    This study examined the effects of supplementing defatted coconut flour (DCF) on oxysterols, dietary fiber, physicochemical properties, and sensory attributes of NaCl-substituted beef sausages. The sausages were formulated with either 15% wheat flour (WF) + 2% NaCl (DCF-1); 5% WF + 10% DCF + 2% NaCl (DCF-2); 5% WF + 10% DCF + 0.5% NaCl + 1.5% KCl (DCF-3); or 5% WF + 10% DCF + 0.5% NaCl + 1.5% potassium citrate (DCF-4), and roasted at 180 °C for 25 min. DCF supplementation significantly reduced moisture and increased total, insoluble, and soluble dietary fiber in the sausages. DCF-3 and DCF-4 sausages had lower sodium content (P < 0.05). DCF-1 sausages were lighter and redder (P < 0.05) than the other sausages, except DCF-3. DCF-3 sausages exhibited higher cooking loss compared to the other sausages (P < 0.05). DCF-1 sausages had higher levels of 7-ketocholesterol, 7β-hydroxycholesterol, and total oxysterols, while DCF-4 sausages had the lowest levels of 7-ketocholesterol, 22R-hydroxycholesterol, and total oxysterols (P < 0.05). TBARS values were higher in DCF-1 and DCF-2 sausages than in DCF-3 and DCF-4 sausages. DCF-1 sausages had higher carbonyl content compared to the other formulations. The sensory attributes of DCF-3, DCF-1, and DCF-4 sausages were comparable, but DCF-2 sausages had a better taste than DCF-3 and DCF-4, as well as the highest overall acceptability. In conclusion, DCF supplementation improved the dietary fiber content, oxidative stability, and sensory quality of NaCl-substituted beef sausages. The partial substitution of NaCl with potassium salts lowered sodium content and enhanced oxidative stability in beef sausages.

    Different organic fertilizers has affteted on the residual nutrients for rice growth and yield in the next cropping. Effects of different organic fertilizers on residual nutrients, rice growth and yield were studied. Results indicated that application of cow manure in the previous crop resulted in significant difference in exchangeable potassium (K). Other essential nutrients in soil after application of cow manure and compost residue were at high levels and sufficient for rice growth except for nitrogen (N). Residual cow manure with and without split application gave significantly highest rice tiller number and grain fresh and dry weight compared to the other treatments. Nitrogen uptake in grain and K uptake in straw from the cow manure residue was significantly different from the composted residue. Phosphorus (P) uptake in straw and grain yield of all treatments was not significantly different, relating to high amounts of soil available P. Total zinc (Zn) uptake from residual cow manure soil was also highest. Soil pH after harvesting decreased slightly and total and available P in the control (no organic fertilizer application) were lower than residual organic fertilizer treatments. Exchangeable K and extractable sodium (Na) of residual cow manure were highest in soil after harvesting. Residual cow manure gave high level of K which increased rice growth and yield but also increased accumulation of non-essential elements such as sodium (Na). Results suggested that organic fertilizers produced higher residual nutrients, except N, which were sufficient for rice growth and yield in the next cropping. Residual cow manure gave higher exchangeable K which had a positive effect on rice growth but increased Na accumulation in the soil.
