Doodh mein SNF kya hota hai? (SNF Full Form & Meaning)
SNF ka full form hai "Solids-Not-Fat" (Fat ke bina bache hue solid tatva).
Doodh mein 2 main parts hote hain: Paani (~85%–88%) aur Total Solids (~12%–15%).
- FAT: Doodh mein natural butterfat / chiknai.
- SNF (Solids-Not-Fat): Fat nikaalne ke baad bache hue saare nutritious elements jaise Protein (Casein), Lactose (natural sugar), Calcium aur Minerals.
``
Total Solids (TS) = FAT % + SNF %

Lactometer se SNF Kaise Calculate Karein? (Richmond Formula)
Dairy aur collection center par Lactometer Reading (CLR) aur FAT test karke standard Richmond Formula se SNF nikala jaata hai:
`
SNF % = (CLR / 4) + (0.21 * FAT %) + 0.36
``
Example Calculation:
- Measured CLR: 28 (at 27°C)
- Measured FAT: 4.0%
- SNF = (28 / 4) + (0.21 * 4.0) + 0.36 = 7.0 + 0.84 + 0.36 = 8.20%
