Olive is one of the fruits that is mostly consumed in the Mediterranean region. Depending on the variety, oil quality of the olive changes significantly. In this study, Nuclear Magnetic Resonance (NMR), Relaxometry and Magnetic Resonance Imaging (MRI) experiments were used to characterize different Turkish table olive varieties, (Ayvalik, Mega, Sele, Light) in terms of tissue structure, fat and water contents. Moisture and fat content were measured using an infrared moisture analyzer and soxhlet extraction, respectively. NMR Relaxometry and MRI experiments were performed with a 0.32 T and 3T system, respectively. Longitudinal relaxation time (T1) and transverse relaxation time (T2) signals were acquired. Furthermore, non-negative least square (NNLS) method was implemented to T2 decay curves to investigate water and oil distributions. Turbo Spin Echo sequence with fat and water suppression was used for MRI experiments. Significant correlation existed between the physical measurements and NMR relaxation times.

Characterization of Turkish Olive Varieties with NMR Relaxometry and Magnetic Resonance Imaging Experiments Kilercioğlu, Mete; Özel, Barış; Mert, Behiç; Öztop, Halil Mecit (2014-05-23) Olive is the fruit of a tree that grows in Mediterranean climate. Olive grows in the regions of Turkey where Mediterranean climate is dominant. Olive being an important export product for Turkey, the quality of the olive and the products derived from olive has gained significant importance. In this study, Nuclear Magnetic Resonance Relaxometry and Magnetic Resonance Imaging experiments was used to characterize different oil varieties in terms of tissue structure, fat and water contents. Experiments were per...
Active Films Based on Faba Bean (Vicia faba L.) Flour Incorporated with Sumac (Rhus coriaria): Assessment of Antioxidant and Antimicrobial Performances of Packaging for Shelf Life of Chicken Breast Emir, Ayca Aydogdu; Yıldız, Eda; AYDOĞDU, YILDIRIM; Şümnü, Servet Gülüm (2022-11-01) Sumac (Rhus coriaria) cultivated mainly in the Mediterranean region, Eastern and Western North America, South Africa, and Asia is rich in phenolic compounds, especially tannins, anthocyanins, and flavones. For this reason, the sumac extract has the potential to be incorporated in the films that could be used as active packaging material. For that purpose, this study aimed to develop the best biodegradable and eco-friendly active food package made from faba bean flour and sumac extract. To evaluate the films...
Identification of water characteristic similarities in NE Mediterranean Uysal, Zahit; Tuğrul, Süleyman; Kılıç, Ece (null; 2017-10-13) Eastern Mediterranean is known as the most nutrient impoverished basins among the world seas. However, river inputs, atmospheric loads, winter convectional mixing, summer upwelling and the degree of exchange of coastal waters with offshore ones, all, contribute in spatial and temporal heterogeneity in receiving surface waters in the northeastern part of the eastern Mediterranean. This study is conducted to understand similarities in surface waters (inshore (low salinity-high nutrient), transition and offsho...
NMR Relaxometry and magnetic resonance imaging as tools to determine the emulsifying characteristics of quince seed powder in emulsions and hydrogels Alacik Develioglu, Irem; Özel, Barış; Şahin, Serpil; Oztop, Mecit Halil (2020-12-01) Quince seed powder (QSP) is known to exhibit emulsification properties and could be used as a natural emulsifier in colloidal food systems. In this study, emulsion-based alginate hydrogels were formulated using QSP and xanthan gum (XG) as stabilizers. The objective of the study was to show the emulsifying power of QSP in emulsions and their hydrogels using Time Domain (TD) NMR Relaxometry and Magnetic Resonance Imaging (MRI). Rheology and mean particle size measurements for emulsions and scanning electron m...
Antioxidant, antimicrobial activity and phytochemical analysis of Pistacia Vera L. skin Şermet, Muhammed Ömer; Bozoğlu, Faruk; Sağdıçoğlu Celep, A. Gülçin; Department of Biochemistry (2015) Pistacia vera L. commonly grows in Mediterranean region, mainly in the Southeast of Turkey. Traditionally it is used for the treatment of several diseases such as asthma, rheumatism and hypertension. Pistachios are very rich sources of phenolic compounds however the skins are excluded from the nut as waste. This study was designed to investigate the antioxidant and antimicrobial effects of P. vera skin and to evaluate its phenolic compounds. P. vera skin extracts were prepared in different solvents and meth...
