Sun dried (T. fasciata) was stored with airtight polyethylene bags at room temperature to investigate the changes in physical, chemical, microbiological and sensory characteristics for 90 days. Sensory and physical (water reconstitution, pH) characteristics of dried T. fasciata showed that the product was acceptable up to 60 days of storage. Moisture content of T. fasciata was significantly increased from 15.06% to 17.80% during the storage period. No significant difference was observed in protein, lipid and ash content on dry matter basis during storage. However, amount of lipids of the dried fish was slightly decreased with the increasing of storage time. The pH value of dried T. fasciata was decreased significantly from 6.51 to 5.94 during the storage period. The peroxide value was increased from 13.84 to 27.87 meq/Kg of lipid. Similarly, acid value and conjugated diene of the lipids were increased significantly, and this result suggested that lipid oxidation occurred over this period of time. Microbial load was also increased from 1.13 to 8.37 log CFU/g with the increasing of storage time. Results of this study showed that the product was oxidized marginally during the storage period and suitable for human consumption up to 60 days.

Bahadır Demirel | Hasan Pınar
Dünyada en çok bulunan ve uzun zamandan beri kullanılan birincil enerji kaynağı fosil yakıtlar olup, kullanım miktarına bağlı olarak yakın bir zamanda tükeneceği tahmin edilmektedir. Bu tüketimin bir sonucu olarak küresel ısınma tehlikesi giderek büyümektedir. Bu çevresel tehdidin en büyük kaynağı olan fosil yakıt tüketimini azaltabilmek adına yenilenebilir enerji kaynak kullanımını artırmak, bu çevresel zararı azaltabilmek için büyük bir fırsat oluşturmaktadır. Bu enerji kaynakları içerisinde en büyük potansiyele sahip alternatif enerji kaynağı biyokütledir. Bu çalışmada, ülkemizde özellikle Akdeniz Bölgesinde yoğun olarak yetiştiriciliği yapılan muz bitkisi tarımsal artıklarının enerji kaynağı olarak değerlendirilebilmesi olanakları araştırılmıştır. 2018 yılında 498.888 ton/yıl üretimi yapılan muz bitkisi için tarımsal faaliyetler sonucunda yaklaşık olarak 209.448 ton kuru biyokütle artığı açığa çıkmaktadır ve bu artıkların enerji olarak geri dönüştürüldüğünde ise 987 MW enerji potansiyeline sahip olacağı hesaplanmıştır. Bu potansiyele bağlı olarak muz artıklarının, Türkiye’deki katı biyoyakıt olarak enerjiye dönüştürülebilme olanakları ve ülke ekonomisine katkıda bulunabilirliği tartışılmıştır.
