Bazı bilinçli turistler tarihi mekanları ziyaret, kongre ve fuar turizmi, sağlık ve termal turizm, kış turizmini vs. tercih etmektedirler. Bunun yanında, son yıllarda yoğun kent yaşamından bunalan ve doğal hayata özlem duyan insanlar için turizm seçeneklerine yenileri eklenmiştir. Kırsal turizm olarak adlandırılan bu yeni turizm şekli ülkemiz için yeni filizlenen ve gelecek vaat eden turizm seçeneğidir. Tarım turizmi ise Kırsal turizmin bir koludur. Bu turizm şekli; şehirde yaşayan insanların, kırsal kesimdeki yaşamı daha fazla hissetmeleri ve günlük yaşamlarına daha fazla yansıtmaları, yerel kültürleri yakından tanımaları ve yaşamaları, toprakla ve tarımla yakınlaşmalarını sağlamaktadır. Ayrıca, kırsal nüfusa ek gelir sağlayarak köyden kente göç ve buna bağlı ekonomik, sosyal ve kültürel sorunların azaltılması amacını taşımaktadır.

However, the visitor profile is mostly trip-entertainment based (sea-sun-sand). The busy and stressful city life is increasing the need for holidays for people who yearn for nature and natural life. An emerging type of tourism, called “rural tourism”, is promising tourism option for our country. Agricultural tourism or Agro-tourism is a sub branch of “rural tourism”. Vineyard tourism is considered as the bottom line of agricultural tourism. A long term viticulture in Anatolia for a thousand year leads to the formation of biological diversity. Turkey is among the important countries in the world with its vineyard presence and grape production. The convenient ecological conditions of Turkey created a wide and rich genetic resource for different local varieties. Besides these local varieties, foreign varieties are also widely grown. Therefore, Turkey has a high potential for viniculture and vi...

Olive oil and olive farming has significant economic value both in the national and international arena for Turkey. Olive and olive oil, which are irreplaceable ingredients in our breakfasts, many meals and salads in Turkish kitchen, are the primary source of income for the families in Mudanya. Mudanya has a historical past and it has a significant potential in terms of rural tourism, culture tourism and marine tourism due to its current development and location. Olive and olive oil, which are very important in kitchen tourism, are also potential sources for sustainable rural tourism. The more efficient use of olive and olive oil for these areas will provide significant contributions to the development of Mudanya tourism and to the economic strength of the people of the region.

The water-soluble dry matter, pH, titratable acidity and hydroxymethylfurfural (HMF) content of the samples were determined to be 66.19-80.57%, 3.59-5.23, 0.27-1.81 g 100 g-1 and 5.93-762.22 mg kg-1, respectively. The mean fructose and glucose contents of the pekmez samples were determined to be 28.42 g 100 g-1 and 31.67 g 100 g-1, respectively. The densities and electrical conductivities varied between 1.33-1.43 g cm-3 and 1.96-4.51 mS cm-1, respectively. The content of the macro element K identified in the pekmez samples (4449.86 mg kg-1) was greater than that of Ca (1275.52 mg kg-1), P (369.96 mg kg-1), Mg (344.79 mg kg-1) and Na (119.56 mg kg-1). The pekmez samples have antioxidant activities, ranging between 38.20 to 64.45 μmol TE g-1. Six phenolic compounds, caffeic acid, ellagic acid, ferulic acid, gallic acid, p-coumaric acid and rutin hydrate, were identified in the pekmez samples, and significant differences were observed between samples (P<0.01).

Liquid hydrogen peroxide at 30–35 % concentration was applied for 5, 10, 15 and 20 minutes after vaporizing at 30, 40 and 60 °C. The grapes were stored for 3 months in cold rooms at 0 ± 1 °C, immediately after harvest. At the end of 3 months' storage, 10 and 20 minute-applications of 40 °C vaporized hydrogen peroxide and 5 and 10 minutes applications of 60 °C vaporized hydrogen peroxide gave better results with respect to decrease in microorganisms compared with other applications. In addition, when taste and appearance were considered, a 20 minute application of 40 °C vaporized hydrogen peroxide gave better results than the others in grapes stored for 3 months.ISHS, Sci, Commiss Postharvest Biol & TechnolISHS, Working Grp Postharvest Handling FruitsISHS, Working Grp Postharvest Handling VegetablesISHS, Working Grp Qual OrnamentalsISHS, Working Grp Postharvest Technol Tro

In this study, rose hips were harvested at two different maturity periods. Some of them were then dried naturally and others processed traditionally as rose hip marmalade. Phenolic acids (ellagic acid, ferulic acid, caffeic acid, p-coumaric acid, p-hydroxybenzoic acid, protocatechuic acid), ascorbic acid, flavonols (quercetin, kaempferol,myricetin, (+)-catechin) were detected with LC-ESI-MS/MS (Liquid Chromatography Electrospray Ionization Mass Spectrometry). Mineral compounds (Na, Mg, K, Ca, P) were detected using ICP-OES (Inductively Coupled Plasma Optic Emission Spectroscopy) in fresh and processed rose hip samples. The lycopene level was also determined in the samples. Statistical differences were found in all parameters related to the maturity and processing methods in the observed samples. It was found that quercetin and (+)- catechin were the main phenolic acids.

Catechol oxidase, peroxidase and esterase isoenzyme banding patterns of 29 cultivars made it possible to distinguish between 29 Turkish grape cultivars. It was conculuded that all of the three enzyme systems provided the most usefull data as it was possible to distinguish all 29 grape cultivars.

'Sultani Ç ekirdeksiz' cultivated in Manisa-Alaş ehir in western Turkey, were processed with or without brine. Fresh, brined, and nonbrined leaves (after being subjected to 3 months of fermentation) were sampled and extracted with distilled water under reflux. Antioxidant, anti-inflammatory, and anti-nociceptive activities of the water extracts were investigated using in vitro and in vivo methods. Free radical scavenging activity (1,1-diphenyl-2picrylhydrazyl, DPPH • assay), iron(III) reductive activity (reducing power activity assay), capacity of inhibition of linoleic acid peroxidation (ferric thiocyanate and thiobarbituric acid method), antinociceptive activity (p-benzoquinone-induced abdominal constriction test), and anti-inflammatory activity (carrageenan-induced hind paw edema model) were used to determine biological activities of the extracts. In addition, the contents of total phenolics, flavonoids, and flavonols in the extracts were determined by spectrophotometrical methods. Results were compared with those of ascorbic acid, butylated hydroxytoluene, and gallic acid as reference antioxidants. The extracts of fresh, brined, and nonbrined leaves showed almost the same activity in all antioxidant assays. These extracts inhibited the oxidation of linoleic acid to the same extent as BHT. Compositions of the extracts were analyzed by a reverse phase HPLC-PDA method. The occurrence of hydroxycinnamic acids (e.g., caffeic acid) and flavonoids (e.g., quercetin) was verified in the extracts. The content of total flavonoids as well as quercetin was increased by fermentation.
