Abstract

In this research, the physico-chemical properties and mineral composition of white Morus alba L. , black M. nigra L. and urmu M. nigra L. mulberries, grown in Southeast Anatolia region of Turkey, were investigated. Urmu contained the highest total anthocyanin and phenolic compounds 1071 mg cyanidin-3-glucoside equiva- lents, and 1456 mg gallic acid equivalents/100 g fresh matter respectively , and white mulbery had the highest HMF and browning index 36.15 mg kg-1 and 17.61 respectively . Maximum L and b values were observed in white mulberry. The mean values of mineral compositions of the mulberry types in 100 g fresh fruith were 238 mg P, 1138 mg K, 139 mg Ca, 116 mg Mg, 6 mg Fe, 0.8 mg Cu, 4.3 mg Mn and 3.9 mg Zn. The highest total flavonoid and ascorbic acid were determined in urmu mulberry 312 mg quercetin equivalents/100 g fresh matter and 32 mg/100 g .

Abstract

B u çalışmada, Türkiye’nin Güneydoğu Anadolu bölgesinde yetiştirilen beyaz Morus alba L. , siyah M. nigra L. ve urmulu M. nigra L. dutların fiziko-kimyasal özellikleri ve mineral bileşimi araştırılmıştır. Urmulu dutlar en yüksek toplam antosiyanin ve fenolik bileşikler içerirken 1071 mg siyanidin-3-glikozit eşdeğerleri, ve 1456 mg gallik asit /100 g taze madde sırasıyla eşdeğer ve beyaz dut en yüksek HMF ve esmerleşme indeksine 36.15 mg kg-1 ve 17.61 sırasıyla sahiptir. Maksimum L ve b değerleri beyaz dutlarda gözlenmiştir. 100 gram taze dut meyvesi çeşitlerinin mineral bileşimlerinin ortalama değerleri 238 mg P, 1138 mg K, 139 mg Ca, Mg 116 mg, 6 mg Fe, 0.8 mg Cu, 4.3 mg Mn ve 3.9 mg Zn. En yüksek toplam flavonoid ve askorbik asit 312 mg kuarsetin/100 gtaze madde ve 32 mg eşdeğer/100 g urmulu dutta belirlenmiştir
