In the present study, a near-infrared (NIR) filter-based technique along with chemometrics as an analytical tool was used for determination of adulteration of Indian honey with jaggery. A total of 56 honey samples adulterated with different concentrations of jaggery syrup were analyzed using the NIR transflectance method at different wavelengths for multivariate analysis to develop a calibration model for jaggery adulteration in honey samples. The data were compressed using principal component analysis method and the model was developed using partial least square regression. The adulteration of all of the samples can be predicted with a standard error of calibration of 4.55 and a coefficient of determination (R(2)) of 0.81. The results demonstrate that the NIR technique along with chemometrics can be successfully used to determine jaggery adulteration in honey non-destructively.
在本研究中，使用基于近红外（NIR）滤波器的技术结合化学计量学作为分析工具，用于检测印度蜂蜜中糖蜜的掺假情况。使用 NIR 反射率法在不同波长下分析了 56 个掺有不同浓度糖蜜糖浆的蜂蜜样品，进行多元分析以建立用于蜂蜜样品中糖蜜掺假的校准模型。使用主成分分析方法对数据进行压缩，并使用偏最小二乘回归建立模型。可以使用校准标准误差为 4.55 和确定系数 (R(2)) 为 0.81 预测所有样品的掺假情况。结果表明，NIR 技术结合化学计量学可成功用于无损检测蜂蜜中的糖蜜掺假情况。
