Questions About Utilizing Shrimp Shells

It's been a long time since I ate some shrimp. I want some astaxanthin and the best source I know and can find is shrimp, but if you know some other sources please add them here.

The question is, should shrimp exoskeletons or shells be utilized in food preparation at all or just thrown away ?

These studies make me wonder:







A warning comes about cadmium in the heads and the amino acid distribution of its protein may not be much desirable but it has astaxanthin, and also a significant amount of marine lipid and probably some other valuable components.

Whether chitin is beneficial seemed questionable to me:


Options of utilizing it that comes to my mind are:

1) Just cooking it in some liquid and throwing the solids

2) Pulverizing in a blender with some ingredients, cooking and eating

The lipids are fragile but astaxanthin may help to protect them while cooking, though whether long cooking times such as in a broth may be a good option is questionable, I guess...

If you (or anyone oyu know) grows tomatoes...shrimp shells (ground up) are great for suppressing nematodes... mix them in with the soil when you plant the seedings.

Shrimp stock is tasty. Not everything has to have a rationale in nutrition science though.
