MiniRaman Spectroscopy for Analyzing Pumpkin Skin

Discover the unique chemical composition of pumpkin skin with Lightnovo’s miniRaman spectrometer. This study showcases how Raman spectroscopy reveals the presence of carotenoids responsible for the vibrant orange color of pumpkins.

Key Highlights:

  • Instrumentation: Measurements were conducted using the Lightnovo miniRaman Power 785 nm spectrometer with a middle-distance probe (15 mm) and settings of 91 mW power.
  • Advanced Corrections: Baseline corrections were applied to eliminate fluorescence background, revealing clear Raman signals.
  • Chemical Insights: Raman spectra identified carotenoids such as beta-carotene, lutein, and zeaxanthin, compounds that contribute to the characteristic orange color of pumpkin skin.


Lightnovo’s miniRaman 785 nm spectrometer is a reliable tool for analyzing natural compounds in organic materials like pumpkin skin. This compact device offers precise spectral analysis, making it ideal for both research and educational purposes.
