How to wash grapes

First, put the grapes in water, then add 2 spoons of flour. You don't need to rub them hard at this time, just stir them back and forth 4-5 times to make the water white and turbid, and then the grapes can be cleaned. This is because the flour is very sticky and can remove bacteria and impurities on the grapes. In addition, you can also try adding vinegar, salt, or starch to clean the grapes.

How to preserve fresh grapes

Fresh grapes can be stored by wrapping them in newspapers and placing them in a cool place. They can usually be stored for about 3 days. You can also seal them in a fresh-keeping bag and store them in the refrigerator. This method can keep them for a longer time, about a week. If you have fruit and vegetable preservatives, you can spray them on the grapes and seal them in the refrigerator to effectively extend the storage time. It should be noted that fresh grapes cannot be washed before storage. Once washed, they will easily go bad. You should wait until you need to eat them before washing. Because grapes themselves contain high sugar and water content, they will rot and deteriorate if left at room temperature for too long, so it is recommended to eat them as soon as possible.

How long can grapes be kept?

Under normal temperature, grapes can generally be stored for about 3 days. However, due to the high sugar and water content of grapes, it is very easy to attract mosquitoes and insects when stored at room temperature, which will then breed bacteria and cause the grapes to deteriorate. Therefore, it is best to store uneaten grapes in the refrigerator to avoid affecting the taste and quality of the grapes. Under normal circumstances, grapes can be stored in the refrigerator for about a week.

Can I still eat grapes if they have white hair on their stems?

Grapes with white hairs on their stems should not be eaten, because the white hairs grow when the stems come into contact with spoiled substances. At this time, the grapes on the stems have also grown mold. If you continue to eat them, you may suffer from diarrhea, abdominal pain, etc. Also, be careful not to eat seafood or white radish when eating grapes, so as not to irritate the stomach and intestines, causing diarrhea and affecting your health.
