This technical document discusses the automatic pretreatment of rice (brown rice and white rice) and rice ears using the nitric acid reflux method with the automatic pretreatment device "DEENA," which employs automatic pretreatment such as reagent addition and acid decomposition.
Regarding cadmium contained in rice, the standard has been set at 1 ppm (mg/kg) until now, but in April 2010, a revision was issued to part of the standards for food and additives, changing the standard for cadmium and its compounds contained in rice (brown rice and white rice) to below 0.4 ppm (mg/kg).
In conventional methods, wet decomposition typically involves the use of nitric acid, sulfuric acid, or perchloric acid, which are time-consuming and labor-intensive, making it difficult to process multiple samples quickly.
Therefore, we examined the automatic pretreatment of rice (brown rice and white rice) and rice ears using the nitric acid reflux method with "DEENA," which can perform tasks such as acid addition, stirring, and dilution under PC control in a fully automated manner.
