Microencapsulated Lemongrass (Cymbopogon flexuosus) Essential Oil Supplementation on Quality and Stability of Silver Catfish Fillets during Frozen Storage

ABSTRACT: This research aimed to evaluate whether the essential oil of Aloysia triphylla (EOAT) used in vivo as a sedative in the water for transporting fish could increase the oxidative stability of silver catfish (Rhamdia quelen) fillets during frozen storage. The chemical composition of EOAT and of fillets from fish exposed to EOAT (0, 30 or 40µL L-1) were assessed. The pH and lipid oxidation parameters (conjugated dienes, CD; thiobarbituric acid-reactive-substances, TBARS) were evaluated in the fillets throughout the storage period (-18±2oC/17 months). The main compounds found in EOAT were α- and β-citral. Treatment with EOAT did not modify the proximate composition of the fillets, but 40µL L-1 EOAT reduced pH levels when compared to the control fillets (P<0.05). Compared to the control fillets, the fillets from fish treated with 30 and 40µL L-1 EOAT had higher initial CD values (P<0.05), whereas fillets from fish treated with 40µL L-1 EOAT had lower TBARS levels after 6, 9 and 17 months of storage (P<0.05). Results indicated that use of EOAT as a sedative in silver catfish transport water delays the degradation of primary oxidation products (CD) into secondary products (TBARS) in the frozen fillets. This delay in the lipid oxidation rate may increase the shelf life of frozen fillets.

RESUMO:The effects of anesthesia with the essential oil of Ocimum gratissimum (EOO) in parameters of stress after handling were investigated in silver catfish (Rhamdia quelen). EOO was obtained from the aerial parts by hydrodistillation. Juveniles were anesthetized with 70 or 300 mg L-1 EOO and submitted to air exposure for 1 minute. The fishes were sampled immediately or transferred to anesthetic-free aquaria until sampling. In the first experiment, juveniles had their blood collected at 0, 1, 4, and 8 h after handling to assay plasma cortisol and blood glucose levels. The unanesthetized animals were restrained manually for blood collection. In the second experiment, water samples of the recovery aquaria were collected to evaluate net ion fluxes at 0 - 4 h and 4 - 8 h. Water and ethanol controls were also performed under the same conditions. The results showed that the cortisol levels did not differ among the treatments. Hyperglycemia was verified in fish exposed to 70 and 300 mg L-1 EOO at 1 h and 4 h after handling. After 8 h, cortisol and glucose concentrations were lower or similar than those from immediately after handling for all treatments. EOO anesthesia prevented Na+ efflux observed in the control groups in both flux periods. There were net Cl- and K+ effluxes at 0 - 4 h and influxes at 4 - 8 h after handling in most treatments, and these fluxes did not differ among the treatments. The results suggest that EOO did not impair stress recovery and did not act as an additional handling stressor in silver catfish.
