The aim of this study was to investigate the viability of Pediococcus acidilactici ATCC 8042 and Lactobacillus plantarum ATCC 8014 in a freeze-dried capsules system prepared with sodium alginate and gum arabic using the extrusion technique. The capsules made with alginate 2% (w/v)/gum arabic 2% (w/v) showed higher hardness (7.12 ± 0.71 N), with highly cohesive (0.81 ± 0.02) and elastic (0.99 ± 0.00) features on the Texture Profile Analysis (TPA), as well as higher sphericity with 1.75 ± 0.12 mm y 1.73 ± 0.13 mm diameter axes and regularity in their surface by Scanning Electron Microscopy (SEM). The use of skimmed milk at 10% as a cryoprotector in the freeze-drying process allowed the obtention of high viability percentages (88% a 96%) for both strains. Best results of viability for P. acidilactici encapsulated was with the use of alginate 2% (w/v)/gum arabic 2% (w/v) (92%±2.65), and L. plantarum with the use of alginate 2% (w/v) (84.71%±10.33) during the gastrointestinal environment challenge.

这项研究的目的是研究在用藻酸钠和阿拉伯胶制备的冻干胶囊系统中，挤压法生产嗜酸乳球菌ATCC 8042和植物乳杆菌ATCC 8014的可行性。用2％（w / v）海藻酸盐/ 2％（w / v）阿拉伯胶制成的胶囊显示出较高的硬度（7.12±0.71 N），在其上具有高内聚性（0.81±0.02）和弹性（0.99±0.00）。纹理轮廓分析（TPA）以及直径为1.75±0.12 mm y轴为1.73±0.13 mm的更高球形度以及通过扫描电子显微镜（SEM）获得的表面规则性。在冷冻干燥过程中使用10％的脱脂牛奶作为防冻剂，可确保两种菌株均具有较高的存活率（88％至96％）。最佳的可行性结果用2％的藻酸盐（w / v）/阿拉伯胶2％（w / v）（92％±2.65）包被乳酸假单胞菌，以及使用2％的藻酸盐（w / v）的植物乳杆菌。 （84.71％±10.33）在胃肠道环境挑战中。
