ABSTRACT
We report on the extraction of ß-chitin from pens (or Gladius) of Uroteuthis edulis, a squid species prevalent in the Pacific coastal regions of East Asia. In particular, we employ cryogenic mechanical grinding (or cryomilling) as a pre-treatment process for the raw squid pens. We show that the cryomilling step enables an effective pulverization of the raw materials, which facilitates the removal of protein residues allowing the extraction of high-purity ß-chitin with a high acetylation degree (â¼97 %) and crystallinity (â¼82 %). We also demonstrate that the Uroteuthis edulis extract ß-chitin affords a free-standing film with excellent optical transmittance and mechanical properties.
