Lycopene wavelength
WebIn contrast, this result of the lycopene prediction model was lower than what had obtained in predicting the lycopene content of watermelon puree with a predicted value R 2 of 0.97 and a SEP of 3.4 mgkg −1 within a visible wavelength of 500–750 nm. WebWhile interaction with infrared light causes molecules to undergo vibrational transitions, the shorter wavelength, higher energy radiation in the UV (200-400 nm) and visible (400-700 nm) range of the electromagnetic spectrum causes many organic molecules to undergo electronic transitions.What this means is that when the energy from UV or visible light is …
