Why do winter bamboo shoots put a few days soft?

Probably lost water.

Winter bamboo shoots themselves contain a lot of water, for fresh winter bamboo shoots, its texture is generally relatively crisp, but if the time is too long, then the water contained in winter bamboo shoots will be slowly volatilized.

At this time, winter bamboo shoots will not only become soft and taste but also easily breed microbes. Therefore, for fresh winter bamboo shoots, it is best to eat them while they are fresh, which is the best from the perspective of taste and nutrition.
