In both indexes (TVB and TMA), the behaviour is similar until 7-10 day,
from which the lots that do not contain green tea extract in their film formulation presented an exponential rise of the amine volatile concentration.
This fact was consistent with the lessening of H2S-producing bacteria and luminescent colonies, which were also observed from day 10.
Thus, green tea film seems to be the cause of the reduced levels of TVB-N and TMA-N, caused mainly by
the delayed or reduced growth of bacteria such us S. putrefaciens and P. phosphoreum, which are involved in the production of basic compounds (TVB-N and TMA-N) in fish
