Enhanced Asian sea bass skin defatting using porcine lipase with the aid of pulsed electric field pretreatment and vacuum impregnation

Abstract

Abstract Lipid removal of Asian sea bass skin pretreated with pulsed electric field (PEF) at 24\u202fkV/cm for 72\u202fms, followed by hydrolysis with porcine pancreas lipase (PPL) at 42.36 U/g skin dry matter with the aid of vacuum impregnation (VI) at various vacuum times (10, 15, 20 and 30\u202fmin) was investigated. The highest lipid reduction in PEF-treated skin was found at vacuum time of 20\u202fmin (p
