AbstractViability of bifidobacteria in freeze-dried probiotic products at various temperatures during prolonged storage was assessed. Bifidobacterium longum 1941 and B. longum 536 were freeze-dried and capsules were manufactured. Five commercial probiotic capsule products were also tested. The capsules were stored at -18°C, 4°C, and 20°C. Cell counts were enumerated using MRS-NNLP agar at 37°C for 72 h under anaerobic conditions at 0, 1, 2, 5, and 8 mo (commercial capsules) and at 0, 1, 2, 5, 8, 11, 14, 17, and 20 mo (laboratory capsules). Storage at 20°C showed the greatest decline in the viability of bifidobacteria, whereas that at -18°C showed the least decrease.
