Abstract: Microencapsulation provides a physical barrier to the Lactobacillus against the harsh environmental conditions and gastrointestinal passage thereby increasing the number of viable cells reaching the small intestine,and it is also beneficial to storage,processing and transportation.Spray drying is a common technology used in microencapsulation process because it is a continuous and rapid process with low cost and high reproducibility.However,it can cause a decrease in microorganism numbers and activity due to high inlet and exit air temperatures and evaporation rates during the process,which has strict requirement for Lactobacillus in the selection of wall materials and preparation parameters.This article reviewed the research progress of spray drying for microencapsulated Lactobacillus,which contained the selection of microcapsule wall material,technological parameter and the evaluation method of microencapsulated Lactobacillus.It could provide the theoretical basis of preparation for microencapsulated Lactobacillus and its industrial production.

Key words: spray drying; microencapsulation; spray dry; Lactobacillus
