Product Overview
Erythritol (CAS 149-32-6) is a four-carbon sugar alcohol (polyol) produced through natural glucose fermentation. Present as a white crystalline powder, it offers approximately 70% of the sweetness of sucrose with near-zero caloric content. It exhibits high thermal stability, non-hygroscopic properties, and a clean cooling taste profile without residual bitterness.
