Study of the performance of nisin supported in edible films

The antimicrobial activity of nisin supported in edible films prepared with suspensions of tapioca starch containing glycerol, was studied. Films were prepared by casting the systems after gelatinization. The effect of the edible film as antimicrobial barrier to external hazard as well as the diffus...
