Research Project: Evaluation of Wheat Tortilla Quality Using Near-infrared Spectroscopy

Location: Grain Quality and Structure Research

Project Number: 3020-44000-027-002-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2023

The goal of this project is to assess the potential of near-infrared spectroscopy (NIRS) in the evaluation of tortilla quality. Specific objectives are: 1) Determine the potential of NIRS to detect molecular changes that occur in tortillas during the staling process and correlation to subjective analysis (rollability) and objective analysis. 2) To measure and analyze the objective and subjective textural properties of the product such as rollability, color, diameter, height, and stretchability, rupture force, distance to rupture force.

TAMU will provide flour samples from and produce tortillas from selected samples for analysis. Grain chemistry and compositional analysis from these samples will be analyzed by ARS.
