2, the shelf life of the cake is generally 2 days, the appropriate refrigeration temperature is 2-7 ℃. Cake can not be stored in the refrigerator for a long time, the longer the storage time, the more bacteria, the worse the taste, the color is not good. Some cakes have a shorter shelf life, like mousse cake, cheese cake refrigeration time is best not more than 1 day.

3, different cake preservation is different, if it is a chocolate cake, it is recommended to be placed in a cool place away from light, the temperature of 15-18 degrees Celsius to save, placed in the temperature is too high or too low, the chocolate may melt again crystallization, the formation of unsettled crystalline form, produce frosting, appearance and taste will be worse.

4. If the cake is a fruit cake with fresh fruit on the surface, it is recommended to eat it on the same day, not overnight, as the fruit may precipitate water or rot if left for too long.

5, if it is a mousse cake, remember to repeatedly frozen preservation, thawed and then frozen mousse will produce ice residue, very affect the taste. At the same time, the cake in the refrigerator to save, remember to do a good job of sealing treatment, otherwise it is very easy to string flavor, this is something to pay attention to. I tested the cake put frozen can keep how long, found that the cake this thing into the refrigerator inside the freezer can also be, so that you can keep it fresh, but also can not keep a very long time, almost to keep to two or three days or so, the cream of these cakes will deteriorate, because of the cream of this thing it itself is easy to deteriorate, so we must eat it as soon as possible.
