Method for preparing streptococcus thermophilus ATCC 14485 and aloe co-fermented beverage

The invention relates to a method for preparing a streptococcus thermophilus ATCC 14485 and aloe co-fermented beverage. The method is characterized in that natural aloe barbadensis juice and streptococcus thermophilus ATCC 14485 are subjected to co-fermentation, and the optimal fermentation conditions are determined through setting different temperature gradients and pH gradients and carrying out viable counting. Through assaying oxidation resisting indexes, such as DPPH free radical scavenging ability, iron ion chelating ability and total reducing power, of aloe probiotic fermentation liquor, the oxidation resistance of the aloe probiotic fermentation liquor is preliminarily determined and is evaluated, so that the development of aloe lotions and aloe drinks is realized.
