The present invention relates to a method for producing fermented milk, skim milk, or more specifically, mixed in a pre-heated oil a mixture of skim milk powder, and lactic acid proliferator, then homogenized, sterilized and cooled, by mixing the compound with lactic acid bacteria and bifidobacteria in a fermentation optimal fermentation conditions, lactic acid bacteria and bifidus bacteria in fermented milk than conventional fermented milk produced by the production method relates to the increase are capable of inducing the proliferation of the flavor and texture of fermented milk improved lactic acid bacteria and bifidobacteria, fermented milk preparation. fermented milk production method according to the present invention, preheating a crude mixture skim milk or skim milk, a lactic acid bacteria growth and the mixture is mixed to prepare a mixed flow oil manufacturing process (first step) and homogenization step of homogenizing the mixed oil of the first step (second step) and the second sterilizing the homogenized mixture of the process oil, which cooling sterilization and cooling step (the third step) and sterilization of the third step, the cooled mixture and the oil complex lactic acid fermentation to fermentation by Bifidobacterium mixing step (fourth step) and rough curd the fermentation process of the fourth step a pulverizing step of pulverizing curd mixture liquid (the fifth step) Homogeneous and the fermentation broth subjected to the milling process of the fifth process, including homogeneous and a cooling step for cooling the fermentation broth (the sixth step), characterized by comprising a.본 발명은 발효유제조방법에 관한 것으로서, 더욱 상세하게는 예열한 원유에 혼합탈지분유 또는 탈지분유, 및 유산균증식제를 혼합하여, 균질후, 살균 및 냉각하고, 복합유산균과 비피더스균을 혼합하여 최적의 발효조건에서 발효함으로써, 기존의 발효유 제조방식으로 제조된 발효유에 비해 유산균과 비피더스균수가 증가되어 발효유의 풍미와 식감이 향상된 유산균 및 비피더스균수의 증식을 유도할 수 있는, 발효유 제조방법에 관한 것이다. 본 발명에 의한 발효유 제조방법은,예열한 원유에 혼합탈지분유 또는 탈지분유, 및 유산균증식제를 혼합하여 혼합유로 제조하는 혼합유 제조공정(제1공정)과상기 제1공정의 혼합유를 균질화하는 균질화 공정(제2공정)과상기 제2공정의 균질화된
