D-Allulose (D-Psicose) vs. Granulated White Sugar (Sucrose)
Comparing 2 standards across 10 specifications. 10 key differences identified.
D-Allulose is a rare ketohexose monosaccharide that occurs naturally in figs and raisins. It delivers 70% the sweetness of sucrose with only 0.4 kcal/g (90% fewer calories than sugar), 0 glycemic index, and caramelizes identically to table sugar.
Granulated table sugar is 99.9% pure crystallized sucrose (disaccharide of 50% glucose + 50% fructose). It serves as the universal reference benchmark for relative sweetness (Sweetness = 100). Per 100g, it provides 387 kcal, 100g carbohydrates (0g fiber), and a glycemic index of 65.
