Nem Kontrollü Bir Kamarada Depolanan Baklanın (Vicia faba L.) Sorpsiyon İzotermlerinin Modellenmesi ve Termodinamik Özelliklerinin Belirlenmesi

چکیده
Sabit sıcaklık ve bağıl nem ortamı sağlayan bir kamarada baklanın (Vicia faba L.), sorpsiyon özellikleri; üç farklı sıcaklıkta (25, 35 45 °C) nemi atomizer nemlendirici ile ayarlanarak su aktivitesi değerlerinde (0.1-0.9 aw) incelenmiştir. Elde edilen deneysel verilerden izoterm eğrilerinin, BET buharı izotermleri sınıflandırmasına göre Tip III (J şekilli) özelliğe sahip olduğu bulunmuştur. Belirli aktivitesinde sıcaklığın artması denge içeriği azalma gözlenmiştir. Baklanın tüm aralığında histeresis etki göstermiştir. Sorpsiyon verilerinin matematik modellere uygunluklarının belirlenmesi amacıyla 12 modeli (GAB, BET, Henderson, Oswin, Peleg, Smith, Caurie, Halsey, Ferro-Fontan, Kuhn, Chung-Pfost White-Eiring) kullanılmıştır. En iyi uyumu; adsorpsiyon için Peleg modelinin, desorpsiyon ise modelinin gösterdiği belirlenmiştir. izosterik ısısı, entropisi, yüzey potansiyeli, net integral entalpi entropi gibi enerji gereksiniminin anlaşılmasını termodinamik fonksiyonlar verileri kullanılarak ısısı içeriğindeki artış azalmış saf suyun buharlaşma gizli değerine yaklaşmıştır.

Enhancing faba bean (Vicia faba L.) genome resources
Grain legume improvement is currently impeded by a lack of genomic resources. The paucity of genome information for faba bean can be attributed to the intrinsic difficulties of assembling/annotating its giant (~13 Gb) genome. In order to address this challenge, RNA-sequencing analysis was performed on faba bean (cv. Wizard) leaves. Read alignment to the faba bean reference transcriptome identif...
متن کاملEstablishment of the regeneration system for Vicia faba L.
A reliable regeneration system for faba bean has been difficult to establish and therefore, the genetic improvement of Vicia faba L. was delayed. The paper describes a method of somatic embryo induction in callus of V. faba. Two Egyptian faba bean cultivars 'Giza 2' and '24 Hyto' were used. Callus was induced from epicotyls and shoot tips cultured on MS or Gamborg medium supplemented with 3% su...
متن کاملTrypsin inhibitor activity in the field bean (Vicia faba L.).
Wilson and McNab' reported an increase in live-weight and a reduction in pancreas size of chicks when field beans (Viciu fabu L.) were autoclaved at 120 "C for 30 min. Such effects may be due to the presence in the raw field bean of a trypsin inhibitor analogous to those found in the soyabean and other legumes. Information on the presence of trypsin inhibitors in the field bean and on growth of...
متن کاملMutageneic effects of Kochia indica extract on Vicia faba L
The present study investigate the effect of Kochia indica extract using Vicia faba L assay. All parameters investigated were being affected. Four concentrations of 10, 20, 30 and 40% were applied for three time duration (6, 12, 24 h). The percentage of germination and plant height are dose and time dependent, probably due to alterations in cell cycle. Treated roots were highly affected compared...
متن کاملSucrose Compartmentation in the Palisade Parenchyma of Vicia faba L.
Intracellular sucrose compartmentation in the palisade parenchyma of Vicia faba L. leaflets was investigated by comparing the specific radioactivity of photosynthetically labeled [(14)C]sucrose in samples enriched in vacuole to that in samples enriched in cytoplasm. Brief centrifugation of leaflet punches was used to sediment most of the palisade parenchyma cytoplasm in the adaxial ends of the ...
