Macit, Emine; Karaoglu, M. Murat; Bakirci, Ihsan
This study was conducted to investigate the effect of various stabilizers on textural properties of set yogurt. Yogurt samples were prepared by using seven various stabilizers such as sodium caseinate, gelatin, carrageenan, xanthan gum, guar gum, locust bean gum and native corn starch. Control group samples were produced without using stabilizer. Textural analyzes were made with a TA-XT2i texture analyzer. As a result of the statistical analysis, it was determined that stabilizer and storage time had a significant effect (p<0.01) on all texture parameters of yogurt samples, the relaxation force values were not affected by only storage period (p>0.05). In conclusion, Nacaseinate was the most suitable stabilizer for yogurt texture compared to all stabilizers. These findings may contribute to the selection of stabilizer material or preparation of stabilizer mixtures that can be used in the production of set type yogurt for developing different textural parameters.

Oruç, Şeref; Yılmaz, Bahadır; Sancak, Kemal
In this study, four novel boron-containing additives were synthesised chemically in the laboratory. The modification was performed by adding the additives, respectively, into asphalt at a certain amount by weight at the same temperature and mixing conditions. The modification mechanism and microstructure of the blends were characterised by Fourier transform infrared spectrometer and scanning electron microscopy. The variation in modified samples in comparison to base asphalt was investigated by performing the penetration, softening point, dynamic shear rheometer, amplitude–frequency–temperature sweeps and rotational viscosity tests. It was observed that the additives increased the softening point, rutting resistance, elastic properties and viscosity of asphalt. The additive synthesised with triazole borate ester octanol-sulphuric acid catalysts gave the most enhancements, relative to base asphalt.
