Abstract

Neutral protease was seeked in carp and red sea bream muscles. Activity was determined by measuring Folin, Cu-Folin, and Ninhydrin values of the trichloroacetic acid filtrate of the reaction mixture. Optimum pH for casein hydrolysis at near neutral pH was recognizable at around 5.4 by each determination, but this activity was considered to be due to the usual cathepsin D. The hydrolysis of hemoglobin at neutral pH range was observed only by the Ninhydrin method and its optimum pH was near 7.0. This activity is considered to be a new protease in fish muscle which has not yet been reported.
