2014
Cem Okan Özer | Birol Kılıç
Pink slime is a meat source which is obtained by the separation of meat particles on trimmed fats the use of separation techniques. Pink slime is an important source for meat industry to meet the consumer demands about consumption of low-fat and low-cost meat products. Furthermore, processing of low-value trimming products to high-value products provide a tangible advantage for meat industry. The use of ammonia hydroxide in the process of pink slime caused a concern about consumer health. Since meatball and wieners with high level of pink slime are in school daily diet program, this meat source became important debate issue. In USA, use of pink slime up to 15% in ground beef based products is permitted without specify on the label, but is not sold for direct consumption. Production and consumption of pink slime is strictly prohibited in the European Union. There is no legal regulation on this issue in Turkey. In this review, the manufacturing method and historical development, advantages, disadvantages, applications and result of scientific studies about pink slime are presented.

Nihal Şimşekli | İsmail Sait Doğan
Nowadays usage of dietary fibers in foods has been increasing duo to revealing of health benefits. Beta-glucans found especially in oats and barley, are polysaccharide and source of water-soluble dietary fiber. Positive effects of beta-glucans like healing coronary-heart disease, lowering blood cholesterol level, balancing blood sugar level and preventing obesity, made beta-glucans widespread functional food components for producing various foods. In addition to beneficial physiological effects of beta-glucans, they texturize, gelatinize, emulsify and stabilize the foods. They increase viscosity, replace fat and enhance rheological properties in cereal, meat and dairy products. They are also used to produce packing material depending on their mechanical properties and molecular weights. In this review, effects of addition of cereal based beta-glucans on technological and functional properties of various foods are revealed based on previous studies.

2014
Hasan Arısoy | Zeki Bayramoğlu
Nowadays, meat consuming level is an indicator of development of countries. The reason for this is the importance of animal proteins such as meat, milk and egg in human nutrition. People in Turkey do not get enough animal protein. Increase of meat and meat related product prices is effective on this. The purpose of this study is to bring up the purchase and consume behavior of consumers. Surveys completed in urban areas around city of Ankara are used primarily. Using Main Mass Ratio Based Simple Occurrence Probability Sampling method 338 families were interviewed. Completed surveys were separated into 3 groups; high, middle, low. As a result of the research, expense for food in total income is around %34. This ratio for families with low income is %53, for families with middle income is %35 and for families with high income is %33. It is found that as income levels of consumers raised, food expenses raise as well. But it shows that as income level increases, expense ratio for food decreases. Food reliability is the most effective factor on consumers’ decision of purchase. Studies show doubts of consumers about food reliability. It is understood that legal adjustments are not applied enough. Especially tight food inspections would be positive on consumer behavior.

2014
İsmail Durmuş | Serdar Kamanlı | Yeliz Kaşko Arıcı | Mehmet Akif Özcan
This study was conducted to investigate the hatching parameters differences between the hatching eggs which were controlled or not for fertility at 18th day of embryo development in the hatchery unit. Hatching was conducted with hatching eggs of Atak-S commercial layers parent stocks. Four treatment groups were constituted; 1) 95% fertility, fertility control at 18th day, 2) 95% fertility, no fertility control at 18th day, 3) 75% fertility, no fertility control at 18th day and 4) 50% fertility, no fertility control at 18th day. There were no significant differences between the groups in terms of fertility rate, hatching efficiency hatchability of fertile eggs and early-, middle and late period embryo mortality. Chick quality according to Pasgar score chick quality assessment differed significantly between the treatment groups. The results of the present study indicate that transferring of eggs to the hatcher without fertility control at 18th day of embryo development did not affect the hatching results, but chick quality decreased when the fertility rate decreased below 45%.
