Also, oil from cold press extraction contained 19.51% and 21.86% linoleic acid for Ferragnes and Tuono almond cultivars, respectively, while 18.74 and 20.51% linoleic acid was recorded in Soxhlet extracted oil from Ferragnes and Tuono almonds, respectively. In addition, alpha-tocopherol contents of the oil samples varied significantly (p<0.05) from 14.18 to 16.86 mg/100 g in Tuono and 15.71-17.96 mg/100 g in Ferragnes for cold-press and soxhlet extracted oils, respectively. beta-Sitosterol composition of the oil obtained by cold press ranged from 157.94 (Tuono) and 171.68 mg/100 g (Cristomorto) while beta-sitosterol content varied from 148.91 (Tuono) and 159.68 mg/100 g (Cristomorto) for oil extracted by Soxhlet method.Öğe 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 Determination of Some Plant Characteristics and Feed Value of Drought-Resistant Mountain Swan (Atriplex nitens)(AGRIMEDIA GMBH, 2019) Acar, Ramazan; Özköse, Abdullah; Kahraman, Oğuzhan; Özbilgin, Abdullah; Özcan, Mehmet Musa; Özcan, Mustafa MeteIn this study we have determined the effect on feed value of different plant characteristics and harvesting times in Mountain Swan (Atriplex nitens), which is resistant to salinity. The effect of row spacing on stem diameter, plant weight and leaf weight was found to be significant (p<0.01 and p<0.05). Although there was no difference in energy values, both row spacing and harvesting times were found to be significant (p<0.05) in terms of dry matter, ash, protein, neutral detergent fiber (NDF) and acid detergent fiber (ADF) values. The highest dry matter content (34.77%) and crude ash (14.92 %) were found in the 40 cm range and the highest crude protein (15.92%) was found in the 20 cm range. The highest NDF (48.02 %), ADF (35.30 %), acid detergent lignin (6.32%) was detected at 60 cm interval. The dry matter ratios which are important for animal nutrition were determined as the highest value at 40, 60 cm row intervals (34.77% and 34.32% respectively) and 36.31% at the 2nd harvest time (03 August 2016). Similar research is needed on this plant. In terms of overall average, dry matter, crude ash, crude protein and crude oil are 33.56%, 14.23%, 14.54% and 1.20%, respectively.Öğe The effect of fermentation process on bioactive properties, essential oil composition and phenolic constituents of raw fresh and fermented sea fennel (Crithmum maritimum L.) leaves(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2019) Özcan, Mehmet Musa; Uslu, Nurhan; Figueredo, Gilles; Al Juhaimi, Fahad; Ghafoor, Kashif; Babiker, Elfadtl E.; Alsawmahi, Omer N.; Özcan, Mustafa Mete; Isam , A.; Ahmed, MohamedThe influence of fermentation on antioxidant activity, total phenol, total flavonoid and phenolic compounds of sea fennel and also volatile compounds of sea fennel essential oil was investigated and compared with fresh samples.

Twenty-six and thirty-three components of sea fennel oils were identified in raw and fermented sea fennel, accounting to about 99.99% and 99.44% of the total oil, respectively. The raw and fermented sea fennel leaves contained 22.31 and 1.32% sabinene, 12.08% and 7.45% limonene, 10.30% and 11.61% beta-phellandrene, 8.59% and 9.17% (Z)-beta-ocimene, 7.08% and 3.55% alpha-pinene, 28.36% and 42.05% gamma-terpinene, 2.57% and 8.64% terpinene-4-ol, respectively. Dominant phenolic compounds were (+)-catechin, gallic acid, 3,4-dihydroxybenzoic acid and p-coumaric acid. Generally, all of the phenolic compounds reduced the effect of microorganisms during,. However, essential oil contents of sea fennel were not effected from fermentation process.Öğe The Effect of Harvest Years on Chemical Composition of Essential Oil of Basil (Ocimum minimum L.) Leaves(TAYLOR & FRANCIS LTD, 2017) Figueredo, Guilles; Özcan, Mehmet Musa; Chalchat, Jean Claude; Chalard, Pierre; Çelik, Battal; Özcan, Mustafa MeteThe essential oils of basil (Ocimum minimum L.) leaves cultivated in Mersin (BuyukeceliGulnar) were extracted by hydrodistillation, and analysed by GC and GC-MS. The major constituents varied depending on harvest years. Linalool, eucalyptol, eugenol and epi-alpha-cadinol were determined as the major components of basil leaves collected between 2003 to 2008 years. The main constituents of oil were linalool (40.22% to 88.34%), eucalyptol (1.46% to 8.87%), eugenol (0.28% to 7.23%) and epi-alpha-cadinol (1.35% to 5.05%) depending on years. The essential oil composition varies qualitatively and/or quantitatively with the time of harvest.Öğe The effect of Heights on Chemical Composition of Essential Oil of Bitter Fennel (Foeniculum vulgare subsp piperitum) fruits(TAYLOR & FRANCIS LTD, 2016) Figueredo, Guilles; Özcan, Mehmet Musa; Al-Juhaimi, Fahad Y.; Chalchat, Jean Claude; Özcan, Mustafa Mete; Chalard, PierreThe essential oils of fruit of Foeniculum vulgare subsp. piperitum (Apiaceae) growing wild in South Anatolia were extracted by hydrodistillation, and analysed by GC and GC-MS. The percentage yields of the essential oils from fruits of bitter fennel harvested in different heights were 2.66 %, 2.0 % and 1.66 %, respectively. The major constituents varied depending on harvest years. The major constituents of bitter fennel fruit were methyl chavicol (estragol), fenchone and limonene. Methyl chavicol contents of oil changed between 50.2 % (600 m height) to 69.2 % (1600 m height). Fenchone contents of samples varied between 6.5 % and 32.8 %. The highest fenchone content was established at the level of 600 m height. While limonene contents of oil were found as 7.1 % and 8.2 % for 600 m and 1600 m heights, respectively, it was determined as 0.37 % for sea level.Öğe Evaluation of the mineral and trace elements of various breads(M H SCHAPER GMBH CO KG, 2018) Harmankaya, Mustafa; Korkmaz, Ayşegül; Özcan, Mehmet Musa; Ceylan, Durmuşali; Akköz, Cengiz; Dursun, Nesim; Özcan, Mustafa MeteBread samples were provided randomly from six bakeries (A, B, C, D, E and F) located in different district Konya in Turkey. While K contents of white bread vary between 157.0 mg/100 g (Bakery-C) and 515 mg/100 g (Bakery-F), K contents of loaf bread changed between 220 mg/100 g (Bakery-D) to 549 nig/100 g (Bakery-F) (p<0.05).

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.
