Can raisins be stored in the refrigerator?

As a popular snack, raisins have rich nutritional value and can promote health for the human body. Because raisins have a relatively high sugar content, they basically do not require preservatives to maintain freshness. Of course, if you want the raisins to taste better, you can store them in an environment of 7 to 12 degrees. Here I will introduce to you the storage methods of raisins.

1. How to store raisins

The high sugar content of raisins allows them to remain fresh without the need for any preservatives. In addition, if raisins are refrigerated, their flavor, color and nutritional value can be maintained for up to fifteen months.

The quality of raisins will not be affected by refrigeration; they will soften quickly at room temperature. As long as the raisins are stored in a sealed bottle, they will remain fresh and soft, and retain their original moisture to prevent humid air from entering, and fructose will not crystallize on the surface of the raisins. Finally, remember not to store raisins near brick and stone walls because they will absorb moisture from the brick walls.

2. Storage tips for raisins

We all know that raisins have very high nutritional value. Moreover, raisins are made through natural drying. The finished raisins not only contain a large amount of glucose, vitamins and substances, but also contain a certain amount of water. So it tastes especially good. In order to keep raisins having a good taste, the preservation of raisins is very important. So, in real life, how should raisins be preserved?

1. It is very important to control the humidity of raisins

Through the nutritional analysis of raisins, it can be seen that raisins themselves generally contain about 15%-18% water, and the relative humidity of raisins is about 50%. If raisins are affected by the relative humidity of the outside world and the water content increases by two or three points, some crystals will form on the surface of the raisins. Although these crystals do not affect the taste of the raisins, their appearance is much inferior.

2. The storage of raisins requires a suitable temperature

Generally speaking, if you want to keep the original taste of raisins, the best storage temperature is 7-12℃ or lower. Only under such temperature conditions can raisins be preserved for a longer time.

3. It is best to keep the opened raisins in the refrigerator

Some people take some time to eat all the raisins after opening the bag, so if they want to maintain the original taste of the raisins, they should store them in the refrigerator. This is the only way to keep the raisins in their original state.

4. The storage environment of raisins must not be higher than 26℃

If raisins are stored in an environment above 26°C, due to the high storage temperature, it is particularly easy for termites to breed in the raisins after a period of time.

3. How to keep raisins fresh and prevent insects

Raisins are a great product for replenishing blood and qi. They are rich in iron and calcium, which are very beneficial to the human body. It also has the effect of lowering blood cholesterol, preventing cell deterioration, and inhibiting the growth of malignant tumors. However, its fructose content is as high as 60%, and it is easy to get infested with insects when stored. Using white wine can not only effectively prevent insects, but also make the raisins emit a light wine aroma.

1. Refrigeration: refrigerator, freezer, cold storage (reduces oxidation and various reactions).

2. Sealing: You can seal it with plastic film and extract the air (mainly to isolate water and oxygen and reduce the respiration and oxidation of the fruit).

3. Drying: desiccant, dehumidification facilities and equipment (to reduce water respiration and chemical reactions).

4. Avoid light: Use opaque packaging
