Occurrence and risk characterization of non-nutritive sweeteners in selected food products from Korea.

Non-nutritive sweeteners (NNS) are food additives that impart a sweet taste to food product with lower calories. Acesulfame potassium, aspartame, sodium saccharin, sucralose, steviol glycosides and enzymatically modified stevia are permitted in Korea. The study established the method of each NNS and applied it to each food items consumed in Korea. For risk assessments, the estimated daily intake (EDI) value for each NNS was calculated. EDI values of NNS were compared directly with each ADI (acceptable daily intake). The total estimated daily intake ranges by age compared with the % ADI were 0.12-0.53, 0.93-1.68, 0.05-0.20, 0.06-0.42 and 0.17-0.98% for acesulfame potassium, sodium saccharin, aspartame, sucralose and sum of stevioside and rebaudioside A, which were based on the overall averages. It can be concluded that the daily dietary intake of each of the five NNS is at a safe level when considered as a proportion of the ADI.
