Estimating Apple firmness using Tensile Mechanical Properties
Author: Dr. Marvin J Pitts, Dr. Carolyn Ross
Published: 2007
Summary: The objectives of this project were: 2005 1. Determine if human perceived apple firmness is related to the tensile material properties (elastic modulus, failure stress) of tissues from cultivars of apples and pears commercially grown in Washington State. 2. Determine if there is a relationship between the tensile material properties of the apple and pear varieties and the firmness pressure test originally developed by Magness and Taylor and refined over the years. 2006 1. Confirm 2005 results. 2. Develop design tools for use in designing and evaluating destructive and nondestructive firmness sensors.
