1. How to preserve leftover grapes

1. Wash the grapes when you are about to eat them. They will easily go bad if you wash them before eating. After buying it, wrap it in paper (which can absorb some of the seeping juice and extend the shelf life) and put it in the refrigerator.

2. Be careful when buying, try not to buy bad ones, then remove the bad grains and debris, wash and drain, it is best to vacuum it, and put it in the constant temperature room of the refrigerator.

3. Don't rush to remove the branches and stems of the newly bought grapes, because removing the stems will cause the grape fruits to be exposed to the air, which will not only attract insects but also accelerate oxidation.

4. Seal with plastic wrap. Do not rinse the grapes, but put them directly in a plate and seal it with plastic wrap to prevent a lot of air from entering and slow down the oxidation process.

5. Refrigerate. If the grapes have been washed, they must be refrigerated to slow down the rate of deterioration as much as possible. The temperature should not be too low or too high, around zero degrees is fine.

6. Do not eat it soaked in water. When you rinse with water, there are a lot of air bubbles in the water. If the grapes are soaked in water for a long time, they are more likely to deteriorate.

7. Weigh 0.3% of the amount of stored grapes for sodium bisulfite and 0.6% of anhydrous silicic acid, mix them thoroughly, and pack them into several small paper bags. Put a layer of paper on the grapes, spread the medicine bags on the paper, and then seal the medicine bags with wrapping paper and put them in the storage warehouse inside the basket. The storage temperature should be 0-10℃ and the relative humidity should be 85%-95%. During storage, the storage quality, efficacy and phytotoxicity should be checked regularly.
