1)
The same yam powder products as in Table 1.
2)
Cd, cadmium; Pb, lead.
3)
Heavy metal food standard level: Korea, Cd and Pb level for root and tuber crops (20); EU, Cd and Pb for root and tuber crops (21); Codex, Cd and P levels for root and tuber vegetables (22).
Values of Korea, EU and Codex standard levelsare from food contaminants division in Food Safety Evaluation Department of Korea Institute of Food and Drug Safety Evaluation.
Values are two separates experiments performed in duplicates (mean±SD).
