1. First, rinse continuously with running tap water for several minutes to remove most germs, pesticides and other pollutants on the strawberry surface. Note: Don't soak in water first, so as to avoid pesticides being absorbed by strawberries and infiltrating into fruits after being dissolved in water.

2. Soak strawberries in rice washing water (used for the first time) and light salt water (a pot of water and half a spoonful of salt) for 3 minutes. Their functions are different. Alkaline rice washing water can decompose pesticides. Light salt water can make insects and eggs attached to strawberry surface float, which is easily washed away by water and has a certain disinfection effect.

It can also be disinfected with 1: 5000- 10000 potassium permanganate solution (reddish), but it will become manganese dioxide and remain on strawberries. Although manganese is a component of many enzymes in the body and a trace element needed by the human body, the amount of manganese in the food we eat every day can meet the needs of the human body, so there is no need to supplement it.

3. Wash rice washing water, brackish water and possible residual harmful substances with flowing tap water.

4. Rinse with clear water (or cold boiled water).

Extended data:

Don't remove the stalks before washing strawberries, so as to avoid pesticides and pollutants infiltrating into the fruit through the "wound" during soaking, which will cause pollution instead; It is best not to use any cleaning agent including "vegetable cleaner" to clean strawberries.

Although all kinds of approved "food detergents" have passed the safety test and can be used to clean tableware and vegetables, the premise is that they should be cleaned at last, because detergents are all chemical products, after all, they are not food, and may remain on the surface of strawberries, which is difficult to clean, so it is better not to use them. It is best to eat as little chemically active substances as possible.
