Physical Properties of Egyptian Artichoke Heads “Kharshoof"

Abstract

Artichoke physical properties studies are very important as design parameters for each of handling, sorting and packing applications. Some physical characteristics and mechanical properties of the local artichoke cultivar (Balady) were investigated directly after harvesting at a moisture content of about 86.17% (wet basis). The physical characteristic include equatorial diameters, height, single bud volume, surface area and weight, spheresty, particle density, bulk density and porosity. The mechanical properties include the parameters of stress-strain radial compression test as bio-modulus of elasticity, bio-yield force, yield stress and strain, and biorupture stress and strain. The results showed that the artichoke buds which were under study had diameter range from 46.
