Rapid and Accurate Discrimination Between Pure and Adulterated Commercial Indian Honey Brands Using FTIR Spectroscopy and Principal Component Analysis

Four leading commercial Indian honey brands were investigated using FTIR spectroscopy and principal component analysis for a rapid and accurate differentiation of pure, mildly adulterated, and highly adulterated honey brand samples. This study is first of its kind investigating commercial Indian honey brands using FTIR and PCA, hence can be used for investigating adulterations in bulk commercial honey brand samples where sophisticated instrumentations and facilities are not available.
