| Abstract The main aim of this study was to investigate the
effect of alginate coating without or with lycopene at levels
of 0.5, 1, 1.5, and 3% on the quality of rainbow trout stored
under refrigerated conditions for 16 days. Samples coated
with alginate with or without lycopene showed significantly
lower free fatty acid (FFA) and total volatile basic nitrogen
(TVB-N) values compared to uncoated (control) filets,
particularly after day 4. Moreover, significant differences
(p\0.05) were observed between the coated samples
containing lycopene and samples not containing lycopene
on the last day. In relation with pH, none of the treatments
resulted in significant differences. In regard to oxidation
parameters, the effect of alginate-lycopene coatings was
only seen on day 16 of storage. In general, although alginate-lycopene
coating had no significant effect on the
reduction of thiobarbituric acid and peroxide values, it
succeeded in decreasing the TVB-N and FFA values. |
