Compliance overview
Scope and applicability
This standard applies to commercial maize involved in purchasing, storage, transportation, processing, and sales. It is mandatory for all commodity maize entering the Chinese market. The standard explicitly excludes waxy maize, sweet maize, and other special varieties not covered in its classification. It categorizes maize into yellow maize, white maize, and mixed maize based on seed coat color.
Technical requirements
GB 1353-2018 specifies mandatory quality and food safety requirements for maize. The primary grading indicator is test weight, which determines the grade from 1 to 5, with an adjusted grade interval of 30g/L. Manufacturers must ensure their products meet the specified test weight to achieve the corresponding grade. The standard also sets limits for defective kernels (including insect-damaged, spotted, broken, and heat-damaged kernels), severely moldy kernels, foreign matter, and moisture content. Compared to the previous GB 1353-2009, this version has increased the test weight requirements and removed the limit for moldy kernels (though severely moldy kernels remain regulated). All maize must exhibit normal color and odour, free from abnormal smells. Additionally, food safety and animal/plant quarantine requirements must comply with relevant national standards and regulations.
Testing methods
The standard outlines specific testing procedures referencing various national standards. Key testing methods include: Sampling and sample splitting according to GB/T 5491; Color and odour inspection per GB/T 5492; Type and intermixing inspection following GB/T 5493; and Impurities, defective kernels, and severely moldy kernels inspection based on GB/T 5494. Moisture content is tested using GB 5009.3 (or LS/T 6103 for high moisture), and test weight is determined according to GB/T 5498 (or LS/T 6117 for high moisture).
