There is a lot of sediment on the dried kelp, and there will be a layer of hoarfrost-like white powder. This white powder is not a mold or a dirty thing, but a nutrient-mannitol. It has the functions of lowering blood pressure, diuresis and detumescence. So don't wash it off!

How to clean quickly and healthily? Let me make a move.

Tools/raw materials

Dried kelp

Flour (or starch) 1 spoon

clean water

Methods/steps

1, dried kelp is put on the steamer drawer for dry steaming for 20-30 minutes;

2. Put the steamed kelp into clear water, add a spoonful of flour (or starch), and gently stir and soak for 10 minute. Note: Don't soak for too long! Otherwise, the nutrients of kelp (iodoacetic acid, mannitol, etc.) will be dissolved and lost.

3. After 10 minutes, gently rub the kelp with your hands, and you will find that all the sediment falls and the water is mixed and dirty. At this time, rinse it with water for several times. Then you can safely stew, stir-fry and cold salad!
