| Physical characteristics of fruits and vegetables and their relationships are necessary for the design of some postharvest processing systems such as handling, sorting and packaging machines and reducing the processing costs. For proper design of grading systems, important relationships between the mass and other properties of fruits such as length, width, thickness, volumes and projected areas must be known. The aim of this research was to measure and present some physical properties of walnut fruits. In addition, walnut fruit mass was correlated to measured physical properties using linear, the Quadratic, S-curve and power models as three different classifications: (1) single variable regressions of walnut dimensional characteristics; (2) single variable... |
