140
Q

Why is the specific gravity of an emulsion important to a beverage?

Does it have to be close to the specific gravity of the final product?

A

It determines if it will be stable in a beverage. If the specific gravity is too far from water it can cause the emulsion to break which can cause ringing in a beverage.

Yes, it needs to match the final product.
