Discovery Park Undergraduate Research Internship Program

"Response of x-rays for food density determination"

About the Project

Project Time & Type:
Summer 2012 - DURI
Research area(s):
Food Engineering
Project Description:
Density is an essential physical characteristic used to assess the quality of foods. For dietary assessment methods, density is required for food calories measurement. For porous foods, accurate measurement of density is challenging. Preliminary experiments demonstrated the capability of x-ray imaging as a non-destructive tool to determine food density. A model to measure density based on x-ray attenuation is currently under progress. The goal is to use x-ray computed tomography for complete density measurement of food systems.
Expected Student Contributions:
The intern will assist in data collection and analysis of food systems. The intern will become familiar with x-ray computed tomography and learn to use imaging tools for volumetric measurement. The intern will be expected to apply image processing techniques for characterizing food structure.
