Abstract
In order to study the Raman spectrum of sodium dehydroacetate and the vibrational mode between its molecular chemical bonds,the density functional theory was used to calculate and analyze the Raman spectrum peaks.The preparation conditions of silver sol were optimized by different dosages of sodium citrate and different heating durations.Additionally,the surface-enhanced Raman shift of sodium dehydroacetate in flour was qualitatively studied.Detection results showed that the solid standard of sodium dehydroacetate had obvious Raman characteristic peaks at 358,631,1 260,1 404,1 660,2 928 cm-1.By optimizing the preparation conditions of silver sol,the minimum detection limit of sodium dehydroacetate in flour was 0.1%.The enhanced Raman spectra of sodium dehydroacetate spiked in flour were pretreated and combined with stoichiometry to establish the best partial least squares model which realized the rapid detection of sodium dehydroacetate in flour.关键词
