Abstract

Many brands produced fruit juices in different packaging like plastic bags, glass bottles and tetra packs to control the post harvesting loss. Some brands do not follow the rules and regulations regarding food quality and produce products harmful to human health. The current study was also based on examining and observing the tetra pack apple juices to check the food quality assurance and their physicochemical parameters. Moisture contents, ash, acidity, organic and inorganic content, crude fibers, pH, vitamin C, and carbohydrates by method reported in AACC and AOAC methods. The percentage of Moisture was highest as compare to the standard parameters in samples II, IV, VI, and VIII, (96.38%, 94.42%, 93.45%and 92.64%). The ash content was ranged from (0.05-0.12%). pH values high in samples IV, II, III. (3.70%,3.64%,3.22%,) while higher acidity was found in samples IV, VII, VIII, II (0.23%,0.20%,0.18%,0.15%), the pH and acidity were greater with compare to the standard values. Mostly protein contents were not in maximum range in juices while in our results maximum protein content was found in apple juice sample VII, (0.14%). Ascorbic acid was found higher from standard range in samples V, VIII, (11.8, 11.0mg/100g). All samples of apple juice have total sugars in a range of (6.2-10.2%), reducing sugars found in samples ranges of (2.7-5.3%), while non-reducing sugars were found in a range of (3.3-4.9%) which meet the standard range of tetra pack juices.
