Chitosan for antimicrobial packaging -

The method ISO was used to compare the antibacterial effect of different chitosan-containing films when they were tested against the same volume of bacteria, with a known contact area between the bacteria solution and the active film. This method had a lot of elements affecting the results, and also many uncertainties.

The method was unstable, giving results that were invalid according to the standard. However, there seemed to be some antibacterial effect from the chitosan-containing films. coli, log 3. Against S. In order to gain more reliable results, a method was used where chitosan was tested in a liquid bacteria solution.

Here, a clear effect was found against both of the tested bacteria; E. coli decreased below the detection limit after five days and S. aureus after six days for the samples containing most of the chitosan film.

The results from incubation with chitosan powder were similar to those from testing of the film, but the bacterial counts decreased below the detection limit earlier in the incubation. coli counts were below the detection limit after four days, and S. These results strengthens the theory that chitosan is less available inside a rigid film structure than it is in the form of chitosan powder.

As the results from the liquid tests were promising, chitosan colloid was tested by comparison of growth curves with and without chitosan. The chitosan powder was solved in acetic acid, and this solution was then tested against the aforementioned bacteria by reading absorbance in bacteria solutions during incubation.

A antimicrobiao effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservation, chitosan films are very effective. Chitosan has widely been used in antimicrobial films, to provide edible protective coating, dipping and spraying for the food products due to its antimicrobial properties. Chitosan can be formed into fibers, films, gels, sponges, beads or nanoparticles.

: Chitosan for antimicrobial packaging

Access this article	In order to gain more reliable results, a method was used where chitosan was tested in a liquid bacteria solution. Here, a clear effect was found against both of the tested bacteria; E. coli decreased below the detection limit after five days and S. aureus after six days for the samples containing most of the chitosan film. The results from incubation with chitosan powder were similar to those from testing of the film, but the bacterial counts decreased below the detection limit earlier in the incubation. coli counts were below the detection limit after four days, and S. These results strengthens the theory that chitosan is less available inside a rigid film structure than it is in the form of chitosan powder. As the results from the liquid tests were promising, chitosan colloid was tested by comparison of growth curves with and without chitosan. The chitosan powder was solved in acetic acid, and this solution was then tested against the aforementioned bacteria by reading absorbance in bacteria solutions during incubation. The data was used to make growth curves, which made it possible to compare the bacterial growth between samples with and without chitosan. The acid tolerance of the bacteria became very limiting for the experiments, but at acid concentrations of 0. However, the effect might not be caused by the chitosan alone, but rather of a combination of chitosan together with the lowered pH. The reason of testing the chitosan films and powder was to see if chitosan-containing packaging materials could be used on foods to enhance food safety. Because some of the test methods gave good results, an experiment was conducted on smoked salmon. This was a storage experiment, and sampling was performed during storage for 41 days. This shows that the bacteria in the fish samples grew despite the presence of chitosan, which can be caused by the chitosan not being available for the bacteria, but it can also be that the trays should have had a higher chitosan concentration.
