Based on the comparative analysis of the quality indexes and some important food safety indexes among the maize standards of some economies in the Asia Pacific region and the international Codex Alimentarius Commission, the report concluded that the tendency quality requirements of maize standards in various economies were the same, and the used quality indicators were similar. The maize quality standards of the economies tended to grade maize by the indexes of test weight, unsound grain, foreign mater, moisture, color, odor, and etc, to classify maize by the color of maize seed. There were differences in terms of definitions, testing instruments, testing methods, sensory testing and quality requirements. And the quality grade and result determination of the same sample tested and judged using the standard of different economies were divergent . Important safety indexes such as mycotoxins and exotic seeds varied greatly, especially the internationally recognized exotic harmful seeds. The suggestions were that we should start the research on the determination methods of test weight, unsound grain, foreign mater, moisture and other important indicators of maize in the Asia-Pacific region, unify the relevant determination methods and equipment, make a visual reference system for sensory detection indicators; and carry out discussions and exchanges among multi-layer testing technicians, collect testing data of maize samples, and further analyze the actual differences of maize standards in different economies; increase international peer communication and promote the coordination on maize quality standards, in order to form a unified or similar technical standard system conducive to realizing regional trade facilitation and integration.
