Process for extraction preparation of active zinc metallothionein in sea cucumber and abalone

This invention belonging to metallothionin extraction field is about the extraction procedure of active zinc-sulfur protein from sea cucumber and abalone. The whole procedure involves feedstuff inducing, cleaning the raw material, squashing, filtering, homogenate, crystallization and extraction. With the procedure we reported here, most of sea cucumber and abalone'effective efficiency is remained, the purity of our product is up to 90%, and the procedure is easy to manipulate. We could extract 300g zinc-sulfur protein from 500g dried sea-cucumber or extract 300g active zinc-sulfur protein from 500g alive sea-cucumber.
