Mapping Elemental Nutrient and Surface Treatment Distribution in Produce
Poster Apr 03, 2017
Nutritionists address the benefits of obtaining elemental nutrients directly from food, especially fresh, uncontaminated produce. This project will demonstrate non-destructive techniques developed to visually map distribution and relative abundance of elemental nutrients and treatments of produce.
Three types of X-ray fluorescence (XRF) spectrometers were used. All provided user control of atmosphere, power, filters and collimators for optimization of elemental analysis in various matrices. They also provided qualitative and quantitative XRF elemental analysis software.
Data presented will include maps of elemental nutrient rich locations in fruit as well as distribution of elemental surface treatments for preservation of produce from farm to market. The various methods utilized for data collection will be described. Future research planned includes monitoring elementall nutrient distribution changes over time and with different storage conditions.
Concern about the safety of food products has increased dramatically with intentionally and non-intentionally added substances (NIAS) used in packaging being of particular interest. APGC and high resolution MS together with a workflow driven process was used to identify unknown compounds in packaging.READ MORE
In April 2017, a campus-community event (N=42 participants) was held to promote sustainable food systems by educating participants about concepts ranging from food production to nutrition and food waste management. This poster discusses the resulting increased awareness and knowledge of a our local food system among participants, which can be fostered through educational events that combine opportunities for research, teaching, and practice.READ MORE
