Every dairy in India lives and dies by two numbers. SNF and FAT. They appear on lab reports, they set the price farmers are paid, and they are the closest thing milk has to a report card. Yet almost no consumer knows what they mean. Let us fix that.
FAT: the richness number
FAT is exactly what it sounds like, the percentage of fat in the milk. It carries a lot of the flavour, the creaminess and the fat-soluble vitamins like A and D.
- Cow milk typically runs about 3.5 to 4.5 percent fat.
- Buffalo milk is richer, often 6 percent or more, which is why it tastes heavier.
Higher is not automatically better, it depends on what you want, but a fat figure well below the normal range can be a sign milk has been watered down.
SNF: the quality number
SNF stands for Solids-Not-Fat. It is everything solid in milk apart from the fat, the proteins, the lactose, the vitamins and the minerals. If FAT is the richness, SNF is much of the nutrition.
- Cow milk SNF is commonly around 8.5 percent or higher.
- A low SNF often points to dilution or poor-quality milk.
Because water lowers both numbers, SNF and FAT together are one of the first things a lab looks at to catch adulteration.
Why these two numbers protect you
Think of SNF and FAT as milk’s vital signs. Read together they tell you whether milk is rich, nutritious and undiluted, or thin and tampered with. That is why FSSAI sets minimum standards for both, and why serious dairies test every batch. Learn how in how milk quality testing works.
Seeing your own numbers
Here is the part most brands skip: showing you the actual figures for the milk you bought. PYAAS puts a QR code on every pack that opens that batch’s real SNF and FAT results, not a generic average, not a year-old certificate. It is the difference between being told milk is good and being able to read the proof.
Next time you pick up a pack, look for these two numbers. Once you know what SNF and FAT mean, you are no longer guessing about your milk, you are reading it.

Common questions
What does FAT mean in milk?
FAT is the percentage of milk fat, which carries much of the richness, flavour and fat-soluble nutrients. Cow milk typically ranges from around 3.5 to 4.5 percent fat, and buffalo milk is higher.
What does SNF mean in milk?
SNF stands for Solids-Not-Fat, everything solid in milk except the fat: proteins, lactose, vitamins and minerals. For cow milk it is commonly around 8.5 percent or above, and it is a key indicator of overall milk quality and whether milk has been diluted.
What are good SNF and FAT values for cow milk?
As a rough guide, cow milk with FAT around 3.5 to 4.5 percent and SNF around 8.5 percent or higher is considered good quality. FSSAI sets minimum standards, and PYAAS shows the actual tested values for each batch.
