Detection of Ginger Powder Adulteration by ATR-FTIR Spectroscopy Using Class-Modelling and Discriminant Approaches

Key Points

• Detection of ginger powder adulteration shows a high accuracy rate with integrated class-modelling techniques.
• Using ATR-FTIR spectroscopy, 95% accuracy was achieved in distinguishing pure from adulterated ginger samples.
• Class-modelling and discriminant approaches were utilized to analyze spectral data effectively for adulterant identification.
• Reliable detection methods may enable improved food safety and authenticity checks in spice quality control.
