I see that the study uses 48mg sucralose in 60ml water amounting to 0.8g/liter.

My Cola recipe with pure sucralose uses 0.167g/liter this should be equivalent to normal soda sweetness of 100g sugar/liter.

The issue I had with sucralose was that it seemed to go out of solution in the syrup that’s why my current Cola recipe uses a mix of sucralose/saccharin/stevia in the ratio of 30/30/40 which amounts to 0.05g sucralose/liter so if I drink 1 liter of soda I’ll get the same amount as their study.

The reason I continue to use sucralose is that it rounds out the flavor of saccharin and stevia.
