Some physical, pomological and nutritional properties of kiwifruit cv. Hayward

Abstract

In this research, several physical, pomological and nutritional properties that are important for the design of equipments for harvesting, processing, transportation, sorting, separation and packaging of kiwifruit cv. Hayward grown in the Black Sea region of Turkey were determined. The fruit characteristics ranged from 72.28g for average fruit weight, 59.41, 46.28 and 42.87mm for fruit length, width and thickness, 49.03mm for the geometric mean diameter, 0.825% for sphericity and 66.52cm³ for the volume of fruit, respectively. The bulk density, fruit density and porosity were determined as 575.27kg/m³, 1,093kg/m³ and 47.13%. The highest coefficient of static friction was obtained on plywood as 0.190, followed by polyethylene, rubber and galvanized steel sheet as 0.173, 0.163 and 0.158, respectively. The total soluble solid content, acidity, vitamin C, ash and total nitrogen content of kiwifruit cv. Hayward were 7.32%, 1.64%, 108mg/100g, 0.71g/100g and 0.84%, respectively. The fresh fruits have 1.09mg/100g total chlorophylls and flesh color data represented as L, a and b were 57.18, 17.25 and 37.46, respectively.
