Application of UV-Visible Spectrophotometric Colour Analysis in Different Natural Product Identification
When light falls on a substance, a part of the light that interacts with a substance is absorbed, and the remaining light is either reflected or transmitted through the substance.

| Sumario: | When light falls on a substance, a part of the light that interacts with a substance is absorbed, and the remaining light is either reflected or transmitted through the substance. Colorimetric is used for the detection of dyes, food colourant in which the wavelength of light that different coloured dyes absorb varies. The majority of dyes are conjugated substances with alternate double and single bonds, and they generally absorb light in the visible spectrum. It is used for the food colourant studies due to the long history and widespread use of dyes in retail goods, the spectroscopic identification of food colourings appears to be a viable methodology. |
