Erol, Nida Demirtaş
Esansiyel omega-3 çoklu doymamış yağ asitleri (n-3 PUFA'lar) insan sağlığı için hayati öneme sahiptir ve bir dizi rahatsızlığı önler; midyeler bu PUFA'ların iyi bir kaynağıdır. Bu çalışmanın amacı, yağ asidi bileşimini ve besin kalitesi parametrelerini ölçerek zebra midyesinin (Dressiana polymorpha) fonksiyonel bir gıda olarak potansiyelini değerlendirmektir. Zebra midyesi yağında çözücü ekstraksiyonla lipid miktarı, yağ asidi bileşimi ve besin kalitesi endeksleri belirlendi ve zebra midyesinin nutrasötik ve farmasötik olarak potansiyeli değerlendirildi. Zebra midyesi düşük lipid içeriğine rağmen insan sağlığına faydalı olan yağ asidi profilleri gösterdi. Zebra midyesindeki majör yağ asidi grubu SFA'lar olup bunu MUFA ve PUFA grupları izledi. EPA ve DHA miktarlarının toplamı 14.051.36 olarak bulundu. Ayrıca zebra midyesinin n6/n3 oranı 0.09 olarak bulundu. Zebra midyesinin PUFA/SFA oranı 0.36 olarak bulundu. AI, TI ve HH değerleri sırasıyla 0,60, 0,37 ve 1,09'du. Mevcut çalışma, zebra midyelerinin lipid kalitesini ve yararlı yağ asitlerini işlevsel diyet bileşenleri olarak değerlendirmeye işaret etmektedir.

Erol, Nida Demirtaş
Canned and pouched tuna products are available in the markets in different liquid media such as brine, different oils and sauces. Limited information is provided about the pouched tuna products in different liquid media available in the Turkish market and the differences between them. The main purpose of this study is to evaluate the differences between two different tuna packaging methods using different packaging media. The pH values of CW (canned tuna in water) and PW (pouched tuna in water) were found to be lower than the others ((CO (canned tuna in olive oil), CS (canned tuna in sunflower oil), PO (pouched tuna in olive oil,) PS (pouched in sunflower oil)). It was observed that the TBA values of all groups were below the limits of developing objectionable odor/taste. The n-6/n-3 ratio was determined to be quite high in CS and PS. On the other hand, higher eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) contents were found in CW and PW compared to the others (CO, CS, PO, PS). It was determined that the tuna products were safe according to the heavy metal contents of arsenic, mercury, lead and cadmium levels. The L* values of all canned tuna (CO, CS, CW) were found to be significantly higher than those of pouched tuna (PO, PS, PW). The b* values of both CW and PW was found to be lower than the other groups. CW had the lowest overall quality, color and taste scores compared to the others. In this regard, pouched tuna products, especially PW, were recommended for health reasons.

Can, Erkan; Özçiçek, Esin; Erol, Nida Demirtaş; Austin, Brian
There has been much discussion about which is better, farmed (= aquaculture) or wild-caught fish (= capture-fisheries), with supporters and opponents of both approaches. On balance, aquaculture should be the better option because of the ability to control all aspects of production. The result is that farmed products are often cheaper than wild-caught equivalents. However, there are negative aspects to aquaculture, including habitat destruction, for example the removal of mangroves for the construction of shrimp farms, the effect of escapees on native fish populations, and the possible negative impact of pollution from organic material, pathogens and antimicrobial compounds. The use of wild-caught “trash” fish as a source of protein and oil for the diets of carnivorous fish species in aquaculture is unsustainable. In contrast with wild-caught fish, there is greater variability in supply because of overfishing, quotas imposed by governments, and the effects of adverse weather. Moreover, fishing in distant waters is expensive and hazardous. Certainly, the quality of the product is more difficult to control because the history of the catch is largely unknown. However, there are concerns about illegal fishing activities, and the capture of undersized specimens which impacts negatively on future stocking levels. For the forseeable future, there will be roles for both aquaculture and capture-fisheries to meet the increasing global demand for aquatic food.
