Concentration distribution of OTA.

Distribution of OTA level (μg/kg) no.
Samples	No. of positive/total samples	Positive(%)	<1	1 to 15	>15	Mean ± SD (μg/kg)	Range (μg/kg)
Turmeric	0/20	0	0 (0%)	2 (10%)	0 (0%)	1.07 ± 1.0	0.55–3.7
Red pepper	0/20	0	7 (35%)	4 (20%)	0 (0%)	1.52 ± 1.78	0.47–5.58
Black pepper	20/20	100	0 (0%)	0 (0%)	20 (100 %)	49.29 ± 48.4	15.91–197.64
Cinnamon	2/20	10	3 (15%)	10 (50%)	2 (10%)	18.5 ± 40.82	0.7–139.44

Note: samples are considered to be positive at OTA concentrations exceeding 15 μg/kg ().
