You can eat it. I saw on TV that the shelf life of food means that during this period, the quality, taste and taste of food are the same as the original. In addition, food has a shelf life, that is, the deadline for food preservation to not deteriorate, probably for a period of time after the shelf life (the shelf life of various foods is different). According to this meaning, I think sea cucumber is dry, and its shelf life should be longer, so it can be eaten. It is normal that the meat is not so tight.

For reference only.
