The analysis of Gasy and noneGasy Beverage's Caps in Tehran Province with Respect to microbial Load and Comparing them with Nano Antibacterial Caps

Technological achievements of today’s world have improved human being’s comfort while depreciated their tranquility. Apart from the nutritious complications which are currently concerned by the academic associations, another problem dealt with canned beverages is their quality 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 even chemical risks . These pollutants might enter consumers’ bodies in time of consumption. within this research, 150 canned fizzy beverages and metal can fruit, juices from the city Tehran were collected; (25 ones collected out of the supermarkets having fridge, 25 out of off-road wholesellers, 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 total count. The survey was done in 2 ways. First. The smeared swap was moved to the broth areas. In the second approach, the swap was taken to the broth inside.tripticase media And after 24 48 hours of incubation, 0.1ml of the sample was spread on the area. The numbers of fully grown colonies inside the sealed cans of fruit juices and fizzy beverages after the incubation were as follow : 4 colonies before opening the cans , 6 colonies on the edges of cans after consumption and 7 colonies on the edge of the can after consumption which totally demonstrate lack of a biding by the safety tips to the manufactured product after it gets out of the factory leading to poisoning the consumer after all . In the second phase of the research, the nano-antibacterial stopples to protect 25 other canned beverages added to the final product from the last factory’s packaging were used. They sensibly reduced the microbial load and made it reach to zero.
