SWEETENERSERYTHRITOL Natural low-calorie sweeteners Erythritol is a crystalline, white, anhydrous, non-hygroscopic solid that has very much the appearance of table sugar. Chemically, erythritol is (2R,3S)-butane-1,2,3,4-tetraol (Fig. 3.1), a linear, four-carbon polyol. It is non-reducing and, therefore, does not undergo Maillard browning.
