Correct washing steps of cabbage:
(1) Removing outer leaves
The outermost leafy vegetables of cabbage are the most prone to pesticide residues, so it is best to pick off the outer leafy vegetables before cleaning.
(2) Stem removal
The stem is also the most prone to residual pesticides, and the stem must be partially removed before cleaning.
(3) flowing clean water washing
It is best to soak cabbage in water 10~20 minutes, and then rinse it with flowing water.
(4) Brush each leafy vegetable lightly.
After soaking and washing with flowing clean water, each leaf vegetable of cabbage can be lightly brushed with sponge cloth or soft brush, and the effect of removing residual pesticides is the best. Wash vegetable leaves with rice washing water, and wash cabbage with rice washing water to effectively remove toxicity, because rice washing water is alkaline and general pesticides are acidic, but make sure to use clean rice washing water.
The recipe for cabbage preservation:
1. Uncooked cabbage can be diluted with flour to paste and coated on the stem of cabbage, which can prolong the storage time because of absorbing flour nutrients.
2. Cover the stem coated with flour with a piece of kitchen paper towel or wet paper towel so that the flour will not touch the refrigerator or other items.
3. Cabbage can be stored in the refrigerator with the stem facing down and placed in the direction of cabbage growth, which can prolong the storage time.
Precautions for cabbage;
Do not wash cabbage with salt water.
Never use salt to clean cabbage. Salt will form a salt film on cabbage, just like a protective layer. In the cleaning process, clear water can't penetrate the protective layer and pesticide residues can't be removed.
When cooking vegetables, don't cover the pot, which will make the pesticides left on cabbage unable to evaporate.
