Technology of identification of the production origin should benefit the effective management of local rice market. Analysis of multi-elements content profiling has gradually been shown as an effective method for the discrimination of production origin of crop products including rice. The objective of present project is to develop technique for differentiating geographic production origin of rice grains. In our previous study we have developed a procedure that can determine the multi-elements content profiles for local and foreign rice grains, by using ICP-AES instrument. In the current study more rice samples from local and foreign countries are to be collected. Data bank of multi-elements content profiles of these samples is to be built up. Statistic analysis through the data bank will be performed to explore the possibility of differentiate production origin of rice samples. An integrated protocol including multi-elements profiling and other characteristics is further expected to be approached to develop a practical and effective technique for the identification of geographic origin of rice grains in Taiwan market.稻米礦物元素含量產地判別ricemineral contentproduction origin
