How long the cream stays fresh in a gas cylinder (a storage container filled with disposable nitrogen dioxide gas) depends on several factors, including whether stabilizers are added, storage conditions and whether it is re-aerated.
It is recommended to use the whipped cream immediately, but if there is any leftover, it can be stored in the refrigerator for about 1 day. If you want your cream to last longer, add a stabilizer during the whipping process, such as gelatin, skimmed milk powder, cornstarch or instant pudding powder. Whipped cream this way will keep in the refrigerator for 3 to 4 days. If you want your cream to stay fresh longer, consider refilling your whipper with nitrogen dioxide gas, which will keep it in the refrigerator for up to 14 days.
It is also important to store leftover cream, whipped cream can be stored by placing a sieve over the bowl so that any liquid drips to the bottom of the bowl while the cream remains on top, maintaining optimal quality. At the same time, you should avoid using the last 10% of cream that contains a lot of liquid, which can lead to a decrease in cream quality.
Typically, homemade whipped cream will stay fresh for 1 day in a whipping machine, and whipped cream with a stabilizer can stay fresh for up to 4 days. In addition, cream can also be frozen and stored. Frozen cream can be squeezed into a specific shape and placed in the refrigerator until solid, then transferred to a sealed bag for storage and needs to be defrosted again before use.
Generally speaking, if no stabilizer is used, it is generally recommended to consume unopened whipped cream within 1 day. However, if a stabilizer is added, or the whipper is filled with nitrogen dioxide gas, the freshness time of the cream can be extended to 3-4 days or even 14 days. It should be noted that if the whipped cream is left in the refrigerator for longer than the recommended time, or if it becomes moldy, separates, or loses volume, it should no longer be used. Always check the quality before use to ensure there is no deterioration to ensure safety and health.
