The invention provides a process of preparing direct-acidified milk beverage keeping high viable cell count at ambient temperature. The process means that, adopting conventional technology to prepare acidified milk beverage and sterilizing, then adding Lactobacillus rhamnosus ATCC 53103 and certain quantity of growth promoting factors under aseptic condition. According to various pH value, the product can be stored at ambient temperature for 1-6 months and the viable cell count will not be less than 105 cfu/ml milk beverage. The indexes of storage period and viable cell count are much higher than fermented milk beverage prepared by conventional process. Thereby it overcomes the defects that direct-acidified milk beverage with long shelf life has no viable lactic acid bacteria and has low nutritional value.
