2. Beneficial Bacteria in Milk (दूध में मौजूद लाभकारी बैक्टीरिया)

These bacteria are naturally present or added for fermentation and have health benefits.

Bacteria Name (बैक्टीरिया का नाम)Health Benefits (स्वास्थ्य लाभ)Use (उपयोग)
Lactobacillus (लैक्टोबैसिलस)Aids digestion, boosts immunity. (पाचन में सहायक, रोग प्रतिरोधक क्षमता बढ़ाता है)Yogurt, probiotic drinks (दही, प्रोबायोटिक पेय)
Bifidobacterium (बिफीडोबैक्टीरियम)Improves gut health. (आंतों के स्वास्थ्य में सुधार करता है)Fermented milk products (किण्वित दूध उत्पाद)
Streptococcus thermophilus (स्ट्रेप्टोकोकस थर्मोफिलस)Helps in lactose digestion. (लैक्टोज पचाने में मदद करता है)Cheese, yogurt (पनीर, दही)
Propionibacterium (प्रोपियोनिबैक्टीरियम)Produces Vitamin B12. (विटामिन B12 बनाता है)Swiss cheese production (स्विस पनीर उत्पादन)

3. How to Reduce Harmful Bacteria in Milk? (दूध में हानिकारक बैक्टीरिया को कैसे कम करें?)

✅ Pasteurization (पाश्चराइजेशन): Heat milk to a specific temperature to kill bacteria.
✅ Boiling (उबालना): Boil milk at 100°C for 2-3 minutes to destroy most bacteria.
✅ Proper Storage (उचित भंडारण): Keep milk refrigerated at 4°C or below.
✅ Hygiene (साफ-सफाई): Use clean containers and avoid contamination.

 Milk Plant Water Treatment Process Introduction Water is one of the most important raw materials in a milk plant. It is used for milk processing, equipment cleaning (CIP), boiler, cooling tower, floor washing, and staff hygiene . If water quality is poor, it directly affects milk quality, bacterial count, taste, shelf life, and plant hygiene . That is why proper water treatment system is mandatory in every milk plant. Why Water Treatment is Important in Milk Plant? ✔ Prevent milk contamination ✔ Maintain hygiene & food safety ✔ Protect equipment from scale & corrosion ✔ Meet FSSAI, ISO 22000, AGMARK standards ✔ Improve milk shelf life Sources of Water in Milk Plant Borewell water Municipal water Tanker water (temporary) ⚠️ Raw water cannot be used directly – treatment is compulsory. Milk Plant Water Treatment Process (Step by Step) 1️⃣ Raw Water Storage Tank Raw water collected in underground/overhead tank Tank should be: Cemented or ...

1. Mixing: Thorough Agitation: Before sampling, ensure the bulk tank's contents are thoroughly mixed to achieve homogeneity. This can be done by agitating the milk for about 5 minutes. 2. Sampling: Use of Clean Equipment: Always use clean, sanitized dippers or sterile syringes to collect milk samples. Sampling Location: Collect samples from the top of the bulk tank, avoiding the outlet, as milk from the outlet may be contaminated. Sample Volume: Fill the sample container halfway to allow for expansion during freezing. 3. Handling: Immediate Cooling: Place samples on ice or in a refrigerator immediately after collection. If testing cannot be performed within 24 hours, freeze the samples. Labeling: Clearly label each sample with relevant information, including date, time, and source, to ensure traceability.  1. मिश्रण: पूर्ण मिलाना: नमूना लेने से पहले, बल्क टैंक की सामग्री को अच्छी तरह से मिलाएं ताकि दूध समान हो जाए। इसके लिए लगभग 5 मिनट तक दूध को हिलाएं। 2. नमूना लेना: साफ उप...
