Öğe Bal arısı (apis mellifera l.) Spermasının taze ve dondurularak muhafaza edilmesi(2016) Gül, Aziz; Ceylan, Durmuş AliArıcılık dünya üzerinde çok eski dönemlerden beri yapılmakta olup çeşitli tarım kolları ile birlikte uyumlu bir şekilde toprağa bağlı kalınmaksızın yapılabilen bir yetiştiricilik koludur. Bilim ve teknolojinin gelişmesi ile yakın geçmişten günümüze balarılarının yaşamları aydınlatılmıştır. Balarılarında üremenin izahı 1845 yılında yapılmış olup, 1926 yılında balarılarında suni tohumlamanın keşfi ile birlikte arıcılık sektörü hızlı bir şekilde ilerlemiştir. Suni tohumlama ile birlikte balarısı spermasının depolanılabilirliği üzerinde çalışmalar da 1960'lı yıllarda başlamıştır. Günümüzde, balarısı sperması taze olarak 16C'de 2 hafta gibi bir süre canlı olarak muhafaza edilebilmektedir. Dondurma işleminde ise tam bir başarı elde edilmiş değildir. Günümüzde depolanmış sperma ile döllenen anaarılarda %50'nin üzerinde işçi arı oranı elde edilmesine rağmen, spermanın saklanması konusunda metotların geliştirilmesine ihtiyaç duyulmaktadırÖğe A comparison of multicriteria decision analysis techniques for determining beekeeping suitability(Springer, 2020) Sarı F.; Ceylan, Durmuş Ali; Özcan, Mehmet Musa; Özcan, Mustafa MeteOver the past decade, the importance of the beekeeping activities has been emphasized in the field of biodiversity, ecosystems, agriculture, and human health. Thus, deciding correct beekeeping activities seems essential to maintain and improve productivity and efficiency. Due to this importance, considering the economic contributions of beekeeping to the rural area, the need for suitability analysis concept has been revealed. At this point, multicriteria decision analysis (MCDA) and geographical information system (GIS) integration provides efficient solutions to the complex structure of decision-making process for beekeeping activities. In this study, site suitability analysis for beekeeping via analytical hierarchy process (AHP), the technique for order of preference by similarity to ideal solution (TOPSIS), and vise kriterijumska optimizacija I kompromisno resenje (VIKOR) was carried out to increase honey productivity and compare MCDA techniques for Konya city in Turkey. Slope, elevation, aspect, distance to water resources, roads and settlements, precipitation, and flora criteria were included to determine suitability. The requirements, expectations, and limitations of beekeeping activities were specified with the participation of experts and stakeholders. The final suitability maps resulted from each method were validated with existing 117 beekeeping locations and Turkish Statistical Institute 2015 beekeeping statistics for Konya province. Considering existing beekeeper locations, AHP has 82%, VIKOR 88%, and TOPSIS 91% overlapping rates with the suitability maps. According to the correlation R values between total beekeeper count and suitability rates, VIKOR has 0.70, TOPSIS 0.68 and AHP 0.66. © 2020, INRA, DIB and Springer-Verlag France SAS, part of Springer Nature.Öğe Determination of antioxidant activity, phenolic compound, mineral contents and fatty acid compositions of bee pollen grains collected from different locations(RESEARCH INST POMOLOGY FLORICULTURE, DIV APICULTURE, 2019) Özcan, Mehmet Musa; Al Juhaimi, Fahad Y.; Babiker, Elfadil E.; Uslu, Nurhan; Ceylan, Durmuş Ali; Ghafoor, Kashif; Özcan, Mustafa Mete; Dursun, Nesim; Ahmed, Isam A. Mohamed; Jamiu, Fadimu Gbemisola; Alsawmahi, Omer N.The objective of the present work was to investigate the influence of locations on bioactive propertiest, phenolic compounds and mineral contents of bee pollens. The oil content of pollen grains changed between 3.50% (Alanya) and 6.85% (Russia-Perm Region). The highest total phenolic content (720 mg/100g) and antioxidant activity values (81.4%) were observed in pollens obtained from the Russia-Perm Region and Alanya districts, respectively. Additionally, the highest carotenoid was found in a pollen sample collected from Karaman (Sanveliler) (98.6 mg/g). The major phenolic compounds were (+)-catechin (66.75-337.39 mg/100g) and quercetin (61.2-1221.7 mg/100g) in all pollen samples. The pollen samples were observed to be a significant source of potassium (3846-6287 mg/kg), phosphorus (2947-5010 mg/kg), calcium (1022-2424 mg/kg) and sulfur (1744-2397 mg/kg). All of the analysis results were significantly affected by supplying locations. The antioxidant activity values of pollens were found partly similar and varied depending on locations. The content of saturated fatty acid (palmitic) was high (20-30%) in the tested pollen samples but did not exceed the content of linoleic acid.