Quality, sensory and microbial characteristics of fresh orange juice packed in LDPE nanocomposite films incorporating organoclay, modified nanoclays and Ag, Cu and ZnO nanoparticles

The aim of this research was to investigate the efficiency of LDPE films incorporating fifferent nanofillers in extending orange juice shelf life. Fresh orange juice packed in different films was assessed for microbial stability, ascorbic acid content, pH, color parameters and sensory quality during 0, 7, 28 and 58 d of storage. Mold and yeast growth, acidophil and aerobic mesophil bacteria populations in orange juice packed in nanocomposite films containing metallic nanoparticles were significantly (p
