, and agricultural runoff.
