FAQs

Why are sea cucumbers so expensive? 

Steven Purcell explains the demand for seafood has increased. The more they harvest, the rarer they become. They’re like luxury seafood that people want to pack in ornate boxes and give to each other on special occasions. 

The dried sea cucumber is more expensive, which makes sense because sea cucumbers are 95% water body. When they drain water, what is left is hollow flesh. So you need a good amount, like 5 to 8 kg of fresh sea cucumbers, to make a 1 kg dried sea cucumber. 

How long does sea cucumber last in the freezer?

Dry sea cucumbers can be stored in your pantry for up to 3 years. As for the frozen ones, they can last for 24 months in the freezer.
