Post Harvest Physical and Nutritional Properties of Two Apple Varieties

In this research, physical and nutritional properties of two Iranian apple varieties (Golab Kohanz, Shafi Abadi) were determined and compared. The physical properties were average fruit length, width and thickness, geometric, arithmetic and equivalent mean diameters, projected area, surface area, sphericity index, aspect ratio, fruit mass, volume, bulk and fruit densities and coefficient of static friction and the nutritional properties werePH, titratable acidity and total soluble solids. Average moisture content of the Golab Kohanz (GK) and ShafiAbadi (SA) varieties were 86% and 84% (w.b.), respectively. Based on statistical analysis, the properties werestatistically different at 1% and 5% levels of significance for both varieties. However, the differences betweenthe two studied varieties in the case of the aspect ratio, coefficient of static friction on various surfaces and PHwere not significant (P>0.05).
