摘要

为了有效地定量检测植物调和油中的单一植物油

建立了便携式荧光植物调和油测试系统并对该系统所采用的测量调和油中单一植物油含量的算法进行研究。首先

设计了便携式荧光植物调和油的系统硬件

以市场上常见的葵花油

大豆油

花生油配置了植物调和油。测量了各种不同比例调和油的荧光光谱及各单一植物油的含量

依据偏最小二乘回归建立相应的数学模型

作为标准数据库。然后

将待测调和油光谱数据带入建立好的偏最小二乘回归模型进行计算

得出待测调和油中单一植物油的含量。实验结果表明:依据建立的偏最小二乘回归模型计算出的待测调和油中各植物油含量的准确率偏差在10%以内。该测试系统测量快、准确度好

需要试样量少

基本满足调和油中各种植物油含量的要求。

Abstract

To measure quantitatively each single vegetable oil in blend oil

a portable fluorescence blend oil measuring system was established and an algorithm for the measurement of each single vegetable oil in the blend oil was investigated. Firstly

the hardware was designed for portable fluorescence blend vegetable oil measuring system. Then

sunflower oil

soybean oil and peanut oil commonly sold in the market were mixed into blend vegetable oil. The fluorescence spectra of different proportions of blend oil were measured and the content of each single vegetable oil was tested. A corresponding mathematical model was established based on partial least-square regression model to be used as a standard database. Furthermore

spectral data of the blend oil under the test was taken into the partial least-squares regression model established before to calculate and to obtain the content of single vegetable oil in the blend oil. Experimental results indicate that deviation of test accuracy of calculated content of each vegetable oil in the blend oil is within 10% based on the partial least-squares regression model. The measuring system has higher measuring speed

good accuracy and needs a few samples

and it satisfies the system requirements of the quantitative measurement for each single vegetable oil in blend oils.
