| titleOfInvention | A kind of method utilizing Raman enhanced spectrum to detect synthetic dyestuff in food |
| abstract | The present invention relates to a kind of method utilizing Raman spectroscopy to detect synthetic dyestuff in food, belong to field of detection of food safety.It is characterized in that: utilize mercaptoethylmaine modified nano gold to synthesize a kind of positively charged nano gold sol, utilize this colloidal sol as Raman spectrum Contrast agent, detect the synthetic dyestuff in food.In testing process, Contrast agent and testing sample mix, Laser Focusing, and Raman spectrum detects.Sunset yellow, acid orange, lure red, lemon yellow, light blue, red scarlet, famille rose, the synthetic dyestuff molecular band negative charges such as quinoline yellow, and structure is similar, positively charged Raman spectrum Contrast agent can make synthetic dyestuff molecular adsorption on nm of gold surface by electrostatic interaction, utilizes Raman enhanced spectrum technology to obtain rapid sensitive and detects.So, utilize the method can the synthetic dyestuff molecule of detection zone negative charge.Synthetic dyestuff in food of the present invention, operating process is fast economical, and result is accurate. |
