Resumen:
In this work, an alternative matrix for probiotics delivery constituted by whey25 proteins and polysaccharide kefiran was investigated. Edible transparent and26 homogeneous films containing the microorganisms Lactobacillus paracasei CIDCA27 8339 and Kluyveromyces marxianus CIDCA 8154 with probiotic characteristics have28 been developed. Inclusion of microorganisms did not modify thickness, color or29 mechanical characteristics of films. This matrix showed good capability protecting the30 included probiotics from stress during film obtaining process and through31 gastrointestinal passage simulation. At the end of the applied gastrointestinal tractmodel, 7.1.105 CFU/cm2 K. marxianus CIDCA 8154 and 1.65.107 CFU/cm232 L.33 paracasei CIDCA 8339 remain viable, having decreased less than 0.6 logarithm cycle34 with respect to those originally included, even after 57 days of films storage.
