“…One hypothesis proposes that mushiness is due to proteolytic activity of the hepato pancreas in the tail muscle (Baranowski, Nip, & Moy, 1984;Lindner, Angel, Weinberg, & Granit, 1989;Lindner et al, 1988;Nip, Zeidan, & Moy, 1981), resulting in the degradation of prawn muscle (Nip et al, 1985;Kimura & Tanaka, 1986). Hepatopancreas extracts contain both peptidase and proteinase activity, and include aminopeptidase, carboxypeptidases A and B, cathepsin C, chymotrypsin, and collagenases (Garcia-Carreno, Hernandez-Cortes, & Haard, 1994).…”
