The seasonal variation of proximate composition and amino acid contents of a green algae Ulva rigida (C.

Öz

Bu çalışmada yeşil deniz alglerinden Ulva rigida’nın mevsimsel olarak besin kompozisyonu (protein, yağ, kül, nem) ve aminoasit içeriklerinin belirlenmesi amaçlanmıştır. Çalışma materyali, İzmir Karşıyaka (Bostanlı) sahili boyunca mevsimsel olarak toplanmış ve tüm analizler üç tekerrürlü yürütülmüştür. Yapılan besin kompozisyonu ve aminoasit analizleri sonucunda, mevsimler arasında önemli farklılıklar tespit edilmiş olup kış mevsiminin protein değerleri ve buna bağlı olarak aminoasit içeriklerinde diğer mevsimlere oranla belirgin artışlar gözlenmiştir. En düşük protein miktarı ilkbahar mevsiminde (%7,64±0,22), en yüksek ise kış mevsiminde (%24,67± 0,37) tespit edilmiştir. Yağ yüzdelerinde de mevsimler arasında farklılıklar belirlenmiş olup sonbaharda artış (%1,20±0,32) görülmüştür. Çalışmada ayrıca esansiyel aminoasitlerinde içinde bulunduğu 18 aminoasit türü protein hidrolizi sonucu tespit edilmiştir. Aminoasitlerden triptofan asit hidrolizi sonucu yıkıma uğradığından dolayı saptanamamıştır. Ulva rigida’da diğer aminoasitlere oranla aspartik asit ve glutamik asit miktarları yüksek seviyede bulunmuştur. Alglerin özellikle tat ve aromalarının oluşumunda önemli rol oynayan bu iki aminoasidin miktarları mevsimler arasında da önemli farklılıklar göstermiştir

Anahtar Kelimeler

Ulva rigida, Aminoasit, Esansiyel aminoasitler, Besin kompozisyonu, Yeşil algler
