Some chemical and physico mechanical properties of pear cultivars

Demir, Bünyamin

Two pear (Pyrus communis L.) cultivars namely Deveci and Santa Maria, which dominate pear production in Turkey, were analyzed for several physico-mechanical (moisture, fruit dimensions, aspect ratio, geometric mean diameter, sphericity, surface area, projected area, fruit mass, fruit volume, fruit density, bulk density, density ratio, porosity, coefficient of static friction, rupture force, deformation, absorbed energy, fruit firmness, toughness, hardness and skin color values) and chemical (protein, fatty acids, ash, pH, acidity, vitamin C, total soluble solids, antioxidant activity, total phenolic content and mineral elements) properties. There is a statistical difference between cultivars in terms of most of the physico-mechanical and chemical properties. The average fruit mass ranged f...
