山茶油掺假大豆油中红外检测仪的研制
|
摘要
为了实现对山茶油掺假的快速无损检测,基于中红外LED光源和MSP430F149研制了一种便携式山茶油掺假检测仪。为了验证仪器的精准度,将滤光片组合下采集到的样品吸光度作为原始参数,利用Matlab仿真平台、采用多元线性回归算法和偏最小二乘法,建立了山茶油掺假大豆油浓度的红外光谱定量模型。经对山茶油掺入大豆油的检测表明,该检测仪实际应用效果良好,能够满足现场品质分析的需求。
In order to achieve rapidly and non-destructively detect the camellia adulteration, a portable detector for camellia oil adulteration based on mid-infrared light source and MSP430 F149 was developed. In order to verify the accuracy of the instrument, the absorbance of the sample collected under the filter combination was taken as the original parameter. The quantitative model of the concentration of camellia oil adulterated soybean oil was established by Matlab simulation platform, multivariate linear regression and partial least squares model. The detection of camellia oil adulteration with soybean oil shows that the detector is effective in the real applications and can meet the requirements of on-site quality analysis.
