Today, many chemical modifications are being made to increase the utilization of chitosan and to make the best use of it. In this study, four novel cross-linked chitosan derivatives in the form of hydrogel (CS-L1 CS-L2, CS-L3, and CS-L4) were prepared by the condensation of chitosan with anisole-based phenolic and nonphenolic aromatic dicarbonyls. Structural analyses were performed by elemental analysis (C, H, N), scanning electron microscopy, Fourier transform infrared, 13 C-CP/MAS (cross-polarization, magic angle spinning) nuclear magnetic resonance, powder X-ray diffraction, and thermogravimetric analysis techniques. Metal ion uptake capacities were studied for selected transition-metal cations in aqueous medium. The amount of metal ions was determined by microwave plasma-atomic emission spectroscopy. In addition, the swelling behaviors were investigated at different temperatures (25 and 37 °C) and at different pH values (3, 7, and 10). The order of the selectivity of cross-linked chitosan derivatives toward metal ions was found to be Cu(II) > Cd(II) > Fe(II) > Co(II) > Ni(II). The results showed that the derivatives exhibited the property of hydrogel and suggest that they could be applied in many areas such as metal removing, water removing, and biological applications.

In this study, nutritional value of Firik produced in Hatay region was examined by using four Firik samples collected from local farmers. Amount of protein, ash, moisture, total sugar, fat, salt, raw cellulose and fatty acid profile were determined and estimated values were compared with similar foods such as bulgur and rice. Protein and ash contents of Firik samples were higher than bulgur and rice, while sugar and fat contents were lower. In addition, higher amount of linoleic acid and remarkably adequate amount of linolenic acid generally known as essential fatty acids were obtained. The results showed that Firik produced in Hatay can be considered to use as a reinforcement ingredient for improving nutritional value of daily meals, as it has better nutritional properties than the other resemble carbohydrate-based foods.

The aim of the present study was to investigate the essential oil and fatty acid compositions and antioxidant capacity and total phenolic content of parsley seeds grown in Arsuz/ hatay region. Parsley seeds had a moisture content of 12,6 wt.% and ash content of 6,86 wt.% while the essential oil content of 2,52 wt.% and total lipid content of 8,85 wt.%. The essential oil was analyzed by gas chromatography and thirty two volatile compounds were determined. The composition of fatty acids were also investigated by GC and seven content were determined. The seeds were extracted with methanol for determination of antioxidant capacity and total phenolic content. Total phenol concentration was found 67.25±5.9mg gallic acid equivalent/g of extract powder. DPPH free radical-scavenging activity IC 50 was found as 0,523±12 mg/ ml. From the Trolox calibration curve cupric reducing antioxidant capacity TEACCUPRAC:17,95 μg / mL was found. Results were compared with standard antioxidant compound BHA and BHT.
