The Research Of Detection Method About Characteristic Of Abalone Producing Area

This topic studied the origin protection by the abalone from different regions. We analyse the composition of the major samples and content. From the two aspects, we found the salient features.This paper consists of five chapters.The first chapter is summarize.In the first chapter, the concept of origin protection,the development at home and abroad,the significance,the relevant literature about origin characteristics,the necessity of the research about characteristic of abalone and the study in this paper.In the second chapter, the content of Potassium, Calcium, Sodium, Magnesium, Copper, Zinc, Iron, Manganese and Phosphonium abalone produced in different region were determined and analysed with flame atomic absorption spectrometry (FAAS). It is found that there is significant difference in some elements of abalone came from different regions,but the difference of some other elements is not significant. It can provide science foundation to evaluate the production area and to identify the characteristic.In the third chapter, Fourier transform infrared spectrum is used to determine the samples from different regions, characteristic peaks in IR fingerprint spectrum are identified and comparative analysis. Result: There are some differences between absorption frequency and relative intensity.Stable isotope analysis is an excellent tool for origin assessment and is important to food traceability. In the fourth chapter, isotope analysis applies to ecosystem research. we make use of stable isotope ratio mass spectrometry to determine and analyse the carbon and nitrogen isotope ratio of abalone in Dalian. The average of isotope ratio is 16.74‰and 7.60respectively.In the fifth chapter, To develop a method of discriminating the fingerprint of abalone by HPLC.We studied different sample pretreatment mobile phase,detection wavelength, temperature and compared the fingerprint chromatograms of abalone from three different areas . In order to further determine the origin of abalone to provide reference data,we determined the fingerprint differences.
