Farklı Yabani Brassica Tohumlarının Yağ Asidi Kompozisyonu ve Biyodizel Kalitesi

Her geçen gün artan dünya nüfusu ve gelişen sanayi alanları enerjiye duyulan ihtiyacı da artırmaktadır. Bu durum alternatif ve yenilenebilir enerji kaynaklarını ve bu kaynakların verimli kullanımı konusunu daha değerli kılmaktadır. Bu çalışmada, yabani türlerin biyodizel üretiminde kullanılabilirlik potansiyelini belirlemek amacı ile Türkiye’nin Bayburt ili ekolojik koşullarında yetiştirilen Brassicaceae familyasından S. arvensis, B. nigra ve B. napus tohumlarının biyodizel kalite özellikleri ve GC-MS kullanılarak yağ verimi ve yağ asitleri kompozisyonu bölge için ilk kez belirlenmiştir. Brassicaceae familyasından çalışmada yer alan türlerin yağ verimi %30.29-%46.02 arasında bulunmuştur. Ayrıca linolenik asit (%7.62-%13.70) değerleri en düşük B. napus, en yüksek B. nigra’da belirlenmiştir. Parlama noktası bakımından (194˚C-195˚C) B. napus ve S. arvensis birbirine en yakın türler olduğu görülmüştür. S. arvensis ve B. nigra'nın yağ asidi kompozisyonu ve biyodizel kalite analiz sonuçları B. napus’ a benzer değerlerde bulunmuştur. Yabani türler olan S. arvensis ve B. nigra’nın biyodizel kalite özellikleri ve yağ asitleri kompozisyonu bakımından yenilenebilir enerji üretim potansiyeline sahip olduğu görülmüştür.

Fatty Acid Composition and Biodiesel Quality of Brassica nigra, Brassica napus and Sinapis arvensis Seeds

The increasing world population and developing industrial areas increase the need for energy. This situation makes alternative and renewable energy sources and the efficient use of these sources more valuable. In this study, the seeds of Sinapis arvensis, Brassica nigra, and Brassica napus from Brassicaceae family grown in ecological conditions of Bayburt province of Turkey, to determine the usability potential of wild species in biodiesel production. Biodiesel quality characteristics and oil yield and fatty acid composition were determined for the first time for the region using GC-MS. The oil yield of the species included in the study from the Brassicaceae family was found to be between 30.29% and 46.02%. In addition, linolenic acid (7.62%-13.70%) values were determined the lowest in Brassica napus and the highest in Brassica nigra. In terms of flash point (194˚C-195˚C), B. napus and S. arvensis were the closest species. Fatty acid composition and biodiesel quality analysis results of S. arvensis and B. nigra were similar to B. napus. It has been observed that the wild species S. arvensis and B. nigra have renewable energy production potential in terms of biodiesel quality characteristics and fatty acid composition.
