Genetiği Değiştirilmiş Tohum Yağları ve Özellikleri

Günümüzde genetik mühendisliğinin tarımsal uygulamalardaki gelişimi sayesinde yağ bitkilerinde genetik modifikasyonlar yapılarak tohum yağının yağ asidi kompozisyonunu belirlemek olanaklı hale gelmiştir. Dünya'da bitkisel yağ üretiminin yaklaşık olarak 87 milyon ton olduğu bildirilmektedir. Bu üretimin ekonomik değeri ise 40 milyar Amerikan Doları'dır. Yağların insan beslenmesindeki öneminin yanı sıra bitkisel yağ asitleri, sabun, deterjan, gres, biyoyakıt, kozmetik ve boya sanayi için de hammadde niteliğindedir. Bu nedenle bitkisel yağlara olan ilgi son yıllarda giderek artmaktadır. Ayrıca bitkisel üretim fazlası yağın, petrole alternatif olarak kullanılabileceği de belirtilmektedir.

Genetically Modified Crop Oils and Their Properties (Turkish with English Abstract)

Nowadays, with the development of genetically engineering in agricultural applications, it is possible to determine the fatty acid composition of crop oils by genetic modifications. The production of vegetable oil throughout the world is about 87 million metric tons. The value of this production is 40 billion US Dollars. Besides their importance in human nutrition, fatty acids from vegetable oils are also used as raw material for soap, detergents, grease, bio-fuels, cosmetics and paint industries. Thus, there is a recent interest on vegetable oils. In addition, the excess amounts of vegetable oil production can be used as an alternative to petroleum.

Keywords:

Genetic modification, fatty acid, canola, rapeseed, corn, soybean ,
