Granulated White Sugar (Sucrose)

Sugars & Alternative Sweeteners · 9 specs

Direct Answer

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.

Sucrose as the Global Reference Standard

All nutritive and non-nutritive sweeteners are calibrated against sucrose's relative sweetness index of 100. Sucrose provides bulking volume, moisture retention (hygroscopicity), and Maillard/caramelization browning in culinary baking.
