Abstract

In this study, the physical, mechanical and chemical properties of medlar during physiological maturity and ripening period were determined. The physical properties such as geometric mean diameter, sphericity, bulk and true densities, porosity, projected area and colour characteristics were measured during physiological maturity and ripening period of medlar. Mechanical properties such as rupture force, deformation and rupture energy and chemical properties (total soluble solid content, titratable acidity and pH) of medlar fruit were determined. The geometric mean diameter, sphericity, surface area and fruit density of medlar decreased, while, bulk density increased at ripening period. The fruit density of medlars increases of 10.9% occurred while bulk density and surface area decrease of 19.7% and 23.81% observed from physiological maturity to ripening period of medlar fruit, respectively. The static coefficients of friction of medlar fruit during physiological maturity and ripening period were higher for rubber than the other surfaces. The total soluble solid content and total acidity of medlar fruit decreased at ripening period.

Abstract

Bu çalışmada, muşmula meyvesinin hasat ve yeme olumu dönemindeki fiziksel, mekanik ve kimyasal özellikleri belirlenmiştir. Fiziksel özellikler olarak geometrik ortalama çap, küresellik, yığın ve gerçek hacim ağırlığı, porozite, projeksiyon alanı ve renk özellikleri hasat ve yeme olumu döneminde ölçülmüştür. Mekanik özellikler olarak kopma kuvveti, deformasyon ve kopma enerjisi belirlenmiştir. Muşmula meyvesinin kimyasal özellikleri olarak toplam suda çözünebilir kuru madde, titre edilebilir asitlik ve pH değerleri belirlenmiştir. Geometrik ortalama çap, küresellik ve meyve hacim ağırlığı yeme olumunda azalırken, yığın hacim ağırlığı ise artış göstermiştir. Muşmulanın meyve hacim ağırlığı hasat olumundan yeme olumuna kadar %10,9 oranında azalırken, yığın hacim ağırlığı ve yüzey alanı ise sırasıyla %19,7 ile % 23,81 oranında azalmıştır. Muşmula meyvesinin hasat ve yeme olumunda statik sürtünme katsayısı değerleri lastik yüzeyde diğer yüzeylere göre daha yüksek bulunmuştur. Muşmula meyvesinin toplam suda çözünebilir kuru madde ve toplam asitlik değeri yeme olumunda ise azalma göstermiştir.
