Furthermore, in the first 9 days, no
significant difference in TMC and TPC values was observed between
lot Ch and lot Nch during the refrigerated storage (P > 0.05),
however, on day 12, TMC and TPC of fish treated with Nch were
significantly lower than that treated with Ch (P < 0.05), which could
be due to the higher antimicrobial activity of nanochitosan
compared to chitosan.
