Gul, Volkan; Gidik, Betul; Sefaoglu, Firat
Sunflower, an oil plant grown in many parts of the world, is capable of growing in many different climatic conditions. It is of great importance to carry out studies on the adaptation of new varieties and to determine the varieties suitable to the ecology of the region in areas where sunflower cultivation is intense. This study was carried out to determine yield and quality characteristics of some sunflower cultivars (SANBROMR, BOSFORA, SYBARBATI, ROSETTA, LG5485, P64LL62, SYGIBRALTAR, P64LC108 P64LE119, P64LP130, P63LE113, 11TR077, ESNIEGARA, ADELYA, and DERAY) under Bayburt providence conditions of Turkey in 2020-2021. It has been determined that there are significant differences between the cultivars for the traits examined. The highest average seed yield (4194.2 kg ha-1) and average linoleic acid content (65.09%) were found for BOSFORA. The highest average oil content ESNIEGARA (48.78%) and average oil yield respectively were obtained from ESNIEGARA (186.02 kg ha-1) and BOSFORA (182.93 kg ha-1) varieties and the highest average oleic acid content was obtained from 11TR077 variety (41.78%). The results of this study emphasized the importance of varieties in sunflower growing. BOSFORA and ESNIEGARA varieties had high yield and quality characteristics in the ecologies of a semi-arid climate.

İncele - MakaleYalnız künye2021EFFECTS OF VERMICOMPOST FERTILIZER ON THE YIELD AND OIL QUALITY IN SUNFLOWER (Helianthus annuus L.) VARIETIES
Gul, Volkan; Gidik, Betul; Girgel, Umit
This study was carried out in 2018 on an experimental field of Bayburt University in order to demonstrate the effect of different doses of vermicompost on the yield and oil quality in oilseed sunflower varieties. The experiments were carried out in randomized full-block design with three replicates. In the experiments, it was found that administering 100 kg da(-1) of vermicompost to the sunflowers yielded the best results in terms of grain yield (130.81 kg da(-1)), fat ratio (48.21%). and fatty acids parameters (saturated fatty acid ratio 15.30%. unsaturated fatty acid ratio 84.71%). In conclusion, we are of the opinion that, although there is an insufficient number of studies on oil crops. with the help of similar future studies in which vermicompost and other organic fertilizers are compounded, a humanand environment-friendly organic production can be realized by increasing the yield as well as the quality.

Akgül, Halil İbrahim; Şengül, Mustafa; Ürkek, Bayram; Kotan, Tuba Erkaya
In this study, the some physicochemical properties, fatty acid compositions and microbiological properties of butter samples were studied. Butter samples (n = 30) were randomly collected from different local markets. Thus, butter samples were evaluated in terms of Turkish regulations, food safety and quality. The mean values of the butter samples for peroxide value (PV), iodine value (IV), saponification value (SV), Polenske value, Reichert-Meissl (RM) and Refractive index (RI) values were determined as 0.85 mEqO2 kg-1, 30.03, 220.09, 1.30, 25.60 and 1.4611, respectively. The moisture and fat values were not in harmony with Turkish Food Codex Butter, Other Milk Fat Based Spreadable Products and Anhydrous Milkfat Notification (the highest moisture content 16%, the lowest fat content 80%) in 23 and 13 butter samples, respectively. The salt values were coherent with Turkish Food Codex in all butter samples. Conjugated linoleic acid (CLA) rate of the butter samples was ranged from 0.15 to 1.32%. The average values of coliforms, total aerobic mesophilic bacteria (TAMB) and mould and yeasts counts were determined as 1.67, 6.33 and 5.22 log CFU g-1, respectively.

This study examined the characteristics of 13 samples from 10 different brands of chocolate spread that are sold in markets in Turkey. Humidity level, oil content, pH value, color values (L*, a*, b*), were determined, chocolate fat samples were tested for free fat acidity rate, peroxide value, iodine value and fat acids composition. The samples composed of 14 different fatty acids. Dominant fatty acids were palmitic acid (9.82-27.19 %), oleic acid (26.27-56.05 %) and linoleic acid (10.87-52.40 %). It was observed that saturated fatty acids (SFA) of the samples ranged between 17.01 and 32.03 %, monounsaturated fatty acids (MUFA) ranged between 19.74 and 57.00 % and polyunsaturated fatty acids (PUFA) ranged between 11.01 and 52.51 %. The analyses showed that contents of the samples complied with legal limits. The types of fatty acids used were determined to be remarkable due to their fatty acids composition.
