ÖZ
Bu çalışmada, farklı lokasyonlardan toplanan tamamen olgunlaşmış kestane (Castanea sativa Mill.) meyveleri’nin kimyasal özellikleri (nem, kül, ham yağ, ham lif, toplam karbonhidrat, toplam fenol ve mineral madde içeriği) belirlenmiştir. Kestane meyveleri’nin toplam fenol içeriği 21.8-‐24.7 g GAE/100 g arasında değişmiştir. Kestane meyvesi’nin bazı makro ve micro element içerikleri ICP-‐AES ile tespit edilmiştir. Kestaneler farklı miktarlarda Ca, Mg, K, P, Na ve Zn içermektedir. Bu değerler, sırasıyla 2090-‐2710 ppm, 1216-‐1713 ppm, 10719-‐14867 ppm, 1627-‐1849 ppm, 297-‐418 ppm ve 47-‐79 ppm bulunmuştur.
ABSTRACT
Chemical properties (including moisture, ash, crude oil, crude protein, crude fibre, total carbohydrate, total phenol and minerals) of completely ripe chestnut (Castanea sativa Mill.) fruits collected from different locations (Aydın, Bursa and Kastamonu) were determined. Total phenol contents of chestnut fruits changed between 21.8-‐24.7 g GAE/100 g extract. The some macro and micro element contents of chestnut fruit were determined by Inductively Coupled Plasma-‐Atomic Emission Spectroscopy (ICP-‐AES). The chestnuts contained different amounts of Ca, Mg, K, P, Na and Zn. These values were found as 2090-‐2710 ppm, 1216-‐1713 ppm, 10719-‐14867 ppm, 1627-‐1849 ppm, 297-‐418 ppm, and 47-‐79 ppm, respectively.
