Why does the perceived intensity of sweetness from a sugar substitute like sucralose diminish more rapidly over time compared to sucrose during prolonged tasting?

💡 Explanation

The perceived sweetness diminishes differently because the differential receptor binding kinetics cause sucralose to dissociate from sweet taste receptors at a faster rate than sucrose does. Therefore, the signal fades more quickly with sucralose, rather than uniform desensitization or neural adaptation affecting sucrose alone.