Öğe Effect of Inverted Saccharose on Some Properties of Honey(Elsevier Sci Ltd, 2006) Özcan, Musa; Arslan, Derya; Ceylan, Durmuş AliIn this study, three groups of honey [natural honey; honey produced by the supplementary feeding of bees with saccharose syrup (SSH) and heat and acid (88 degrees C, 2 h; 0.1% HCl) treated saccharose syrup honey (ISSH)] were produced and physicochemical (water content, pH, free acidity, ash, HMF, diastase activity, sucrose, protein and viscosity), microbiological and sensory properties of these honeys were determined. Also, mineral contents of the honeys were measured. Moisture and ash contents of SSH were higher, acidity level was lower than those of other honeys. The mineral content of natural honey was higher than that of the others, except for Pb and Zn. Diastase activity of ISSH was below the standard limit and HMF content of this honey was high, but not exceeding the limit. Supplementary feeding of honey bees with inverted (acid and heat treatment) saccharose yielded a honey which had a higher HMF content and a lower diastase activity, moisture content and free acidity than natural honey or SSH.Öğe The investigation of bioactive compounds of wine, grape juice and boiled grape juice wastes(WILEY, 2019) Gülcü, Mehmet; Uslu, Nurhan; Özcan, Mehmet Musa; Gökmen, Fatma; Özcan, Mustafa Mete; Banjanin, Tijana; Gezgin, Sait; Dursun, Nesim; Geçgel, Ümit; Ceylan, Durmuş Ali; Lemiasheuski, ViktarIn this study, bioactive compounds, oil, sugar, fatty acid, and mineral contents of grape wastes (pomace, skin, and seeds) obtained from wine, grape juice, and boilled grape juice production were investigated. Total phenol and tannin contents of grape by-products varied between 31.2 mgGAE/g (molasses skin) and 98.97 mgGAE/g (wine seed); 96.93 mgTAE/g (grape juice pomace) and 138.67 mgTAE/g (molasses pomace), respectively. The highest (377.57 g/kg) and lowest (20.00 g/kg) total sugars were determined in molasses and wine skin wastes, respectively. Epicatechin contents of samples were found between 439.67 mg/kg (molasses skin) and 3,444.57 mg/kg (molasses seed). The lowest and highest linoleic acids were determined in molasses skin oil (40.00%) and grape juice skin oil (51.10%). alpha-Tocopherol contents of wine by-product oils changed between 3.35 mg/kg (seed) and 6.42 mg/kg (pomace). The lowest and highest P contents were determined in molasses skin (17,563 mg/kg) and wine seed (29,634 mg/kg), respectively. Practical applications The residue may represent from 13.5 to 14.5% at the total volume of grapes, and may reach 20%. The most abundant phenolic compound in wine pomace is anthocyanins concentrated in the skin, and flavonols present mostly in the grape seed (56-65% total flavonol). Grape is a phenol-rich plant, and these phenolics are mainly distributed in the skin, stem, leaf, and seed of grape, rather than their juicy middle sections. Skins and seeds of grapes are produced in large quantities by the winemaking industry. These by-products have become valuable raw materials due to their high content of polyphenols, tocols, and other macro- and micronutrients. Seed and skins of grape produced in large quantities by the wine making industry have become valuable raw materials for extraction of polyphenols.Öğe Konya ili için çok ölçütlü karar analizleri ile en uygun arıcılık yerlerinin belirlenmesi(2017) Ceylan, Durmuş Ali; Sarı, FatihArıcılık, günümüzde ülke genelinde önemi giderek artan ve özellikle biyoçeşitlilik, ekosistem, sürdürülebilir tarım ve insan sağlığı alanlarında ön plana çıkmaya başlayan faaliyetlerdendir.
