The search for new technologies tha

The search for new technologies that guarantee the safety and quality of food has intensified, as has
concern for consumer health, leading to the adoption of measures to reduce food-related risks. The
purpose of the study was to evaluate the efficiency of active biodegradable films incorporated with
bacteriophage for future application in packaging materials. Cellulose acetate films incorporated with
solution of bacteriophages showed antimicrobial activity against Salmonella Typhimurium ATCC 14028
displayed the formation of inhibition zones in Muller-Hinton agar, and a growth curve, using the
diffusion method in liquid medium. There was an increase in the lag phase and slower growth of microorganisms
in the environment containing bacteriophages with the films, compared to control. The
mechanical and physical properties of films, such as thickness, elongation and puncture resistance
showed no significant effects. However, tensile resistance was different between control and treatments.
The addition of bacteriophage altered the film surface, as observed by atomic force microscopy. There
was a higher porosity of the films containing the bacteriophage solution compared to control. The acetate
films may be incorporated with bacteriophages, since the physical and mechanical properties of the films
were not changed drastically and there was an effect of the antimicrobial film.

Die soektog na nuwe tegnologie wat die veiligheid en gehalte van voedsel te waarborg het versterk, het as
verbruikers Kommer vir Gesondheid, wat lei tot die aanvaarding van maatreëls om Food-verwante risiko's te verminder. Die
doel van die studie was om die doeltreffendheid van 'n aktiewe bioafbreekbaar Films opgeneem met evalueer
bakteriofaag vir toekomstige toepassing in verpakkingsmateriaal. Films Ingelyf sellulose asetaat met
Oplossing van bakteriofage teen Salmonella Typhimurium ATCC 14028 Getoon aktiwiteit antimikrobiese
vertoon die vorming van inhibisie sones in Muller-Hinton agar, en 'n groeikurwe, met behulp van die
Diffusie metode in vloeibare medium. Daar was 'n toename in die stadiger groei van mikro-organismes en Fase LAG
in die omgewing met bakteriofage met die rolprente, in vergelyking met beheer. Die
meganiese en fisiese eienskappe van rolprente, soos dik, verlenging en lek weerstand
toon geen beduidende effekte. Maar trek weerstand was die verskil tussen beheer en behandelings.
Die byvoeging van bakteriofage Film Veranderde die oppervlak, soos waargeneem deur atoomkrag mikroskopie. Daar
was 'n hoër porositeit van die Films wat die bakteriofaag vergelyking met beheer Oplossing. Die asetaat
Films kan word gemeng met bakteriofage, aangesien die fisiese en meganiese eienskappe van die Films
nie drasties verander en daar was 'n effek van die antimikrobiese Film.
