Abstract

The invention discloses a method for simultaneously measuring hybrid pigment by synchronous fluorescence spectroscopy with an RBF (Radial Basis Function) neural network. The method disclosed by the invention comprises the steps of preparing for a sample, measuring by the synchronous fluorescence spectroscopy, denoising synchronous signals, establishing a nonlinear model of the RBF neural network, etc. Three-dimensional fluorescence spectrum is replaced by the synchronous fluorescence spectroscopy; with the help of the RBF neural network, spectrum can be narrowed; spectral overlap is reduced; and furthermore, synchronous measurement of hybrid pigment without any chemical separation can be realized by utilizing the nonlinear advantages of the neural network.

Description

technical field

[0001] The invention provides a method for simultaneous determination of mixed pigments by synchronous fluorescence spectrum combined with RBF neural network, which belongs to the field of rapid quantitative detection of synthetic pigments. Background technique

[0002] Synthetic food coloring is the most commonly used food additive, and the research on its toxicity, safety and detection technology has been paid more and more attention by scholars at home and abroad. Common detection methods for synthetic food pigments include high performance liquid chromatography, thin layer chromatography, capillary electrophoresis, liquid chromatography-mass spectrometry, spectrophotometry, polarography, and voltammetry. However, these existing detection methods each have a certain scope of application, and are mainly applicable to the detection of a single or limited number of targets. Moreover, these methods require more complex pre-processing of the sample to be teste...
