| 摘 要： | 利用傅里叶近红外光谱分析技术,以磷虾粉样品的实测值与模型预测值为基础,研究了采用最小二乘法建立磷虾粉原始样品与磷虾粉混合样品中水分、脂肪和蛋白含量近红外定标模型的可行性和准确性。结果表明,磷虾粉近红外图谱最佳预处理方式为:标准正态变换预处理+一阶导数+Norris导数滤波;以磷虾粉混合样品构建的近红外模型较磷虾粉原始样品构建的模型在交互验证均方根误差、外部验证残差均方根（root mean square error of external prediction, RMSEP）(root mean square error of external prediction, RMSEP)和外部验证用样品真实值的标准差与RMSEP的比值(the ratio of the RMSEP to standard deviation of reference data in the prediction, RPDEV)等参数有所提升;经预处理后,定标模型的建模相关系数、交互验证相关系数和外部验证相关系数(correlation coefficient in external va...

| Abstract: | The Fourier transform near infrared spectroscopy(FT-NIR)analysis technology was used to establish the calibration model based on partial least squares(PLS)for the measurement and predication of Antarctic krill meal samples.The feasibility and accuracy of calibration model for predicting moisture,fat and protein content in atarctic krill meal samples was explored in this study.The result showed that the optimal pretreatment method for the NIR spectra was standard normal variate transform(SNV)+first derivative(FD)+Norris derivative filter(NDF).Compared with the original samples,root mean square error of cross validation(RMSECV),root mean square error of external prediction(RMSEP)and the ratio of the RMSEP to standard deviation of reference data in the prediction(RPDEV)of the calibration model of mixed samples were improved.After pretreatment,the correlation coefficient in calibration(REV),the correlation coefficient in cross validation(REV)and correlation coefficient in external validation(REV)of the calibration model was above 0.94.However,the REVof the fat was 0.9058 and RPD was above 2.5.Therefore,NIR technology can be used to quickly,conveniently and accurately determine the moisture,fat and protein content of shrimp meal.This study provided reference data for the onboard application of near infrared spectroscopy(NIR)technology for rapid determination of the quality of antarctic krill meal. |
