| Abstract: | Rapid qualitative and quantitative detection for melamine in pure milk was studied by using near infrared spectra(NIRS).Experiment was conducted by preparing two groups pure milk samples in which melamine content was different for qualitative and quantitative analysis.By combining NIRS technology with the cluster analysis method,two kinds of milk samples with and without melamine were classfied effectively.Spectrum pretreatment and wavelength choice methods were employed before model optimization.In this wa... |
| Keywords: | near infrared spectra(NIRS) melamine qualitative analysis quantitative analysis |
