Abstract: 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 conditionsSummary: Elemental mapping of produce with XRF helps quickly identify nutrient rich locations; it also helps understand fortification distribution of processed foods. XRF even helps optimize surface treatments for preservation of produce from farm to market to help minimize financial loss caused by transport. Further studies planned include examination of the distribution of elemental nutrients over time and with different storage conditions.
