Kefiran is a prebiotic polysaccharide produced by lactic acid bacteria with bifidogenic effect and immunomodulatory activity in vitro and in vivo. Whey proteins are extensively used on food products because of their high level of essential amino acids and their functional properties. Both macromolecules have capability to form edible films. The objective was to develop edible films from mixtures of kefiran and whey proteins as carriers for the administration of probiotic microorganisms. Combinations of whey proteins, kefiran and glycerol as plasticizer in formulations were assayed. Kluyveromyces marxianus CIDCA 8154 and Lactobacillus paracasei CIDCA 8339 were also included. Natural or forced convection, as dry methodologies, were used to obtain the films.
