Person Z (70 kg) wants to sweeten a 250 mL beverage that typically contains 10 g sucrose per serving using either Sweetener A (relative sweetness 250×, ADI 10 mg/kg) or Sweetener B (relative sweetness 1,000×, ADI 4 mg/kg). For each sweetener, determine the mg needed per serving and whether one serving would exceed that sweetener's per-day ADI for Person Z.

• A. You cannot calculate required mass without knowing the beverage temperature and pH because relative sweetness values are only valid under controlled laboratory sensory panel conditions.
• B. Sweetener A: 400 mg/serving; ADI 700 mg/day → one serving exceeds ADI. Sweetener B: 100 mg/serving; ADI 280 mg/day → one serving exceeds ADI in both cases.
• C. Sweetener A: 40 mg/serving; ADI 700 mg/day → one serving is safe. Sweetener B: 10 mg/serving; ADI 280 mg/day → one serving is safe.
• D. Sweetener A: 4 mg/serving; ADI 700 mg/day → one serving is unsafe. Sweetener B: 1 mg/serving; ADI 280 mg/day → one serving is unsafe because ADI only applies to aggregated weekly intake.

Answer: (C)
