Grapes soaked in water spoil fast or not soaked in water spoiled quickly

Of course, it is more likely to break if it is soaked in water.

One, grape and microbial reproduction:

After the grapes are picked, they are still attached to the stalks, and at this time, there is no obvious damage, and under normal circumstances, they can be stored for 3 to a week without rotting. However, if the grapes are soaked in water after harvesting, it will cause the grapes to rot and deteriorate, because the water in the stalk and the stalk of the grape fruit is not easy to volatilize, and as long as there is a small wound, yeast and bacteria will take advantage of the weakness and infect the fruit.

Grape fruit is very high in sugar, water is also relatively abundant, for the natural microorganisms, is an excellent natural medium, as long as the grape has a little wound, yeast and bacteria will get the substrate for reproduction, at the right temperature, 12 hours will cause the grape berry to spoil.

Second, why do grapes go bad?

Many people like to put the grapes one by one after buying grapes, and then clean, the intention is good, but after cleaning you need to eat it immediately, if you want to leave it overnight or more than 12 hours, it will cause the pulp to deteriorate. On the stalk and flesh of the grapes, you will see white mucus, and there will be a sour and rancid smell, which means that it has lost its edible value.

Three: The correct way to preserve grapes is:

After buying the grapes, take off the packaging bag, even if there is a fruiting body protective bag during the cultivation process, take it off, put it in a cool and ventilated place, or place it in the fresh-keeping layer of the refrigerator, and wash it one by one when eating, so that bacteria and yeast will not be given a chance to multiply. It is also safe to eat.

I think it must have broken quickly.

Grapes will spoil if soaked in water overnight. Put the grapes one by one in a basin of water, don't completely remove the stems and leave a little, add water that can cover the height of the grapes, sprinkle some flour into the water (any type of flour, convenience stores are the easiest to obtain), stir a few times in the water with the palm of your hand, pour out the cloudy flour dirty water, and rinse it with water several times until the water is clear.

After washing, even if you put it in the refrigerator, you can only keep it for two or three days.

As long as the stems are not removed, the grapes will not rot easily without any damage.

The main causes of food spoilage:

1. Microorganisms play a role. Microorganisms are everywhere in the environment, and food is easily contaminated by microorganisms during production, processing, transportation, storage, and marketing.

2. Chemical reactions of food.

Fats are easily oxidized, resulting in a series of chemical reactions, and the oxidized fats have a strange smell, such as fat meat will turn from white to yellow.

Food deterioration: Food deterioration: refers to the physical change of food to change the appearance, as well as the spoilage and deterioration that occurs under the action of microorganisms.

3.Refrigerate: Place the grapes on a plate, do not wash.

4.Then put it in the refrigerator freezer, the temperature is not too low, generally about 0, can be stored.
