摘　　要：针对我国爆裂玉米产业的技术需求和品质检测中存在的问题,对爆裂玉米品质检测内容和测定方法做系统研究。结果表明,玉米粒体积测定,采用规格越小的量筒测定值误差越大,当量筒规格达到1 000 mL以上时测定值趋于稳定;玉米花体积检测,量筒规格越小,误差越大,当锥形量筒规格达到500 mL以上时测定值趋于稳定,直形量筒规格直至达到2 000 mL时仍存在较大差异;容重的测量,玉米相关标准《GB 1353-2018》规定用容重器测定容重,用直形量筒测定爆裂玉米容重与容重器测定结果没有较大差异;用量筒测定,既能保证测定结果的准确性又能对容重器不能测定的小量样品进行测定。引进容重指标后,可通过膨爆倍数与国际通用指标CC/g之间的关系,实现国内外不同技术指标之间的比较。A system research on the test content and methods of popcorn quality, for which the problems of technical requirements and quality inspection of the popcorn industry in China. The result shows that the greater error in the measured value, when the specification reaches 1 000 mL or more, the measured value tends to be stable;Corn flake volume testing, the smaller the size, the greater the error. The measured value tends to be stable when the specifications of the conical measuring cylinder reach 500 mL or more, while there are still large differences until the specifications of the straight measuring cylinder reach 2 000 mL. For the measuring of unit weight, the relevant standard of corn“GB 1353-2018”stipulates that measuring unit weight with grain unit weight device. This test shows that the results of straight measuring cylinder and grain unit weight device for measuring the unit weight of popcorn has little difference. Using a straight measuring cylinder to measure the unit weight of popcorn can not only ensure its accuracy, but also measurement of a small amount of samples that cannot be measured by the grain unit weight device. After the introduction of unit weight indicators, the comparison between different index units at home and abroad can be achieved through the relationship between the expansion ratio and CC/g.
