Embodiment 1
[0033] This embodiment provides a milk product processing method, comprising the following steps:
[0034] (1) Take fresh milk, preheat it to 30°C, and then filter it with two layers of gauze to get raw milk after filtering out impurities;
[0035] (2) Centrifugal defatting the raw milk described in step (1) at a speed of 65 r / min to obtain skim milk with a fat content of 0.7 wt %;
[0036] (3) Sterilize the skim milk described in step (2), and the sterilization process is divided into three stages, specifically: the first stage, heat preservation at 73°C for 25min; the second stage, heat preservation at 80°C 20min; in the third stage, keep warm at 88°C for 15min;
[0037] After the sterilization treatment is completed, the temperature is rapidly lowered to 38°C to obtain unfermented milk;
[0038] (4) Add a leavening agent to the milk to be fermented in step (3), and mix well, and the starter agent accounts for 0.5% by mass of the milk to be fermented, and then ferment at 3...
Embodiment 2
[0047] This embodiment provides a milk product processing method, comprising the following steps:
[0048] (1) Take fresh milk, first preheat it to 40°C, and then filter it with 4 layers of gauze to get raw milk after filtering out impurities;
[0049] (2) centrifuging the raw milk described in step (1) at a speed of 75 r / min to obtain skim milk with a fat content of 0.6 wt %;
[0050] (3) Sterilize the skim milk described in step (2), and the sterilization process is divided into three stages, specifically: the first stage, heat preservation at 74°C for 20 minutes; the second stage, heat preservation at 86°C 15min; in the third stage, keep warm at 96°C for 5min;
[0051] After the sterilization treatment is completed, the temperature is rapidly lowered to 42°C to obtain fermented milk;
[0052](4) Add a starter to the milk to be fermented in step (3), mix well and evenly, the starter is 1% by mass of the milk to be fermented, and then ferment at 45°C for 8 hours to obtain a...
Embodiment 3
[0061] This embodiment provides a milk product processing method, comprising the following steps:
[0062] (1) Take fresh milk, preheat it to 35°C, and then filter it with 3 layers of gauze to get raw milk after filtering out impurities;
[0063] (2) Centrifugal defatting the raw milk described in step (1) at a speed of 70 r / min to obtain skim milk with a fat content of 0.5 wt %;
[0064] (3) The skim milk described in step (2) is sterilized, and the sterilizing treatment is divided into three stages, specifically: the first stage, heat preservation at 73.5°C for 22min; the second stage, heat preservation at 82°C 18min; in the third stage, keep warm at 92°C for 10min;
[0065] After the sterilization treatment is completed, the temperature is rapidly lowered to 40°C to obtain fermented milk;
[0066] (4) Add a leavening agent to the milk to be fermented in step (3), and mix well, the mass percentage of the leavening agent in the milk to be fermented is 0.8%, and then ferment...
