Three-step cleaning
Three tricks
Identifying "poisonous leeks"

Fresh leek leaf color
Fresh emerald green shiny,
Straight, thick leaves

3 steps
Many pesticides though in the natural environment
You can kill all sides

One fear of high temperatures
Two fears of alkaline water

Rinse with running water first
Mix baking soda (edible alkali) with water
Steep for 5 to 15 minutes
Studies show
Add 10% edible alkali to water
The removal of organophosphorus pesticide residues is the best
Too high and too low is not good
Therefore wash the fruits and vegetables with alkaline water
You need to master the concentration
furthermore
Washing fruits and vegetables with detergents is not recommended
Because detergents are chemicals themselves
May cause secondary pollution
3
Scalding inactivates the pesticides
This practice is mainly
Against carbamic acid insecticides
It breaks down faster as the temperature rises
So it can be placed in after cleaning
Boil in water for 2 to 5 minutes
Fish out immediately
