    Density Relative
AI Thread Summary
Milk with a higher relative density is often considered better due to its increased total solids or total dissolved solids, which can enhance nutritional value. Higher density typically indicates lower fat content in non-homogenized full-fat milk, where cream rises to the top. For a given percentage of butterfat, a higher concentration of solids is advantageous. The use of a hydrometer is common for measuring these total solids, which are increasingly utilized in processed foods and contribute to better nutrition in powdered milk. The discussion highlights the importance of defining "better" in the context of milk quality, as it can vary based on specific nutritional goals or preferences.

Why is milk with a higher relative density better than one with a lower one.
 
Physics news on Phys.org
it depends on your measure of better. Higher butter-fat content perhaps?

In non-homogenised full-fat milk, the "cream" rises to the top. This implies denser milk has less fat.
 
You want a higher density of "Total Solids" or "Total Dissolved Solids". Those are going to have the effect of increasing the density of the milk fluid. For a given percentage of butter fat, more solids are better.

Mind you, I'm no expert. I was barely paying attention to that part of the spiel the one time I toured a dairy operation. Google says that a hydrometer is used to measure total solids.

Could you define what you mean by 'better'?

I'm not sure General Discussion is where this thread belongs, but I need to know what you're asking before I can move it to a more suitable place.

Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
