Farklı keten çeşitlerinin ve türlerinin
protein, yağ, yağ asitleri ve mineral içerikleri karşılaştırıldı. Yabani keten
türünün, Sarı 85 ve Vera çeşidinden daha az yağ içerdiği belirlenmiştir.
Kültür çeşidi olan Sarı 85 ve Vera çeşidinin protein oranı, yabani ketenden
daha yüksek bulunmuştur. Nem oranı ise yabani ketende daha yüksek bulunmuştur.
Keten tohumlarının hepsinde linolenik asit en fazla oranda bulunan yağ asiti olmuştur.
Yağ asitlerinden palmitik, oleik ve linoleik asit keten tohumlarında farklılık
gösterirken, linolenik asit en fazla oranla yabani keten türü ve Sarı 85
çeşidinde bulunmuştur. Yağ asitlerinde n3:n6 oranı en fazla Sarı 85 çeşidinde
hesaplanmıştır. Makro elementler arasında en bol bulunan sırasıyla potasyum,
fosfor, magnezyum ve sodyum olmuştur. Mikro elementler içerisinde ise çinko en
yüksek düzeyde var olan element olup yabani ketende ise bariz bir şekilde
diğerlerinden daha fazla bulunmuştur. Belirlenen elementler arasında P, Na,
Ca, Zn, Ni, Pb elemetleri, yabani keten türünü diğer kültür çeşitlerinden ayırt
edici özelliğe sahip olmuşlardır.
Proximate, fatty acid, and mineral composition of different
flax species and cultivars were compared. Lipid content of wild flax was much
lower than Sarı 85 and Vera cultivars. Protein content of wild flax was also
much lower than Sarı 85 and Vera cultivars. However, moisture content of wild
flax was much higher than Sarı 85 and Vera. Linolenik asit was the major fatty
acid in all flax seeds with a different ratios. Considering the fatty acids,
palmitic, oleic and linoleic acids
showed significant difference (P<0.05) among the flaxseeds samples. Whereas, wild
flax species and Sarı 85 cultivar
contained the highest level of linoleic acid compare to Vera cultivar. Sarı 85 cultivar had highest n3:n6 ratio with
a level of 4.1, and lowest ratio was
observed in Vera cultivar. Amoung the macro elements, K, P, Mg, and Na were pre-dominant elements and Zn was the
most abundant element in the microelements, in particular in wild flaxseed
sample. The elements such as, P, Na, Ca, Zn, Ni and Pb in wild flaxseed were significantly different
from Sarı 85 and Vera cultivars (P<0.05).
