Objective

To establish a method for identifying adulteration of Puerariae lobatae starch by analysis of microscopic morphological characteristics.

Methods

The microscopic morphology of self-prepared authentic Puerariae lobatae starch, corn starch, cassava starch, sweet potato starch and potato starch were observed by using scanning electron microscopy. Through characteristic analysis, the main typical morphologies of various starch microparticles were summarized and described. Then microscopic morphology analyses were conducted respectively on the simulated Puerariae lobatae starch adulterated with corn starch, cassava starch, sweet potato starch and potato starch, summarized the morphological differences and identification points to verify the reliability of the method and carry out the analysis of actual samples.

Results

The differences of microscopic morphological characteristics could distinguish Puerariae lobatae starch from corn starch, cassava starch, sweet potato starch and potato starch when the adulteration was present.

Conclusion

The analysis method of microscopic morphological characteristics can be used to identify the adulteration of Puerariae lobatae starch. The method is simple and does not require sample pretreatment, it can be provide an intuitive and convenient technical for the Puerariae lobatae starch adulteration identification.
