The preparation of a new electrochemical sensor for the detection of mature level in vanilla flavor

摘要

In this patent, we are interested in developing a new nanotechnology analysis method to detect fraud in vanilla products, which is applied to the food, cosmetics and pharmaceutical industries. Carbon electrodes have been modified with zirconium doped aluminum nanoparticles ("AlO2") films ("Zr" / "alo2np") to provide sensitive and selective electrochemical sensors for the quantification and measurement of adultery.S in vanilla Electrochemical sensor (Zr/ The phenolic compounds of vanilla flavor to be analyzed are: VanillaP-hydroxybenzoic acidP-hydroxybenzaldehydeVanillinVanillic acid and ethyl Vanilla The proposed method quantifies vanilla compounds in a linear range of 0.5 to 10 mg / L with detection limits, quantification limits, and relative type deviations of less than 0.14 mg / L.0.48 mg / L and 4.76%part The validity and reliability of the proposed method have been verified in a number of food samples.
