Research Project:
Development of Field Deployable Optical Spectrometers with Chemometric Methods for the Analysis of Fiber, Food, and Grain Applications
Location:
Quality Assessment Research Unit
Project Number: 6612-44000-025-03
Project Type:
Specific C/A
Start Date: Aug 01, 2004
End Date: Jul 31, 2009
Objective:
Develop spectrometric devices with chemometric models to permit rapid field quality assessment of fibers, foods, and grains.
Approach:
Small field deployable optical (ultraviolet through mid-infrared region) spectrometers will be explored as rapid noninvasive means to assess quality and characteristics of fibers (e.g. cotton and flax), foods (e.g. cereals), and grains (e.g. rice, wheat, and barley). Field instrument performance will be compared/matched to laboratory instrument performance for methods already developed or under development by the Quality Assessment Research Unit. Calibration of instruments will be to accepted reference methods (ASTM, AOAC, and AACC). Chemometric multivariate analysis using MATLAB (The Mathworks, Inc.) and PLS_Toolbox (Eigenvector Research, Inc.) software will be used to generate models from reference and spectroscopic data.
