Detection and Quantification of Adulteration in Honey through Near Infrared Spectroscopy

Abstract

Honey is one of the important traditional medicines since ancient times. In this article, a case study was carried out using near infrared spectroscopy techniques with Chemometrics to detect the Jaggery adulterants in the honey. Jaggery was used to prepare adulterant solution of different proportionate by manually mixing with four types of different honey samples. In total, 160 spectra were collected using the XDSTM Optiprobe analyzer reflection type spectrometer and a calibration model was built using partial least square regression. The honey adulteration was predicted statistically with the calibration error 0.00751 and coefficient of determination R2 of 0.9924.
