“…In general terms, Equation ( 5) represents the contributions in diameters through a growth ratio. Tinoco and Peña [8] showed that the relation is constant, independent of the ripening stage of the coffee fruit. In a practical application, Equation ( 5) is used to predict the geometric dimensions using 1 φ as an input parameter, which permits the parametrization of the geometry of the orange.…”

“…However, the first impression could be misleading when mathematics represent complex geometries, as demonstrated by different studies [23,25,26]. To show and convey these ideas, Tinoco and Peña [8] established a relation between orthogonal diameters of coffee fruits (Coffea arabica L. var. Colombia), which demonstrated that rounded fruits grow systematically keeping its shape constant, through its diameters.…”

“…These changes can imply affectations in the quality requirements, as a commercial product. Other characteristics like the fruit shape are considered to be a crucial feature of the postharvest process, since several conditions depend on this parameter; i.e., cooling [3], convective drying [4], short-and long-term storage [5], and selective harvesting by mechanical vibrations [6][7][8].…”

“…However, to overcome this limitation, mathematical approximations based on spheres, ellipses, cylinders, and combinations are used as the basis for the geometrical description of fruits [12,[16][17][18][19]. In some cases, these models can be applied; nevertheless, these are not very useful to characterize mechanical properties, due to the physical dependencies with the geometry [8,12,13].…”

The computer-aided design of fruits are used for different purposes, e.g., to determine mechanical properties by applying engineering simulations, to design postharvest equipment, and to study the natural changes related to the topology. This paper developed a methodology to model Valencia orange (Citrus sinensis), applying Bézier curves and an image-based CAD approach; the orange geometry was designed for different ripening stages. In the modeling process, a 3D construction was carried out using third-order Bézier curves, adjusted to the images taken in orthogonal planes. Four control points defined each profile to compose the geometric pattern of the orange, with geometric errors lower than 3%. Two prediction models were proposed to relate the orthogonal dimensions with a factor size; this means that two dimensions out of three can be predicted. The results showed that the shape ratios kept constant in any ripening stage; however, the radius of curvature evidenced differences in the analyzed shape profiles. The methodological framework presented in the paper might be used to draw other types of citrus fruits. This contribution is a tool to model fruits in 3D, instead of using expensive technological equipment, since it is only necessary to apply computer design tools.

Background: A deep understanding of the motion and the intensities of forces endured by the fruits overtime during the various handling processes is necessary if improvements are to be made in the handling systems or related tools. The finite element method (FEM) has been used to investigate the effect of mechanical loading on fruit before developing a prototype of the intended design. Simulation tests were performed to visualise the time-dependent deformation behaviour. Various studies have been reported on the use of FE for studying the effect of compression and drop forces on fruits. However, to the best of the knowledge of the authors, the application of finite-element analysis in fruit mechanics has not been summarized yet. Scope and approach: This review is concerned with establishing the introductory concept of FEM for evaluating fruit response under the static and dynamic loading. The FE equations were formulated based on the stress-strain constitutive equations. Key findings and conclusions: The review summarises the application of FEM for fruit stress-strain analysis. A brief description of the fundamentals and the existing models that have been developed to cope with problems of fruit mechanics are reported. This paper provides a review of the main FEM studies and a comparison between different types of stress analysis as well as outlining the potential use of FEM for future reference. This review can become an appropriate, timely and beneficial reference for any relevant follow-up research for the assessment of the quality of agricultural produces.
