Probiotics are live microbes with beneficial effect to the host when administrated in adequate quantities. Ensuring the functionality of probiotics can be a challenge for manufacturers due to harsh environment conditions during processing, handling and storage. Enterococcus faecium IS-27526 is one of novel probiotic strain isolated from dadih, traditional fermented buffalo milk of West Sumatra. The purpose of this study was to determine the effect of microencapsulation, moisture absorber, and storage temperature on the half-life of probiotic powder estimated by Accelerated Shelf Life Testing (ASLT). There were two treatment groups, namely free cell (FC), and microencapsulated cell (EC), with additional treatment in each group, with addition of moisture absorber (MA) and without moisture absorber, stored at various temperatures (5°C, 27°C and 37°C) for 21 days and viable counts was assessed every 7 days. Storage temperature significantly affects the half-life of probiotic powder (p 0.05) at various temperature storage.
