The effects of chitosan (Ch) and Ch combined with sodium tripolyphosphate
nanoparticles (Nch) as a coating material for Carangoides coeruleopinnatus fillets
during refrigerated storage were investigated. Solutions containing Ch (2%, w/v) and
Nch (with 2%, w/v Ch and 2% sodium tripolyphosphate) were used for the coating.
Coated and non-coated fish (control samples) with Ch and Nch were analyzed for
microbiological (total mesophilic and psychrotrophic count), physicochemical (total
volatile basic nitrogen (TVB-N), pH, trimethylamine (TMA), 2-thiobarbituric acid
reactive substances (TBARS), free fatty acid (FFA), sulfhydryl (SH)) and sensory
attributes. Among the edible coatings, Nch was most effective in controlling lipid
oxidation and reducing bacteria count in C. coeruleopinnatus during refrigerated
storage. Corresponding maximum levels of total mesophilic count at 4ºC were 5.11,
4.77 and 4.37 log cfu/g in control, Ch and Nch samples, respectively, while maximum
levels of psychrophilic count count at 4ºC were 4.43, 3.91 and 3.89 log cfu/g,
respectively. Nano-chitosan can be used for preservation of quality properties of fish
samples. The study showed that Nch could be used as a packaging material.
