Changes in functional and sensory properties of tarhana prepared by different drying methods were investigated. While tunnel-dried (TD) tarhana had significantly (P < 0.05) higher foaming capacity compared to freeze-dried (FD), home-microwave-oven-dried (HMD) and industrial-microwave-dried (IMD) samples, the FD tarhana showed the highest protein solubility. All tarhana samples exhibited pseudoplastic behavior described by power-law model. The drying methods used appeared to influence water and oil absorption capacities and emulsifying activity of tarhana. Microwave-dried tarhana exhibited higher overall sensory rating and color acceptability.

This study was conducted to determine the effects of row spacing (RS) and irrigation (IR) on protein content, oil content, and fatty acid composition of soybeans grown in the Harran region of Turkey. Oil content of the seed varied from 20.9 to 22.3%. Oil and protein contents were both affected by year. RS and IR affected protein and oil contents significantly (P < 0.01) in both years. RS of 70 cm had the highest protein content, followed by RS of 60, 40, and 50 cm, respectively. IR every 3rd day resulted in the highest level of protein, followed by 6th, 9th, and 12th day irrigation, respectively. The correlation coefficient (r) between protein and oil content was -0.791 in 1998 and -0.721 in 1999. RS (P < 0.01) and IR (P < 0.01) influenced oleic and linoleic acid contents significantly. Interactions of RS and IR were also found to be significant (P < 0.05) for the oleic and linoleic acid contents of soybeans.
