How long whipped cream can be preserved after opening is mainly related to its preservation environment. If the whipped cream is opened and placed in a refrigerator at 2-8 degrees Celsius, it can generally be kept for 3-7 days. The unopened fresh cream can be preserved for a long time, usually 2 months, if it is sealed with a fresh-keeping bag. The most suitable storage temperature of fresh cream is about 0 degrees.

The storage time of whipped cream after opening is relatively short, but it will be longer if some disinfection treatment is carried out. The specific method is as follows: when opening the whipped cream, fold a small corner and wipe it with an alcohol cotton ball for disinfection; Then cut a small hole, squeeze out the cream, pack the remaining whipped cream, exhaust the air inside, then wipe the periphery of the hole with alcohol cotton balls, and finally wrap the cut hole with tin foil, put it in a sealing clip and store it in a refrigerator at 2-8 degrees Celsius. According to this method, fresh cream can be stored for half a month to one month without deterioration. Although it can be preserved for such a long time, it is recommended to eat it as soon as possible after opening it.
