大麦容重与杂质的相关性研究
目的 研究大麦杂质对容重的影响。方法 采用添加杂质的方法将美国、澳大利亚、加拿大大麦样品分别制成杂质含量为0%、5%、10%、15%、20% 的试样, 按照 GB/T 5498-2013(粮油检验 容重测定)的方法测定每份样品的容重, 并用DPS数据处理系统进行差异分析。结果 随着杂质含量的增加, 其样品容重均呈现降低趋势, 且在10%时容重降低量最大。除了澳大利亚大麦杂质含量在15.0%和20.0%时差异没有统计学意义, 其他不同杂质含量间差异均存在统计学意义(P<0.05)。美国、澳大利亚、加拿大大麦都随着杂质含量的增加呈线性相关, 其相关系数分别为0.998、0.974、0.985。结论 该方法快速、简便、准确, 对于检验检疫口岸检测具有一定的指导意义。
Objective To study the influence of foreign matter on the bulk density. Methods Different content (0%, 5%, 10%, 15%, and 20%) of foreign matter was added into American barley, Australian barley and Canadian barley. Then the bulk density was detected according to GB/T 5498-2013 (Inspection of grain and oilseeds, methods for determination of test weight). The data were analyzed by DPS. Results The bulk density of each barley sample showed a decreasing trend as the content of foreign matter increased, especially 10%. In addition to Australia barley 15% and 20%, other differences were statistically significant (P<0.05). American barley, Australian barley and Canadian barley were linearly related with increase of impurity content, the correlation coefficient were 0.998, 0.974, and 0.985, respectively. Conclusion The method is rapid, simple and accurate, and has certain guiding significance to the inspection and quarantine port detection.
