Microencapsulation of Lactobacillus acidophilus LA-5, Bifidobacterium animalis subsp. lactis BB-12 and Propionibacterium jensenii 702 by spray drying in goat's milk

Abstract

A mixture of probiotic Lactobacillus acidophilus LA-5, Bifidobacterium animalis subsp. lactis BB-12 and novel potential probiotic Propionibacterium jensenii 702 was resuspended in reconstituted (20% w/v) goat's milk, spray dried in a mini spray dryer (inlet temperature=195°C and outlet temperature=85°C) and the spray dried powder was stored in air tight glass jars at 4°C and 30°C for 24 weeks. Powder quality and probiotic viability after spray drying and subsequent storage were measured. Spray drying probiotics in reconstituted goat's milk resulted in a significant reduction in the viability of all three probiotics. However, all three probiotics were able to maintain satisfactory viability l..
