Effect of freeze-drying on the viability of selected probiotic organisms is shown in Table 1. Freeze drying had a deleterious effect on the viability of all probiotic organisms. In general, Bifidobacterium spp. had 7% higher survival than Lactobacillus spp. with the exception of B. longum 1941.
with 3% cells spray dried either with MDX (81.9% ) or NFSM (85.7%). Key probiotic properties like pH. tolerance, bile tolerance, antimicrobial activity and cholesterol assimilation behavior were found to be retained. to a significant extent after freeze and spray drying. The present study highlights that freeze drying and spray. drying of L. fermentum with MDX as a carrier may be a cost effective way of producing large quantities of. stable preparations retaining functional properties for nutraceutical application.
