How long can yogurt be kept after opening

Usually, yogurt should be consumed immediately after opening, otherwise it will easily deteriorate. If it cannot be consumed on the same day, it must be stored in the refrigerator. If it is just kept indoors, it will go bad and the taste of the yogurt may become bad, for example, it may feel sour. In this case, it is best not to drink it.

If it is a yogurt drink, it can be kept at room temperature, but yogurt must be kept in the refrigerator! Even if placed in ice water, it can only be kept for about 1 day. It will not work if placed in cold water.

For more details, please refer to the following paragraph:

House-shaped yogurt is packaged in house-shaped cartons and refrigerated at 0-4°C. The shelf life is 7 days.

Cup yogurt is refrigerated at 2-6°C and has a shelf life of 14 days; bagged yogurt is refrigerated at 2-10°C and has a shelf life of 48 hours.

Yogurt drinks can be stored in a cool and dry place at room temperature and have a shelf life of up to 8 months.

Since yogurt does not contain preservatives, if the storage conditions are not good, the live lactic acid bacteria in the yogurt will continue to multiply, and the lactic acid produced will continue to increase the acidity, making the yogurt taste too sour. In severe cases, the yogurt will deteriorate. Therefore, when buying yogurt in summer, you should pay special attention to the storage environment of the yogurt. It is best not to buy yogurt that has been placed in a high temperature place for a long time.

Generally speaking, if the milk powder is not finished within about one month after opening (limited to bottled milk powder), do not give it to the baby. After opening, the contact with oxygen and some external environmental influences will affect the quality of the milk powder. Adults can eat milk powder that is more than 21 days old but less than 60 days old, but it is best not to eat milk powder that has been opened for more than two months. Some milk powder cans will have reminders on the back that they should not be given to babies within 30 days after opening. There are also markings on the milk powder, and mothers can also check it out.

Experts say that because infant formula is rich in nutrients and high in protein, the rich protein and nutrients are a breeding ground for bacterial growth and reproduction, and are also prone to attracting insects.

Consumers must be careful to preserve the milk powder after opening it. To avoid contamination and deterioration of milk powder, special attention should be paid to the fact that milk powder should not be stored in the refrigerator after opening. Because of repeated taking out and putting in, the temperature and humidity differences inside and outside the refrigerator can easily cause baby milk powder to deliquesce, clump and deteriorate. After opening, milk powder can usually be stored at room temperature, away from light, in a dry and cool place. After each use, the plastic cap of the canned milk powder must be tightly closed, and the bag of bagged milk powder must be tied tightly.

To facilitate the storage and removal of milk powder, after the bagged milk powder is opened, it is best to store it in a clean milk powder can. Wipe the milk powder can with a clean, dry cotton towel before use, and do not wash it with water. After the milk powder is opened, the prescribed usage time must be followed. Most baby formula packaging clearly states that the formula should be used within one month after opening. After opening, it should be discarded if it is used for more than one month.
