Evaluation of Barley as Human Food Texte intégral
2013
Mehmet Köten | Sabri Ünsal | Ayhan Atlı
Barley, as animal feed, raw material for malting and human food, constitute an important part among cereal sources in the world. Majority of barley that produced both in Turkey and other countries of the world, is being used as animal feed. Poor baking quality, taste and appearance of barley restricted its use in human nutrition. However, recently high protein, fiber, especially β-glucan and high starch content appeal to food industry. Many scientific researches established that β-glucan, a soluble fiber, has an effect in healing coronary-hearth diseases, lowering blood cholesterol level, balancing blood sugar level, preventing obesity. Being a healthy cereal that can be used in various purposes, and an additive in many food products, barley is considered a very promising cereal, and research to increase possibilities of its use in human nutrition is being increased. In the literature, there has been researches on making noodles, bulgur, kavut (roasted cereal), breakfast cereals. In this study the researches relating to evaluation of barley, importance of which is increased every day, as human food was reviewed.

Muzaffar Ahmad Ganie | Amit Kumar Pal | Nazeer Ahmad
It is now clear that over use of pesticides and intensive management of orchards can lead to drastic declines in apple pollinator abundance and crop failures. During the period of study a grower’s survey was conducted to know about knowledge of farmers on native insect pollinators, pollinator management practices, their perceptions of the importance and utility of native pollinators, and their attitudes regarding pesticide application. Despite of having significant knowledge of managed pollination, only few farmers (2%) adopted supplementary methods of pollination (renting honey bee colonies, hand pollination etc.). In Pulwama, 60% of farmers had knowledge about native insect pollinators and 40% did not have any idea of native pollinators and in case of Shopian, the figures were fifty-fifty i.e. 50% had knowledge about native insect pollinators and 50% were unaware. During the period of investigation, native insect pollinators were sampled from different apple orchards under different management systems in early spring during apple flowering. A total of 17 species of insect pollinators belonging to 11 families and 3 orders_ Hymenoptera, Diptera and Lepidoptera registered their occurrence at all the studied apple orchards of the Kashmir Valley. At all the study sites i.e. apple orchards under different management systems, family Halictidae and Empididae registered their presence as dominant groups. The % family contribution of the former at different orchard types decreased with increase in the intensity of the management system and the % family contribution of the later however, showed a direct relationship with the management system found, i.e. the more intense the system, the more abundant was the group. Other groups in general did not show any greater differences in abundances at different sites studied.

2013
Filiz Uçan | Hatice Aysun Mercimek
Requirement simple technology, low production costs, lack of polluting effects and reliability in terms of health of it is the most important advantages of edible films. Chitosan that extend the shelf life of food and increase the economic efficiency of packaging materials is one of the new materials used for edible films. Chitosan was obtained by deacetylation of chitin which is the most commonly occurred polymer after cellulose in nature, in shells of arthropods such as crab, shrimp, lobster and in cell walls of some bacteria and fungi. Chitosan has the important bioactive properties such as hemostatic, bacteriostatic, fungistatic, spermicidal, anticarcinogenic, anticholesteremic, antacids, antiulcer, wound and bone healing accelerator and stimulating the immune system. As well as these features, the film forming and barrier properties of its, chitosan is made the ideal material for edible films and coatings in antimicrobial characters. Especially, in the protection of qualities and the improving storage times of fruits and vegetables, have been revealed the potential use of chitosan. The coating food with chitosan films reduces the oxygen partial pressure in the package, maintains temperature with moisture transfer between food and its environment, declines dehydration, delays enzymatic browning in fruits and controls respiration. In addition to, chitosan are also used on issues such as the increasing the natural flavour, setting texture, increasing of the emulsifying effect, stabilization of color and deacidification.

Concentrations of selected metals (Cu, Cd, Ni, Pb, Mn, Fe, Zn, Cr and Co) in some ready-to-eat-foods consumed in Nigeria were investigated with a view providing information on the risk associated with the consumption of these products. The concentrations of metals (mg.kg-1) in these ready-to-eat-foods are in the ranges of 2.4 – 5.2 for Cu; 0.1– 0.8 for Cd; 0.7 – 4.0 for Ni; 8.1 – 53.7 for Fe; 8.9 – 20.0 for Zn; 0.1 – 3.8 for Pb; 5.1 – 14.4 for Mn; 0.83 – 21.4 for Cr and 0.20 – 1.32 for Co. The concentrations and estimated intakes of Cd, Ni and Pb in some of these food types exceeded the permissible limits and tolerable daily intake respectively. The target hazard quotients (THQ) for the individual metals indicate levels of concern for Ni, Cd, and Co in some of the ready-to-eat-foods. The combined THQ values for the metals in the examined samples ranged from 1.7 to 10 with significant contributions from Cd, Ni and Co.

Arda Yıldırım | Ergin Öztürk
This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.

Senay Ozgen | Saziye Sekerci
Carrot produced in all seasons and can be consumed as fresh, cooked, boiled, garnish, juice and pickles. There is a great variation in carrot color from light yellow to dark purple-black. Because of the dark purple-black color and the high anthocyanin content, ‘Ereğli Siyahı’ cultivar is commonly used in the industry. However, ‘Ereğli Siyahı’ has wide variation within its population. In this study, the difference among the phytochemical content of ‘Ereğli Siyahı’ sampled grouped based on their interior color has been examined. Carrot roots grown in same field in Eregli, Konya were sampled and collected. Marketable 700 roots were from ‘Eregli Siyahı’ were randomly sampled. Then, the roots were cut in half and separated 11 different groups (G) according to the interior color. Each group was homogenized in 4 replications and samples were prepared for analysis of phytochemicals. Results of the study showed that G7 had the highest phenolic content (1199.23 µg GAE/g fw) while G5 was the group that had the lowest phenolic content (516.54 µg GAE/g fw). Antioxidant capacity was determined using TEAC ve FRAP methods. The highest TEAC (8.54 µg TE/g fw) and FRAP (15.52 µmol TE/g) were observed in G2. However, the lowest TEAC (2.09 µmol TE/g) and FRAP (1.62 µmol TE/g) were found in G5. The percentage of carrot roots was the highest in G2 (%35). The results indicated that there is a great deal of variation for several phytochemical traits within “Ereğli Siyahı”.
