Why does sugar free soda fizz way more than regular soda?
In: Chemistry
The carbonation levels are the same. Sugar-free and sugar-based drinks have different foaming properties. You’ll notice that the bubbles in the foam on sugar-free drinks are bigger.
Different sweeteners mask the bitterness from the carbonated water (which is acidic) differently. This bitterness is important in the perceiving fizz. Sugar based drinks are also slightly more sticky (viscosity).
So, it is really the perception of fizz (mouth-feel) that is different and that’s in part due to the bubble size, stickiness, and taste.
