The aim of this study was to investigate some chemical characteristics and residual nitrite and nitrate levels of sucuk and salami samples collected from retail outlets of major supermarkets in Adana province. A total of 36 sucuk samples (12 brands; 7 national and 5 local producers) and 30 salami samples (10 brands; Macar salamis) were purchased from local markets. Sucuk and salami samples were analyzed for pH value, moisture content, water activity and nitrite and nitrate contents. The average pH values of sucuk samples ranged between 4.69 and 6.56 indicating a higher variation while the average pH values of salami samples ranged between 6.05 and 6.43. Likewise, the average moisture contents of sucuk samples were between 33.56% and 46.78% whereas the average moisture contents of salami samples ranged between 62.09% and 67.91% indicating a relatively lower variation. Water activity values of the sucuk samples were between 0.932 and 0.861 while the average aw values of the salami samples ranged between 0.916 and 0.940. Among the sucuk samples analyzed in the present study mean nitrite and nitrate contents ranged from 58.65 mg/kg to 216.63 mg/kg and 34.86 mg/kg to 161.08 mg/kg, respectively. While relatively lower nitrite (14.30 mg/kg - 35.96 mg/kg) and no nitrate contents were observed in salami samples, the data indicated that a higher variation of both nitrite and nitrate contents were still present in sucuk samples in the local markets requiring more studies and inspections to lower the variation related to dietary exposure to nitrite and nitrite from these types of products.

Tülin Çiçek Rathert | İnan Güven | Fatih Üçkardeş
The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm), chest width (mm) and body length (mm) with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

Aydan Atalar | Nurcan Çetinkaya
Samanların hücre duvarında bulunan lignoselüloz kompleksin parçalanması ile selüloz ve hemiselüloz gibi rumen fermantasyonuyla sindirilebilir fraksiyonlar elde edilir. Rumende sindirilmeyen ligninin biyoteknolojik metotlarla parçalanarak samandan yararlanılabilirliğin artırılması son yıllarda hayvan beslemecilerin odak noktası olan alanlarından birisi olmuştur. Lignoselüloz kompleksin biyolojik metotlarla muamelesinde bakteriler, mantarlar ve bu mikroorganizmalardan elde edilen enzimler kullanılmaktadır. Bakteri muamelesinde Mycobacterium, Arthrobacter ve Flavobacterium türü bakterilerin lignini parçalayabilme özelliğinden yararlanılmaktadır. Enzim muamelesi etkili olmasına rağmen yüksek maliyet nedeniyle uygulamada yer bulamamıştır. Mantar muamelesinde beyaz, kahverengi ve yumuşak çürüme yapan 3 tür mantar kullanılmaktadır. Kahverengi çürükçül mantarlar tercihen selüloz ve hemiselüloza saldırır, ancak lignini parçalayamaz. Beyaz çürükçül mantarlar lignine saldırarak lignol bağları ve aromatik halkayı parçalarlar. Beyaz çürükçül mantarlar selülaz, ksilanaz gibi hidrolitik enzimlerle polisakkaritleri ve lignin peroksidaz ve lakkaz gibi oksidatif ligninolitik enzimlerle lignini parçalarlar. Lignoselülozik materyalleri en iyi parçalayabilen mikroorganizmaların mantarlar olması ve maliyetin düşük olması nedeniyle özellikle beyaz çürükçül mantarların uygulama potansiyeli bulunmaktadır. Bu bildiride biyoçeşitliliğin sağladığı avantajla biyolojik metotlarla samanların sindirilebilirliğinin artırılması tartışılacaktır.

Evrim Güneş Altuntaş | Ebru Deniz | Beycan Ayhan | Kezban Candogan | Duygu Ozel Demiralp
Meat is one of the main nutrition source in the human diet with its excellent protein, vitamin and mineral contents. Despite its advantages, being high-priced makes meat products open to adulteration. Meat products are mixed food types which can contain different species of meat. However, mixing two or more types of meats is not always allowed by laws. On the other hand, replacement high quality meats with cheaper meat types are a cost lowering way for the producers. The commonly consumed meat types differ from country to country, but generally economical, ethnic and religion concerns are in the foreground. In this case, species identification techniques are gaining importance. Although some techniques depending on DNA or spectroscopy have been developed for many years, choosing the best method for species identification is still among the controversial issues today. Thus, the currently used methods and promising techniques in this area were discussed in this review.

Ali Soyuçok | Gülden Başyiğit Kılıç
Günümüzde piyasada bulunan probiyotikler, genellikle fermente süt ürünleri şeklindedir. Süt tüketimi, süt ürünlerinin kolesterol içeriği ve laktoz intoleransı sebebiyle sınırlanmaktadır. Ayrıca, bazı gelişmekte olan ülkelerde fermente ürünlerinin kullanımını kısıtlayan gelenekler ve ekonomik nedenler, alternatif gıdaların probiyotikler için taşıyıcı olarak kullanılması fikrini öne çıkarmaktadır. Bu sebeplerle et ürünleri, tahıllar, baklagiller, meyveler ve sebzeler, probiyotik mikroorganizmaların substratları olarak tüketicilerin ilgisini çekmektedir. Bu ürünlerin geliştirilmesi hem endüstriyel, hem de bilimsel açıdan önemli bir araştırma alanıdır. Bu çalışmada, süt kaynaklı olmayan probiyotik gıdalar hakkında bilgiler verilmiş ve bu alanda yapılan araştırmalar vurgulanmaya çalışılmıştır.
