Abstract

Background and Objectives: Fresh fruit juice is one of the best drinks which have minerals and vitamins and is a good source for water compensation, but if microbial quality of the fruit juice does not meet the standard level, it can be play as a source for food disease infections.
Material and method:In his cross-sectional study, all of 58 fruit juice shops in Bandar Abbas were selected as study population, correspondence rate was 84 percent. The samples were tested for total Coliform, Escherichia coli, Staphylococcus aureus, yeasts and molds.
Results:Testing the samples showed among 146 samples, 142 of them were contaminated by microorganisms. All of Carrot and mango juices were contaminated. The mean contamination rate of juices to Coliform bacteria, Mesophilic bacteria, Escherichia coli and yeasts were 86.2, 53.2, 57 and 56.6 percents respectively.
Conclusion:97.3 percents of samples did not have a good microbial quality for human consumption. If consumption of fresh fruit juices will cause the consumer at risk of food borne diseases, all the natural benefits of them in terms of richness in minerals and vitamins will waste.

Abstract
Background and Objective: Patulin is one of the most important mycotoxins produced by a wide range of molds. The main source of this mycotoxin is rotten fruits, especially apple juice. Patulin may damage the liver, spleen, and kidneys and cause seizures, edema, intestinal inflammation, and vomiting. Patulin may also have genotoxic and neurotoxic properties and disrupt the functioning of the immune and nervous systems.
Materials and Methods: In this study, the concentration of patulin in 34 random samples of fruit juice, including 26 apple juice samples, 4 apple and banana mixed juice samples, 2 apple and kiwi mixed juice samples, and 2 pomegranate juice samples sold in stores in Tehran in May 2024, was measured and reported using the HPLC-UV method.
Results: The LOD and LOQ levels were 1.21 and 3.49 µg/kg, respectively, and the recovery percentage was between 91 and 97 percent. The mean and standard deviation of patulin concentration in a total of 34 samples was 13.425 ± 21.348 µg/kg, which was below the permissible limit of the Iranian standard and Codex (50 µg/kg), and only the findings related to one of the samples were higher than the standard limit (14.88 µg/kg).
Conclusion: The results of this study show that the levels of patulin in the samples examined are mostly within the limits of Iranian and Codex standards. However, more comprehensive studies with a larger number of samples are recommended for a more accurate assessment of potential risks.
