以153个单植物源和混合植物源蜂蜜样品为研究对象,使用3种近红外光谱仪(FT型、CCD型、PDA型)采集蜂蜜的透反射和透射光谱,并应用近红外定量分析技术进行蜂蜜中主要成分(水分含量、果糖含最、葡萄糖含量)的检测研究.用偏最小二乘回归(partial least square repression,PLSR)方法分别建立了蜂蜜水分含量、果糖含量、葡萄糖含量的近红外定量分析模型.结果表明,水分含量、果糖含量、葡萄糖含量的相关系数(r)分别达到0.978 5,0.931 1和0.890 7,预测误差均方根(RMSEP)分别为0.410 8(%),1.914 4(%)和2.531 9(%).研究表明基于近红外光谱的蜂蜜主要成分快速无损检测准确度高,具有很高的实用价值.

The potential of near infrared spectroscopy (NIR) as a nondestructive method for determining the principle compo-nents of honeys was studied for 153 unifloral honeys and multifloralh honey samples. Fourier transform near-infrared spectrosco-py (FT-NIR), CCD near-infrared spectroscopy and PDA near-infrared spectroscopy were evaluated to quantitatively determine water content, fructose content and glucose content in honey. On the basis of partial-least square (PLS) regression, the models of honey were compared. The best calibration model gives the correlation coefficients of 0. 978 5, 0. 931 1 and 0. 890 7 for water, fructose and glucose, respectively, with the root mean square error of prediction (RMSEP) of 0. 410 8(%), 1. 914 48(%) and 2. 531 9(%) respectively. The results demonstrated that near-infrared spectrometry is a valuable, rapid and nondestructive tool for the quantitative analysis of the principle components in honey.
