Investigation of Chemical Composition and Nutritional Value of Truffle Mushroom (Tuber nitidum Vittad.)

Truffles are very precious and expensive mushrooms owing to their distinctive aroma and great flavor. The present study was carried out to survey the nutritional value of Tuber nitidum, a wild edible mushroom belonging to Tuber genus. It was analyzed for fatty acid content, phenolic and volatile compounds and amino acid profile. The chemical composition of the studied mushroom species showed that this wild edible fungus is one of a rich phenolic and amino acid source. The characteristic mushroom odor compounds, 1-octen-3-ol (14.81%) and 1-octen-3-one (11.19%), have been also detected. However, it has been reported that p-hydroxy benzoic acid, gentisic acid, vanillic acid were found in ethyl acetate extract as phenolic ingredient. In the lipidic extract, it has been determined that 76.94% linoleic acid (C18:2n6c), 12.38% palmitic acid (C16:0), 6.38% oleic acid (C18:1n9c), 2.54% stearic acid (C18:0). The wild edible mushroom, Tuber nitidum, a wild edible mushroom, may be of value and importance in the food and pharmaceutical industry as a natural healthy product source.

Trüf Mantarının (Tuber nitidum Vittad.) Kimyasal Bileşimi ve Besinsel Değerinin İncelenmesi

Trüfler, karakteristik aromaları ve leziz tadı nedeniyle çok değerli ve pahalı mantarlardır. Bu çalışma Tuber cinsine ait yabani yenilebilir bir mantar olan Tuber nitidum'un besin değerini araştırmak için yürütülmüştür. Yağ asidi içeriği, fenolik ve uçucu bileşikleri ve amino asit profili analiz edildi. Çalışılan mantarın kimyasal bileşimi, bu yabani yenilebilir mantarın zengin fenolik ve amino asit kaynağı olduğunu gösterdi. Karakteristik mantar koku bileşikleri, 1-okten-3-ol (%14.81) ve 1-okten-3-on (%11.19) da tespit edilmiştir. Bununla birlikte, fenolik bileşen olarak etil asetat ekstraktında p-hidroksi benzoik asit, gentisik asit, vanilik asit bulunmuştur. Lipid özütünde, %76.94 linoleik asit (C18:2n6c), %12.38 palmitik asit (C16:0), %6.38 oleik asit (C18:1n9c), %2.54 stearik asit (C18:0) olduğu tespit edilmiştir. Yabani yenilebilir mantar olan Tuber nitidum, doğal sağlıklı bir ürün kaynağı olarak gıda ve ilaç sektöründe bir değer olarak önemlidir.
