Six months. Putting bamboo shoots in the freezer for a long time will easily affect the taste and quality, and it is best not to exceed 6 months. Bamboo shoots can be preserved for a longer time after drying. Peel and wash fresh bamboo shoots, then cook them with salt water, control the moisture and dry them in the sun. Be careful not to bask for too long, so as not to affect the taste. Sun-dried bamboo shoots can be kept in the refrigerator for half a year.
