Development of a new electrochemical sensor for the measurement of adultery in vanilla fragrance

摘要

In this patent, we are interested in developing a new analytical method based on nanotechnology to detect fraud in vanilla products. This method is suitable for the food, cosmetics and pharmaceutical industries. In fact, zirconium-doped aluminium nanoparticles (ALO 2) film (ZR) (ZR/ALO 2NP) was used to modify the carbon electrode to provide a sensitive and selective electrochemical sensor for quantifying and measuring phenamine. WeS in Vanilla Flavor Electrochemical sensors (ZR/ALO 2NP) have been synthesized. The analytical methods used are hydraulic high pressure chromatography and hydraulic measuring sensors. The phenolic compounds of vanilla flavor to be analyzed are vanilla (VAN).P-hydroxybenzoic acid (P-HBA),P-hydroxybenzaldehyde (P-HB),Vanillin alcohol (V-OH),Vanillic acid (Av) and ethyl vanilla (V-Ethy). The proposed method quantifies vanilla compounds in a linear range of 0.5 to 10 mg/l, and the detection limit, quantification limit and relative type deviation are less than 0.14 mg/l.0.48 mg/l and 4.76%Namely The validity and reliability of the proposed method have been verified in several food samples.
