2014
Abbas Moghanizadeh | Mehdi Neshat
Saffron, the dried stigmas of Crocus sativus, is extremely appreciated for its extraordinary color, taste and aroma. At the present time, nearly all the saffron harvest and post harvest processes are carried out manually. To increase the quality and development of economic role of saffron, it is essential to go beyond the traditional method of harvest of saffron. Considering that saffron components terminal velocities are different, a separator is planned and constructed to separate stigma from other parts of saffron flower. This separator is designed on the basis of aerodynamic and physical properties of saffron flower. The purpose of this study is to analyze the performance of a saffron separator for different air flows to increase the level of automation and efficiency of post-harvest operations. The results show that the maximum stigma separation happens when the air flow speed in outlet B is 3 m/s. finally, this data will be applied to find the optimum areas of outlet B and D, as two main parameters which have significant effect on the efficiency of saffron separator.

This study was carried out to determine the influence of diets including different levels of protein and supplemented with probiotic-enzyme mixed on performance parameters and eggshell quality in laying quails. Japanese quails (n=120), 10 wk of age, were divided into 6 dietary treatment groups and the experiment lasted for 10 weeks. In each experiment group there were 5 replicates, and in each replicates there were 4 birds. Six diets, arranged a factorial design with three protein levels (16, 18 and 20 (control) %) and two levels of supplemented probiotic-enzyme mixed (0.0 and 1.0 g/kg) were used. Dietary crude protein levels and supplementation of probiotic-enzyme did not effect on the body weight gain, egg mass, feed intake, feed conversion, cracked egg yield, specific gravity and shell strength. However, egg production, eggshell thickness and eggshell weight were significantly increased by the addition of probiotic-enzymes mixed. Egg weight in group containing 18% crude protein was significantly higher than the containing 16% crude protein group. Results of the present study indicated that laying quails should be fed 18% crude protein and 1.0 g/kg of supplemental probiotic-enzyme mixed improved egg production and eggshell quality.

This study was carried out to reveal the present status of goat farms in Nigde, to detect basic priority problems and to offer some solutions to these problems. For this purpose, a survey was conducted to the goat breeders face to face in randomly selected total 38 goat farms.The survey questions; goat farms and growing core business activities of enterprises that reveals the overall structure, and also the level of satisfaction with the priority issues of breeders are designed to measure. Analyze the results was shown that a large portion of goat breeders (85.0%) were primary school graduates, 5.3%secondery school and also 5.3% high school graduates, goat farms have whole hair goat breed. Goat enterprises have rate of 44.7%, more than 500 goat, 92.1% of goat enterprises go out to highlands, also provided 73.7% of the shepherd's family. In addition, operating revenues were determined come from 50% of goat's milk. Goat breeders were evaluated only 39.5% the form of cheese production, as 60.5% of the cheese, butter, yogurt, and the sale of raw milk of the total milk yield. All business was assessed that owners a profitable goat farming as an occupation and the first five main problems were member alliance, ownership sufficient technical knowledge, serving the technical staff, buck mating and breeding presses, goat shelter, respectively. In addition, it was seen that according to Likert scale, at least the first five issues were satisfied that such as feed, labor, and electricity inputs, product marketing price, sold animals the price, market opportunities related to the sale of manufactured products and finacial supply, respectively. As a result, it could be said that the most important problem for goat enterprises in Nigde province is high production costs and low product prices.

Food labels describe the content of a food and are intended to guide the consumer in food selection. The nutrition information provided must be in consistency with legal requirements and dietary recommendations. Selection of the specific nutrients or food components to be listed should further take into account label space, the analytical feasibility of measuring the particular nutritional component within the food matrix, and the relative costs of such analyses. Information provided on labels should be truthful and not mislead consumers. At the same time, labeling regulations should provide incentives to manufacturers to develop products that promote public health and assist consumers in following dietary recommendations. In some countries some segments of the population benefit from information about the composition of foods. In such cases, countries should consider the need to provide for appropriate labeling and its presentation relative to existing regulations. Different approaches and legal requirements have been established. These create difficulties in developing and harmonizing labels, which have broad international applications. For these reasons, the Codex Guidelines on food labeling play an important role to provide guidance to member countries when they want to develop or update their national regulations and to encourage harmonization of national with international standards. These Guidelines are based on the principle that no food should be described or presented in a manner that is false, misleading or deceptive. Exchange of information at the regional and sub-regional level is important, as each country can learn from the experience of others and regional co-ordination and co-operation can be developed.

Aybegün Ton | Tolga İbrahim Karaköy | Adem Emin Anlarsal
In Turkey, Chickpea is in the first rank in pulses and it is followed by lentil, bean and faba bean respectively. In the world, Turkey is one of the most important producer and exporting countries especially for chickpea and lentil. In recent years, Turkey’s chickpea and lentil production are in downvard trend. Our country has diverse ecological regions for growing many pulses species. Our production potential of pulses must be evaluated and a great importance must be given to the production of cultivars with high yield potential, quality and standart bigness seed. On the other hand, in Turkey, winter chickpea production in coastal region and winter lentil production in central Anatolion region must be widened. Pulses production must be done by using proper growing techniques. Sowing and harvesting should be done by machine. At the same time good war should be made against disease and insect for increasing yield potential of pulses. So, in Turkey, pulses plantation can be increased much more than nowdays.

An experiment was conducted to determine the effect of different combination calcium sources and particle size on performance and egg shell quality in layer hens. In the experiment, 198 brown laying hens at 44 week of age were randomly assigned into 11 treatments groups. The experimental diets consisted of different calcium sources (Fine limestone, large limestone, large oyster shell and large egg shell) and their different combination. The experimental unit consisted of a groups of three hens, thus each treatment was replicated six times. Different calcium sources and particle size addition to the laying hens diet had no significantly effect on body weight gain, egg production, egg mass, feed intake, feed conversion ratio, egg specific gravity, egg shell weight, egg shell thickness and egg shell breaking strength but egg weight had significantly affected by the treatments. The significantly highest egg weight was found in laying hens fed with 50 % fine limestone and 50 % large limestone. Dietary different Ca sources had a significant effect on Ca, P and Mg as mineral contents of eggshell and tibia. In the present study, when dietary large calcium sources (limestone, oyster shell and egg shell) had no effect on performance and eggshell quality parameters in laying hens. However, dietary containing at least 50 % large calcium sources had positive effect on mineral contents of tibia.

In spite of a negative judgements among consumers about meat and meat products, in human nutrition meat and meat products are important for nutrient components which they contain essential nutrients. Intensively produced fermented meat product such as sucuk in our country and lactic acid bacteria (LAB) are used for production of various fermented sausages all over the world. LAB primarily used in order to increase the food safety of such products. LAB with probiotic properties have effect on product taste, flavour and aroma as well as the positive effects on functional and physiological properties. Positive effects of probiotics in human health and product properties in the absence of any adverse effects various cultures have been used for the production of probiotic fermented meat products. In the production of such products prepared dough which have meat and fat in the matrix form a suitable vehicle for probiotic cells. During production of products formation of lactic acid reduced the pH, during ripening conditions water activity reduced so these factors adversely affect viability of probiotic cells. For this reason protecting probiotic cultures from negative effects during exposure in the product and vitality of cells in human gastro-intestinal system to continue operating for consumption to be provided during the order process the cells are coated with microencapsuation. The use of probiotic microorganisms isolated from various foods is being investigated for the production of sausages. Studies on the effects of probiotics on human health of meat products are also needed. In this study the probiotic microorganisms used in the production of probiotic fermented sausages were investigated.
