# F42 vs F55 HFCS for carbonated soft drinks: how do you pick the blend?

Sweetness, mouthfeel and cost all shift with the fructose level. We are interested in how formulators choose.

- Which blend do you use for cola-style drinks, and why?
- Do you adjust the ratio for low-calorie or reduced-sugar versions?
- Have you seen a taste difference that buyers actually picked up on?

Curious whether anyone blends F42 and F55 on site rather than buying a single grade.
