The correct method for cleaning grapes

To properly clean grapes, first rinse the surface dust with running water, then soak in light salt water or edible alkali water for 10 minutes to remove pesticide residues, and finally rinse twice with clean water. Grape skins are prone to residual dust, pesticides, and fruit wax. Direct consumption may irritate the gastrointestinal tract or cause allergies, and thorough cleaning is necessary. The surface of grapes often adheres to particles such as dust and pollen, and washing with running water can remove most of the physical pollutants. When washing, it is recommended to place the whole bunch of grapes in a leaky basin and repeatedly rinse the gaps with flowing water to avoid direct rubbing that may cause damage to the skin. If the grape stem turns black or the fruit visibly softens, it may have spoiled and the inedible parts should be removed. Some grapes may use pesticides such as Bordeaux mixture during cultivation, and diluted salt water can decompose organic phosphorus pesticide residues. Dissolve 5 grams of salt in 500 milliliters of water, soak the grapes for 10 minutes, and gently stir to allow the insect eggs hidden in the fruit stem to surface. Edible alkali water is suitable for removing fat soluble pesticide residues, but excessive concentration can damage fruit powder. It is recommended to add 2 grams of edible alkali per liter of water and soak for no more than 15 minutes.

After cleaning, the grapes should be drained of water before consumption to avoid diluting the flavor with residual water stains. When storing, it is recommended to wrap it in kitchen paper and refrigerate it. It should be consumed within 2 days. Those with weak digestive function can eat grapes without skins. diabetes patients need to control the single intake of less than 15 grapes. If white crystals are found on the surface of grapes, they are mostly natural fructose precipitation, and washing them does not affect food safety.
