新型国产近红外分析仪的菜籽菜粕快速检测技术研究

The research of rapid analysis for rapeseed and rapeseed meal based on a new type domestic near infrared analyzer

近红外光谱分析作为1种快速无损的绿色分析技术,可应用于检测油料原料和油脂产品品质,为粮油企业带来巨大经济效益。本文采用一款新型国产化的近红外漫反射光谱分析仪对菜籽和菜粕进行了检测分析,分别对菜籽的水分、蛋白、含油量、脂肪酸、硫苷含量和菜粕水分、蛋白和含油量指标建立模型并验证,结果显示近红外检测结果与国标参考方法检测结果相关性好、准确度高,表明新型国产化的近红外分析仪可满足油脂企业对菜籽和菜粕产品的质量控制要求。

Near infrared technology is one of nondestructive,rapid and green analysis technologies,and can be applied to the determination of oil and grease product as well as oil seeds quality by oil factories.The technology has brought huge economical benefits with factories.A novel domestic broadband（1000～1800） nm analyzer based on near infrared reflectance spectroscopy performs well and possesses the outstanding software integrated with the functions of spectra acquisition,modeling,remote control and management.The analyzer was successfully used to determinate contents of the moisture,protein,fat and amino acids in the rapeseed and rapeseed meal.The results show that predicated values for near infrared method are correspondingly near to reference values for national standard methods and the near infrared domestic analyzer can meet the requirement of quality controls for oil and fat products as well as oil seeds.
