Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage
نویسندگان
چکیده
The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate freshness of Oncorhynchus mykiss fillets during 14 days at refrigerated temperature. 160 pieces fish enfolded in 4 types as main group-series. components carvacrol (83.2%) p-cymene (3.11%), thymol (2.13%) and γ-terpinene (1.63%). UV-Vis TEM evaluations S-AgNPs showed that size was mostly smaller than 55 nm diameter. Mesophilic psychrophilic bacteria counts remarkably less 6.0 log CFU/g about 2.1, 1.3 2.0, 1.0 CFU/g, respectively for samples wrapped S-AgNP/Ult.PVA (Ultrasound method) S-AgNP/Pho.PVA (Photochemical preserved °C on 7th day. strong efficiency complete eliminating S. aureus from coated trout E. coli mesophiles. It is suggested AgNP/Ult.PVA can be used nanocomposite film preservation temperature postpone spoilage up

Effect of packaging with nano-composite clay/LDPE film on the quality of rainbow trout (Oncorhynchus mykiss) fillet at refrigerated storage
In recent years, application of nanotechnology in the food packaging industry has become more widespread and is progressively being commercialized. Adding nano-materials improves polymers` barrier properties for gases such as O2 and Co2, and increases UV rays barrier, mechanical strength, stiffness, stability, and heat resistance of the base polymer. In this study, low density polyethylene film...

Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...
متن کاملImprovement of lipid stability of refrigerated rainbow trout (Oncorhynchus mykiss) fillets by pre-storage α-tocopherol acetate dipping treatment
One of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. This study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. Trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg(-1) flesh) and subsequently...
