Abstract :

Technological achievements of today’s world have improved human being’s comfort whiledepreciated their tranquility. Apart from the nutritious complications which are currentlyconcerned by the academic associations, another problem dealt with canned beverages is theirquality control in time of exitting the production saloon and then packaging in the factory.through this phase, a safe product may be contaminated by microbial , physical and evenchemical risks . These pollutants might enter consumers’ bodies in time of consumption. withinthis research, 150 canned fizzy beverages and metal can fruit, juices from the city Tehran werecollected; (25 ones collected out of the supermarkets having fridge, 25 out of off-roadwholesellers, 50 out of the manufacturing plants and 50 out of the restaurants inside Tehran.)these samples were moved to the food microbiological laboratory for the microbial test and totalcount.The survey was done in 2 ways. First. The smeared swap was moved to the broth areas. In thesecond approach, the swap was taken to the broth inside.tripticase media And after 24-48 hoursof incubation, 0.1ml of the sample was spread on the area. The numbers of fully grown coloniesinside the sealed cans of fruit juices and fizzy beverages after the incubation were as follow : 4colonies before opening the cans , 6 colonies on the edges of cans after consumption and 7colonies on the edge of the can after consumption which totally demonstrate lack of a biding bythe safety tips to the manufactured product after it gets out of the factory leading to poisoningthe consumer after all .In the second phase of the research, the nano-antibacterial stopples to protect 25 other cannedbeverages added to the final product from the last factory’s packaging were used. They sensiblyreduced the microbial load and made it reach to zero.
