 Erythritol (CAS NO.149-32-6) is often combined with the cooling effect of mint flavors, because it has a strong cooling effect when it dissolves in water. And beyond high intensity sweeteners, erythritol is also often paired with other bulky ingredients which exhibit sugar-like characteristics to better mimic the texture and mouthfeel of sucrose.
