Honey adulteration is one of the most prominent issues in food production. Herein, the alternating current (AC) impedance spectroscopy combined with1H NMR profile were used to reveal the adulterants in acacia honey. Variation of electrical parameters such as solution resistance (Rs), double layer capacitance (CD), charge transfer resistance (RCT) and1H NMR profile for 10%-90% (w/w) syrups or rape honey adulterated acacia honey samples were analyzed. We clearly demonstrate that the difference of the AC impedance between acacia honey and adulterated honey is obvious, and the levels of RCT of acacia honey samples are always smaller than those of syrups and adulterated honey. Furthermore, the relaxation peaks shift toward the lower frequency zone and gradually increase in intensity with increasing proportion of syrup or rape honey. Also, 1H NMR profile can clearly indicate the adulterant and adulteration proportion, supporting the results...
