Sucralose is classified as Limited under standard keto guidelines — pure sucralose contains 0g of carbohydrates, but sucralose products with maltodextrin bulking agents add carbohydrates that require monitoring.
Key Takeaways
- Sucralose is classified as Limited under standard keto guidelines.
- Pure sucralose (liquid form) contains 0g net carbohydrates per serving — classified as compliant.
- Sucralose packets with dextrose/maltodextrin contain ~1g carbohydrates per packet — acceptable in small quantities.
- Splenda baking blends containing sugar are not classified as compliant.
Classification Overview
Sucralose’s keto classification depends on the product form — pure sucralose versus sucralose combined with bulking agents.
Pure Sucralose
Pure liquid sucralose (sucralose-only liquid drops) and pure sucralose powder contain 0g of carbohydrates per serving. These products use only sucralose as the active sweetener ingredient without bulking agents. Published keto references classify pure sucralose products as compliant from a carbohydrate standpoint.
Sucralose Products with Maltodextrin (Splenda Granular)
Splenda yellow packets and granulated Splenda mix sucralose with dextrose or maltodextrin to provide bulk and flow properties. Each packet contains approximately 1g of carbohydrates from these fillers. At 1–3 packets per day, this contributes 1–3g of carbohydrates — generally manageable. For keto baking requiring many packets (cup-level quantities), the carbohydrate contribution from maltodextrin becomes significant.
Splenda Product Line Differentiation
- Splenda Liquid Drops: 0g carbs — compliant
- Splenda Individual Yellow Packets: ~1g carbs per packet from dextrose — Limited
- Splenda Granulated (pourable bag): contains dextrose — Limited, quantity-dependent
- Splenda Baking Blend (with sugar): contains sugar — not compliant
Comparison with Other Sweeteners
Stevia (pure leaf extract, liquid, or crystalline erythritol-based) contains 0g of carbohydrates and is classified as Allowed. Erythritol contains 0g net carbohydrates. Allulose contains 0g net carbohydrates. Sucralose in pure form is equally compliant; the commercial product form determines practical classification.
Summary
Sucralose is classified as Limited under standard keto guidelines. Pure sucralose in liquid or powder form contains 0g of carbohydrates and is classified as compliant. Commercial sucralose products mixed with dextrose or maltodextrin (such as Splenda granular packets) contain approximately 1g of carbohydrates per packet — manageable in small quantities but requiring attention in larger keto baking applications. Splenda baking blends containing sugar are not classified as compliant.
