Pediococcus pentosaceus P107 microencapsulated viability up to 7 days storage at − 20 °C during exposure to the simulated gastrointestinal tract. a Gastric fluid pH 2.0; b gastric fluid pH 2.5; c gastric fluid pH 3.0, both at times of 30, 60, and 120 min; d intestinal fluid pH 8.0 with 0.5% with bile salts and without, both by 240 min. ^a–cMeans ± standard deviation with different superscript letters indicates a lower significant difference between the microcapsules for the same time and pH (p < 0.05). ^A–CMeans ± standard deviation with different superscript capital letters denotes significant differences between the same microcapsule in the different analysis times for the same pH (p < 0.05). W, whey powder microcapsule; WX, whey powder with xanthan microcapsule; WP, whey powder with pectin microcapsule
