Analysis of material identification method and application of leather
This article compares and analyzes material identification method,such as sensory identifica-tion,burning behavior,microscopy,infrared spectroscopy,PCR,to evaluate the accuracy of each method.Af-ter comparison,each method has its own advantages and disadvantages,sensory identification requires inspec-tors to have high professional skills and extensive practical experience;Burning behavior can only distinguish be-tween proteins and non proteins;Microscopy is susceptible to the influence of post-processing technology;Infrared spectroscopy is difficult to accurately identify natural protein fibers;PCR is difficult to operate,expensive and has certain requirements for instruments.
