Outline of Final Research Achievements

For the products derived from different origins as organic synthesis and naturally extraction with an identical chemical structure, it is disable to distinguish their origin depending on the traditional test, such as morphological appearance and analytical standard applied to the food additive. In this research work, stable isotopic composition of curcumin derived from extraction of natural turmeric and organic synthesis of chemicals were analyzed to evaluate the possibility of original identification. As the results, nitrogen and oxygen isotope was presented difference to the turmeric from domestic or foreign origin. In addition, hydrogen stable isotope is considered as an effective approach to the manufacture traceability for curcumin with different origin.
