Yoghurt beverage with added bacterial celluloses and method for preparing yoghurt beverage

The invention provides yoghurt beverage with added bacterial celluloses and a method for preparing the yoghurt beverage. The bacterial celluloses are added into fermented milk to obtain the yoghurt beverage, and the additive amount of the bacterial celluloses accounts for 2%-6% of the mass of the fermented milk; complex stabilizers are further added into the fermented milk, and the additive amountof the complex stabilizers accounts for 0.2%-0.7% of the mass of the fermented milk. The method includes carrying out activated culture and fermentation on gluconacetobacter xylinus to obtain bacterial cellulose fermentation liquor; taking out bacterial cellulose membranes on upper layers of the liquor level of the bacterial cellulose fermentation liquor to obtain the bacterial celluloses; homogenating the bacterial celluloses to obtain flocculent bacterial celluloses; adding the flocculent bacterial celluloses into intermediate milk, adding the complex stabilizers into the intermediate milkand carrying out homogeniz
