Application of Near-infrared Spectroscopy in Food Adulteration Detection:A review

In recent years,food adulteration has been a serious problem in China.Currently the common detection methods for food adulteration are both time and effort consuming,and need large amount of chemicals.Near-infrared spectroscopy achieves the rapid,nondestructive,and on-line detection for food adulteration.This paper summarizes the application of near-infrared spectroscopy in adulteration detection for liquid foods such as edible oil,milk,honey,and beverages,as well as solid foods including meats,powdered milk,tea,and wheat flour.Meanwhile,limitations of near-infrared spectroscopy in adulteration detection are analyzed.Finally,this article outlines further study directions and proposed some suggestions.
