The effects of Zataria multiflora on inhibition of polyphenoloxidase and melanosis formation in shrimp (Litopenaeus vannamei) [PDF]

open access: yes, 2014
Shrimp melanosis (black spot) is an important surface discoloration caused by polyphenol oxidase (tyrosinase) enzyme, which oxidizes phenols and leads to insoluble black pigments, the melanins.

CHARACTERIZATION OF POLYPHENOLOXIDASE FROM WILD PEAR (PYRUS ELAEGRIFOLIA)

open access: yesJournal of Food Biochemistry, 2008
ABSTRACT Wild pear polyphenoloxidase (PePPO) was extracted and purified using a Sepharose 4B-l-tyrosine-p-amino benzoic acid affinity column. Optimum conditions for pH, temperature and heat inactivation were determined. At the optimum pH and temperature, KM and Vmax values for PePPO with catechol and pyrogallol were determined. The Vmax/KM showed that
