Effect of nanocomposite clay/low-density polyethylene film on the quality of rainbow trout (oncorhynchus mykiss) fillets stored with four different packaging conditions
MetadataShow full item record
Abstract: To improve the quality and increase the shelf life of rainbow trout fillets, nanocomposite clay/low-density polyethylene films were used during 25 days of refrigerated storage (4 °C). Low-density polyethylene (LDPE) films with 5 wt% clay nanoparticles (sodium montmorillonite, MMT) were used for packaging of rainbow trout fillets using 4 different packaging conditions (modified atmosphere packaging (MAP): 60 N2, 35 CO2, and 5% O2; vacuum packaging (VP); air packaging (AP); and control). Fish samples were analyzed on the first day and every 5 days to determine the extent of microbial deterioration, chemical changes, and sensory properties. Based on obtained results, the shelf life of rainbow trout fillets was determined as ~10 days for the control group, and 15, 20, and 25 days for the AP, VP, and MAP packages, respectively.
