Table 2 Variations in concentration of trace metal in mg/kg wet weight of raw cassava, dried chips, and HQCF

From: Variations in trace metal and aflatoxin content during processing of High Quality Cassava Flour (HQCF)

Sample Cu Fe As Hg Pb Zn
Raw cassava 2.05 ± 0.18d 14.59 ± 0.23ab ND* <0.01a ND* 6.49 ± 0.06c
Dried chips 1.74 ± 0.26cd 16.37 ± 0.33c ND <0.01a ND 7.44 ± 0.06c
SDC-HQCF 1.36 ± 0.11ac 14.75 ± 0.65a ND <0.01a ND 9.28 ± 0.12a
MDC-HQCF 1.15 ± 0.21a 11.32 ± 0.01a ND <0.01a ND 5.50 ± 0.55b
  1. *ND means not detected. Limit of detection for As = 0.02 mg/kg and Pb = 0.1 mg/kg
  2. Results are presented as means ± standard deviation. Superscripts to figures in the same column implies significant or insignificant differences at p ≤ 0.05 (ANOVA, Duncan test)
