Spectrometers detect toxic trace metals in rice products

Highly accurate trace metal detection in rice products is possible thanks to Thermo Fisher Scientific’s iCE 3000 Series range of atomic absorption (AA) spectrometers, claims the company.

This range of AA instruments allows quick and easy optimization for precise flame and furnace analyses of nutritional and toxic elements in rice products at parts per million and parts per billion levels, said a statement from Thermo Fisher Scientific.

Targeted toxic elements include copper, zinc and manganese which are natural constituents in soils and water.

Cadmium and lead

Also included in the research were cadmium and lead which are toxic elements with no nutritional benefit.

Rice is the world’s second-most common cereal crop making trace element analysis a vital safeguard for consumer health. “Trace elemental analysis of rice and related products is important on a nutritional and toxicological level, and the analysis of heavy metals is of particular importance to human health,” said the company.

International regulations regulate the permissible levels of cadmium in foodstuffs. For example, both China and the EU set an upper limit of 0.2 mg/kg of cadmium in rice. The company says its iCE 3000 Series is the ideal tool for accurate and rapid determination of multiple trace elements in rice and rice products.
