ABSTRACT
Abstract The objective of this study was to evaluate the influence pH, bile salts and different storage conditions at two temperatures (30 4 °C) on viability free microencapsulated Lactobacillus paracasei . Microspheres encapsulating L. were obtained using an extrusion method. efficiency 87.6%, diameter 70 µm zeta potential 7.22 ± 0.05 mV. Encapsulated showed higher resistance stomach pH compared cells. evaluated under four conditions: fresh, suspended in a solution with 4, saline lyophilised. lyophilised microspheres presented highest stability 89.2% survival rate after six weeks storage; however, bacteria (0.145 N) 65.3% rate. Finally, new product (a strawberry ice popsicle) possible functional characteristics
