Öğe Determination of Fatty Acid Compositions of Some Raisin Cultivars in Turkey(ASIAN JOURNAL OF CHEMISTRY, 2011) Akin, AydinIn this study, total fat content and fatty acid composition of 3 raisin cultivars grown in Konya in Turkey were determined by gas chromatography. Polyunsaturated fatty acids (PUFA) were found to be higher than saturated fatty acid (SFA) and monounsaturated fatty acids (MUFA) in all samples. Palmitic acid was the major saturated fatty acid (15.84-24.23 % of total fatty acids) in all samples. Oleic acid was identified EIS the major monounsaturated fatty acids (9.72-16.01 % of total fatty acids) in all samples. Linoleic acid was the most abundant polyunsaturated fatty acids (47.80-60.74 % of total fatty acids) in all samples. It was shown that the fatty acid composition, omega 3/omega 6 fatty acids ratio and SFA/PUFA ratio between the raisin samples were varied.Öğe Effects of cluster reduction, herbagreen and humic acid applications on grape yield and quality of Horoz Karasi and Gok uzum grape cultivars(ACADEMIC JOURNALS, 2011) Akin, AydinThis study was carried out in 5 BB rootstock grafted on Horoz Karasi and Gok uzum grape varieties (Vitis vinifera L.) during the 2010 growth season. Effects of 1/3 cluster reduction (CR), 1/3 CR + herbagreen (HG) and 1/3 CR + humic acid (HA) applications on grape yield and quality of cultivars were examined. The results showed that 1/3 CR + HA application increased grape yield, berry weight, berry red and blue color intensity values of Horoz Karasi grape variety and 1/3 CR application increased grape yield and maturity index values of Gok uzum grape variety.Öğe Effects of some growth regulating applications on leaf yield, raw cellulose and nutrient element content of the Muskule table grape variety(ACADEMIC JOURNALS, 2011) Akin, AydinThe vine leaf is an important dietary product for human nutrition by virtue of its high nutritious value and low calorie. This study was conducted in the Province of Konya in a vineyard belonging to a producer in the 2010 vegetation period. This study investigated the effects of repetitive applications of herbagreen (HG), humic acid (HA), combined foliar fertilizer (CFF) and HG+CFF performed in the Muskule grape variety grafted on 5 BB rootstock on fresh or pickled leaf size and leaf raw cellulose content. HA application increased leaf area and leaf water content values whereas HG+CFF application increased leaf raw cellulose values. The effects of the application on leaf weight and leaf volume were found to be insignificant. It was observed that leaf blade samples were efficient in terms of N, P, Fe, Mn and Cu content, but deficient in K, Ca, Mg and Zn content.Öğe The Effects of Some Summer Pruning and Humic Substance Applications on The Nutritional Value of 'Alphonse Lavallee' Grape Cultivar(SPRINGER, 2018) Akin, AydinViticulture is an important agricultural branch in Turkey. Grape is the most grown fruit species in Turkey. The study was conducted with 'Alphonse Lavallee' grape variety (Vitis vinifera L.) grown on grafted 1103 Paulsen rootstock in Turkey in 2016. In the study effects of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), Humic Substance Application (HS), 1/3 CTR+ STR, 1/3 CTR+ HS, STR+ HS, 1/3 CTR+ STR+ HS applications on nutritive values were investigated. According to results; the maximum dry matter content 87.64g/100g with HS, 87.76g/100g with 1/3 CTR+ HS, 87.78 with STR+ HS and 87.67 with 1/3 CTR+ STR+ HS applications; the maximum crude protein 3.38g/100g with HS and 3.40g/100g with STR+ HS applications; the maximum crude cellulose 4.46g/100g with HS application; the maximum total sugar content 64.64g/100g with STR and 64.64g/100g with HS applications were obtained. No statistically significant difference was found in terms of crude ash content.