Title

QUALITY, SENSORY AND MICROBIAL CHARACTERISTICS OF FRESH ORANGE JUICE PACKED IN LDPE NANO COMPOSITE FILMS INCORPORATED WITH ORGANOCLAY, MODIFIED NANOCLAYS AND AG, CU AND ZNO NANOPARTICLES

Abstract

 The aim followed in this research was to investigate the efficiency of LDPE films incorporated with different Nano fillers in extending SHELF LIFE of ORANGE JUICE. Fresh ORANGE JUICE packed in different films was assessed for MICROBIAL stability, ascorbic acid content, pH, color parameters and sensory QUALITY following 1, 7, 28 and 58 days of storage. Mold and yeast, acidophil and aerobic mesophyll bacteria populations in ORANGE JUICE packed in NANO COMPOSITE FILMs containing metallic nanoparticles were significantly (p<0.05) lower than those packed in LDPE films containing Nano clay as well as those packed in pure LDPE films. LDPE with metallic nanoparticles exhibited the strongest antimicrobial effect after 28 days pas compared with the other films. The least ascorbic acid loss was seen in LDPE-modified organoclay films as compared with other NANO COMPOSITE FILMs; pH increased upon storage, the lowest being recorded in LDPE-metallic nanoparticles as compared with other treatments during different periods of storage. The overall color change (DE) and browning index (BI) of ORANGE JUICE packed in LDPE-metallic nanoparticle films were significantly (p<0.05) higher than those packed in LDPE-modified organoclay and then control films (pure LDPE). The highest and lowest overall sensory scores were obtained for ORANGE JUICE packed in LDPE-metallic nanoparticles and control films, respectively. According to the related standards, the migration of silver, copper and zinc ions from films coated with metallic nanoparticles were counted as lower than in their toxic limits.
