What happens to cabbage when it freezes?
When cabbage freezes, the cell walls of the plant are damaged, which can affect its texture and quality. The water inside the cells of the cabbage turns into ice, causing the cell walls to rupture. This can lead to a softer, more limp texture, and a less crunchy bite. The flavor and nutritional content of the cabbage may also be affected, as some of the natural enzymes in the plant can break down, resulting in a less fresh taste.
The extent of the damage to the cabbage depends on the temperature and duration of the freezing. If the cabbage is only lightly frosted, it may still be usable, but if it has been frozen solid for an extended period, it may be too damaged to use. It’s also important to note that some types of cabbage, such as napa or savoy, may be more susceptible to freezing damage than others, like green or red cabbage. In general, it’s best to use frozen cabbage in cooked dishes, where the texture and flavor changes will be less noticeable.