Öğe EFFECTS OF VARIOUS CROP LOADS AND LEAF FERTILIZER ON GRAPEVINE YIELD AND QUALITY(TAYLOR & FRANCIS INC, 2012) Akin, Aydin; Dardeniz, Alper; Ates, Fadime; Celik, MustafaCrop loads and leaf fertilizers are highly important for yield and quality of grapevine. This research was conducted in the Konya province of Turkey in 2008 and 2009. The effects of crop loads and leaf fertilizers were investigated on yield and quality of Vitis vinifera L. cv. 'Gok uzum'. The combined leaf fertilizer (TARIS-ZF) significantly increased quality parameters such as berry length, berry weight, maturity index, juice yield and drying index of grapevine. Increasing crop load values (16, 21, and 26 buds/vine) increased fresh grape yield and juice yield; however, maturity index and drying index decreased in comparison to the control. According to these results, it was suggested that to produce a high yield 26 buds/vine pruning and non-fertilization could be utilized or to increase quality parameters 16 buds/vine pruning, and fertilization may be applied on grapevine cultivation.Öğe Effects on Fatty Acid Compositions of Muskule Grape Leaves (Vitis vinifera L.) of Different Harvest Times(ASIAN JOURNAL OF CHEMISTRY, 2012) Akin, Aydin; Citil, Ozcan BarisThe present study, deals with the fatty acid profile in six different harvest times of Muskule grape leaves grown in Turkey. The fatty acid profile was determined using gas chromatography. Twenty eight fatty acids were detected in grape leaf oils. Generally, C 18:1 oleic acid, C 14:0 myristic acid, C 18:0 stearic acid, C 18:2 omega 6 linoleic acid, C 16:0 palmitic acid and C 18:3 omega 3 linolenic acid were found to be the major fatty acids in all dates. The monounsaturated fatty acids were determined at 37.43, 41.43, 45.18, 50.05, 51.75 and 54.96 % in 16.05.2010, 31.05.2010, 16.06.2010, 03.07.2010, 20.07.2010, 07.08.2010, respectively. Monounsaturated fatty acids content was found to be more than the polyunsaturated fatty acid content in all times. Despite of the saturated fatty acid showed a decrease against time; there was an increasement with the monounsaturated fatty acids.Öğe Fatty Acid Compositions of Some Popular Grape Seeds Grown in Turkey(ASIAN JOURNAL OF CHEMISTRY, 2012) Akin, AydinThe present study describes the determination and comparison of fatty acid profile in seeds of four popular wine grape cultivars (Narince, Kalecik Karasi, Okuzgozu and Bogazkere) grown in Turkey. The fatty acid profile was determined using GC. 13 Fatty acids were detected in grape seed oils. The results showed that omega-6 fatty acid level of grape seed from Kalecik Karasi were higher than that of other grape cultivars.Öğe The lactic acid fermentation of three different grape leaves grown in Turkey(BLACKWELL PUBLISHING, 2007) Unver, Ahmet; Ozcan, Musa; Arslan, Derya; Akin, AydinLeaves of three different cultivars of Vitis vinifera L., Eksikara, Hesapali and Siyah pekmezlik were fermented in 10% brine and 10% brine + 1% citric acid concentration for 5 weeks. Percent dry matter, average weight, protein and dimethyl sulfide content of fresh leaves were determined. During the fermentation time, chemical properties of brine (titratable acidity, pH, salt content) were determined at certain intervals. Fresh leaves of Eksikara had the highest amount of dry matter (31.69%), followed by Siyah pekmezlik (27.89%) and Hesapali (25.36%).The protein content of fresh leaves decreased approximately 50% as a result of the fermentation. Fermented Hesapali leaves had the highest (2,955 kcal/100 g), while Siyah pekmezlik leaves had the lowest (2,384 kcal/100 g) energy values. Eksikara leaves in 10% brine + 1% citric acid had the lowest pH value (2.09), while Siyah pekmezlik had the highest pH value (2.57) on the fifth week of the fermentation. The highest titratable acidity was measured in Hesapali (10% brine + 1% citric acid). Hesapali leaves in both types of brine showed the highest taste scores, while Eksikara leaves were preferred for their more acceptable odor. Siyah pekmezlik leaves are not recommended for brining as the fermented leaves of this cultivar obtained the lowest sensory scores.
