Soy flour was added at levels of 5%, 10%, and 15% of Hom Nil rice flour for extrusion at 190 °C barrel temperature and 350 rpm screw speed. The extruded snack qualities decreased inversely with soy flour. However, product qualities were considered to be optimised when soy flour at 5% was added. The effect of feed moisture content (15, 17, 19 g (100 g)?1 wb), barrel temperature (150, 170, 190 °C) and screw speed (350, 400, 450 rpm) on physicochemical properties of the snack were then investigated. The physicochemical properties of the product including expansion ratio, density, water absorption index (WAI), water solubility index (WSI) and hardness were evaluated. All properties were related, as linear equations, in terms of feed moisture content, barrel temperature, screw speed with relative correlation (R2) at 0.83–0.94. The snack properties along with consumer acceptance were all highest when the extruded condition were 15 g (100 g)?1 wb feed moisture content, 170 °C of barrel temperature and 450 rpm of screw speed. 相似文献

AbstractFerroelectric Bi2GeO5 glass-ceramics were fabricated using conventional and incorporation method. Glasses have been prepared from BiO1.5-GeO2-BO1.5 ternary glass system by focusing on the region of 59?mol%BiO1.5: 23?mol%GeO2: 18?mol%BO1.5. The resulting glass was analyzed by using differential thermal analysis (DTA) for determining the crystallization temperature (Tp). Then, the prepared glass pieces were heat treated at Tp. Effects of different fabrication methods on structure and electrical of the glass-ceramics were investigated. X-ray diffraction result of all glass-ceramics suggested that the main peak of glass-ceramics matched the orthorhombic structure of the pure Bi2GeO5 phase. Microstructures of the prepared glass-ceramics have been found to change from rod-like crystallites to bulk crystallites on modifying the fabrication method. The Bi2GeO5 glass-ceramics prepared by incorporation method presented higher dielectric constant than those of the Bi2GeO5 glass-ceramics prepared by conventional method. Moreover, the Bi2GeO5 glass-ceramic prepared by incorporation method possesses a large value of Pmax (0.94 µC/cm2) comparing to that of the glass-ceramics prepared by conventional method (Pmax = 0.73 µC/cm2). Thus, this study suggests that the incorporation method can effectively modify the microstructure of Bi2GeO5 glass-ceramics, resulting in the improvement of dielectric and ferroelectric properties. 相似文献
