The invention discloses yoghurt
powder with relatively high
viable count and a preparation method thereof, and relates to the technical field of
viable count yoghurt
powder. The milk beverage comprises
sterilized milk, activated bacterial liquid,
cane sugar and microcapsule
system components, the microcapsule
system comprises a
sodium alginate solution and a
calcium chloride solution; and inoculating the
sterilized milk into the activated bacterial liquid to obtain the fermented milk. According to the yoghurt
powder with the high
viable count, a traditional technology is matched with a microcapsule technology, yoghurt
protein and a
sodium alginate /
calcium chloride system are selected as wall materials of microcapsules, and the activity of
lactic acid bacteria is kept to the maximum extent through
centrifugation and low-temperature
drying (40 DEG C); the
survival rate of
lactic acid bacteria in the
processing and storage period is greatly improved, meanwhile, the penetrating power of
gastric acid and intestinal
mucus is enhanced, the intestinal
survival rate is remarkably improved, and then the yoghurt powder with the high viable count is obtained.
