This study determined nutrients, chemical contaminants, (insecticide residues and heavy metals), and natural toxic substances (nitrate, nitrite, cyanide, oxalate, phytate, and trypsin inhibitor) in tubers of Jerusalem artichokes-Kaentawan in the Thai language-grown in four major provinces in Thailand. They were purchased, prepared, homogenized, and freeze-dried for further analysis using standard methods. All Kaentawan samples contained considerable amounts of fructans and dietary fiber (15.4 +/- 0.2 g and 3.2 +/- 0.8 g/100 g fresh weight [FW], respectively), as well as potassium and iron (339 +/- 61 and 0.32 +/- 0.05 mg/100 g FW, respectively). All samples had very low amounts of insecticide residues (37 compounds), cyanide, and trypsin inhibitor, as well as Pb, Cd, nitrate, and nitrite (0.82 +/- 0.09, 0.10 +/- 0.02, 1.9-17.5, and 0.01-0.24 mg kg(-1) FW, respectively), in addition to oxalate and phytate (14 +/- 9 and 0.17 +/- 0.02 mg/100 g FW, respectively). This study's data can be used for food composition data-bases and for safety consumption. (C) 2016 Elsevier Ltd. All rights reserved.
