Generally, brown meat showed lower levels of TVB-N and TMA-
N thanmuscle throughout the study (Fig. 4). In the beginning of the
experiment, TVB-N and TMA-N values were higher in DR and LF
meat, thus suggesting higher level of degradation. The high initial
TVB-N and TMA-N values detected in all treatments can be due to
the presence of high quantities of free amino acids and nitrogenous
compounds in crustacean meat that render them susceptible to
rapid degradation by spoilage biota (Jay, Loessner, & Golden, 2005).
