- 摘要:
- 为明确应用近红外品质分析仪测定马铃薯淀粉的可行性以及准确性,利用瑞士Perten公司DA7200型近红外品质分析仪对黑龙江省农业科学院克山分院马铃薯资源圃400份马铃薯淀粉进行分析定标,建立曲线,进而进行回测验证。结果表明,应用近红外品质分析仪测定马铃薯淀粉具有可行性,且采集马铃薯品种数越多,最终定标建立起来的数学模型曲线越能接近真实值,回测后数据和水比重法相关度越高。
- Abstract:
- To ascertain feasibility and accuracy of determinating potato starch by DA7200 near infrared quality analyzer produced by Switzerland Perten Company, 400 potato materials from potato repository of Keshan Branch of Heilongjiang Academy of Agricultural Sciences were analyzed and calibrated, starch curve was established and then carried out back-test verification. The results showed that it had feasibility to use the analyzer to determinate potato starch, and collected more varieties, mathematical model curve more approximated the true value, and correlation degree of back-test data was more higher compared with water-proportion method.
