Presentation: Zaijing Sun

Dr. Sun was invited by the Center for Neutron Research at the National Institute of Standard and Technology and presented his research “A Preliminary Study of the Organic and Nonorganic Food Ingredients with Instrumental Neutron Activation Analysis” at the NCNR Seminar series.

In the talk, he claimed that there is not much difference in the trace elements content between organic food and its conventional counterpart. The experiments and data show that INAA, as a nuclear technique, lacks the capability to probe the properties of compounds on the molecular level, which may be the real difference between organic and non-organic food.
