Arsenic concentrations were 0.40 ± 0.03 and 0.58 ± 0.12 mg/kg in parboiled rice of arsenic affected area, cooked with excess water and 1.35 ± 0.04 and 1.59 ± 0.07 mg/kg in gruel for BRRI dhan28 and BRRI hybrid dhan1, respectively. The analytical method was validated by measuring several parameters including limit of detection (LOD), limit of quantification (LOQ), linearity, relative bias, and repeatability. But the FDA has not set a limit on the amount of plain rice adults should eat. Using village-based rice processing plants in rural Bangladesh, this study considered how parboiling rice could be altered to reduce the content of the carcinogen inorganic arsenic. 8 Our experience is that total arsenic can be reduced to about half of the value obtained when rice is grown in a … This means that brown rice, (unmilled or unpolished rice that retains its bran) contains more arsenic than white rice.

I used a brown basmati rice. 90 fractions of both parboiled and nonparboiled rice. Brown rice has 80 percent more inorganic arsenic on average than white rice of the same type. Rice has higher levels of inorganic arsenic than other foods, in part because as rice plants grow, the plant and grain tend to absorb arsenic more readily than other food crops.
