How long do you keep blueberries?

frozen storage can be kept for a long time.

Blueberries have high nutritional value and edible value, and are rich in vitamins, protein, cellulose and various mineral components. Generally, they are suitable for storage at room temperature of 18-26 C. When stored in small packages, they can be stored for about 3-5 days, but if the indoor storage temperature exceeds 28 C, they can only be stored for 2 days.

secondly, if it is stored in the refrigerator, it can help to inhibit the growth of bacteria and microorganisms in the refrigerator at low temperature, thus prolonging its shelf life. It can be stored for about 5-1 days in cold storage and up to about 1 month in frozen storage.

saving for too long is not recommended.

generally speaking, it is possible to store blueberries for three months as long as they are packed and then stored in the refrigerator, but it is usually not recommended to store them for three months. Because three months is a long time, even if blueberries do not go bad after a long time, the nutrients in them will be lost and the taste will be worse, thus reducing their nutritional value and edible value, so it is not recommended to store blueberries for three months.

tip: however, if the blueberry is made into jam and some food additives are added, in this case, the blueberry can be kept for about three months, but be careful not to open it, and it is best to eat it within one week after opening it.

Fresh blueberry fruits bought in supermarkets are usually packed in 125g plastic boxes. Before buying, the freshness of blueberries should be checked. The specific methods are as follows:

1. Check the amount of white fruit frost on the fruit surface, and the freshness of blueberries will be high, while the freshness of blueberries will be poor if there is little or no fruit frost;

2. Look at the bottom of the blueberry box. If pink liquid is found, it indicates that there are rotten fruits in the box. In high-end supermarkets in Japan, all fresh blueberries should be thrown away if they are not sold out that day. In Hong Kong supermarkets, the price of fresh fruit will be reduced by about 5% if it can't be sold on the same day. Therefore, the price of fresh fruit sold in supermarkets is related to freshness and does not represent the real market price.

Like many fruits, fresh blueberries should be compact, dry, plump and smooth. Generally speaking, blueberries don't have leaves and stems. Remember, the size of the head is not a sign of whether the blueberry fruit is ripe or not, but the color of the blueberry is very important. The fruit of ripe blueberries should be between deep purple and blue-black.
