The present invention relates to a process for producing infant formulas and more particularly to the preparation of sterile constant temperature melting the raw material in water to prepare a liquid preparation, and after low temperature sensitive colostrum mixed with the raw material to heat denaturation of the oils and fats to minimize thermal degradation, and this prepared solution and the mixture homogenized by microbiological stability of the temperature is maintained at least by sterilization by, the effectiveness of the manufacturing process oil component, which may be modified in the raw material and the raw colostrum (sIgA, IgG, etc.) relates to a method for manufacturing a formula for infants that can maintain the activity of the. Infant formula according to the production method for the present invention, Protein raw material sources, carbohydrate sources raw, liquid preparation for dissolving the water-soluble vitamin and mineral in water to prepare a manufacturing process (first step) and Dissolving the raw material oils and fats at a constant temperature fats melting step (second step) and Colostrum of dispersing the second material by putting the raw material in the melted oils and fats colostrum dispersing step of the process a third step) and The third step of the mixture and mixing and homogenization by mixing the first step for homogenizing the mixture prepared in the step (fourth step) and Sterilization process for sterilizing homogeneous preparation solution in the fourth step (fifth step) And Comprises a spray-drying step of spray-drying the sterilized solution prepared in the fifth step (sixth step) and is characterized in that said.본 발명은 영유아용 조제유 제조공정에 관한 것으로서, 더욱 상세하게는 살균된 일정온도의 조제용수에 원료를 용해하여 조제액을 제조하고, 열 변성에 민감한 초유원료를 낮은 온도의 유지류와 혼합하여 열 변성을 최소화한 후, 이를 조제액과 혼합 및 균질하여 미생물적 안정성이 유지되는 최소의 온도로 살균함으로써, 제조공정 중 변성될 수 있는 유원료 및 초유원료의 유효성 성분들 (sIgA, IgG 등)의 활성을 유지할 수 있는 영유아용 조제유 제조방법에 관한 것이다.본 발명에 의한 영유아용 조제유 제조방법은,단백질 급원원료, 탄수화물 급원원료, 수용성 비타민 및 미네랄
