Sucralose is a highly heat-stable artificial sweetener, allowing it to be used in many recipes with little or no sugar. It is available in a granulated form that allows for same-volume substitution with sugar. This mix of granulated sucralose includes fillers, all of which rapidly dissolve in liquids. While the granulated sucralose provides apparent volume-for-volume sweetness, the texture in baked products may be noticeably different. Sucralose is not hygroscopic, meaning it does not attract moisture, which can lead to baked goods that are noticeably drier and manifesting a less dense texture than those made with sucrose. Unlike sucrose, which melts when baked at high temperatures, sucralose maintains its granular structure when subjected to dry, high heat (e.g., in a 350 °F or 180 °C oven). Furthermore, in its pure state, sucralose begins to decompose into other substances at temperatures above 119 °C or 246 °F.[17] Thus, in some baking recipes, such as crème brûlée, which require sugar sprinkled on top to partially or fully melt and crystallize, substituting sucralose will not result in the same surface texture, crispness, or crystalline structure.
