This research used mango flavored kefir since this products was the top demand by consumer among kefir flavored products that was produced in this manufacture. Kefir from manufacture was transferred to laboratory using container box to provide buffer in the temperature decrease. As result, total yeast in mango flavored kefir was 1,21±0,06x105 CFU/ml. This total yeast was in the range of the Standard Codex 243-2003 which required a minimum total of 104 CFU/ml.
