<p>Microbial and physicochemical properties of seven branded, seal tampered refrigerated fruit juices were carried out in this study using standard methods. Coliform counts ranged from 2.079 to3.093 log<sub>10</sub>cfu/ml over the storage period with pineapple juice and citrus juice having the highest and least coliform count respectively. Total bacteria count in the juice ranged from 7.009 to 8.243 log<sub>10</sub>cfu/ml. Citrus fruit juice however had the highest staphylococcal count while pineapple juice had the least (2.344 to 3.881log<sub>10</sub>cfu/ml). Also, osmophilic yeast count ranged from 2.017 to 3.903log<sub>10</sub>cfu/ml, having the highest load in orange fruit juice and lowest load in citrus fruit juice. The pH of the juice samples ranged from 2.9 to 4.2 during the period of refrigeration. Conductivity was highest in apple fruit juice and lowest in orange nectar pulp fruit juice. The total dissolved solids ranged from 0.29 to 1.95 over storage and was recorded highest in apple juice and lowest in orange nectar pulp fruit juice. Turbidity ranged from 5.8-200. These results indicate a reduction in the quality of fruit juices after 5 days of opening and thus reveals that both spoilage and pathogenic organisms could proliferate in juices despite refrigeration.</p>

Apple Fruits

Apples represent a greater proportion of the worldwide fruit supply, due to their availability on the market and to the high number of existing cultivar varieties and apple-based products (fresh fruit, fruit juice, cider and crushed apples). Several studies on apple fruit metabolites are available, with most of them focusing on their healthy properties’ evaluation. In general, the metabolic profile of apple fruits strongly correlates with most of their peculiar characteristics, such as taste, flavor and color. At the same time, many bioactive molecules could be identified as markers of a specific apple variety. Therefore, a complete description of the analytical protocols commonly used for apple metabolites’ characterization and quantification could be useful for researchers involved in the identification of new phytochemical compounds from different apple varieties. This review describes the analytical methods published in the last ten years, in order to analyze the most important primary and secondary metabolites of Malus domestica fruits. In detail, this review gives an account of the spectrophotometric, chromatographic and mass spectrometric methods. A discussion on the quantitative and qualitative analytical shortcomings for the identification of sugars, fatty acids, polyphenols, organic acids, carotenoids and terpenes found in apple fruits is reported.
