Jellyfish have been eaten for more than 1,000 years,with jellyfish salad a popular delicacy.Not only are they high in
protein,but the microalgae (inside the cells of some jellyfish are rich in fatty acids.
However,despite their appeal to adventurous Western diners,jellyfish are not a straight substitution for fish,or
other sources of protein.For one thing,jellyfish are 95%water,with the remaining 5%containing the nutritious
essentials.Their nutrition to mass proportions means they're a fairly inefficient source of protein."There is probably
more functional in them as a type of collagen(胶原蛋白)rather than protein,”says Jonathan Houghton,.a senior
lecturer in marine biology."But certainly not as a replacement for fish,as that is several orders of magnitude greater
as a potential food source."There are a number of companies already using jellyfish as a substitute for cow and pig
collagen,which is often used in medical treatments for humans.One British company says collagen from jellyfish
offers a better alternative,because their collagen is in harmony with a wide variety of human cell types.
