Abstract

The purpose of this study was to develop extruded snack products using a blend of rice flour, corn flour and deoiled rice bran. Effects of feed moisture (12%–18%), barrel temperature (86^⁰C-154 °C) and screw speed (116–284 rpm) on the product properties like lateral expansion (LE), bulk density (BD), water absorption index (WAI), water solubility index (WSI) and hardness (H) were investigated. All these physical properties of extruded snacks were found to be significantly affected by changes in moisture, temperature and screw speed. The regression models for product responses like lateral expansion, bulk density, water absorption index, water solubility index and hardness were highly significant (p ≤ 0.001). The optimized extruded product was obtained at moisture content of 13%, barrel temperature 140 °C, and 203 rpm of screw speed. It was revealed that deoiled rice bran can be incorporated to produce snack products with desirable quality characteristics.

膨化剂的开发及工艺优化对米糠膨化的影响

本研究的目的是利用米粉、玉米粉和去油米糠的混合物开发挤压小吃产品。考察了进料水分(12%-18%)、料筒温度(86⁰C-154 °C)和螺杆转速(116-284 rpm)对产品横向膨胀(LE)、容重(BD)、吸水指数(WAI)、水溶性指数(WSI)和硬度(H)等性能的影响。研究发现，水分、温度和螺杆转速对膨化小吃的这些物理性能都有显著影响。产品横向膨胀、容重、吸水指数、水溶性指数和硬度的回归模型均极显著(p ≤ 0.001)。在水分含量为13%、料筒温度为140 ℃、螺杆转速为203 rpm的条件下，得到了最佳的挤出产品。结果表明，将糠化米糠加工成具有良好品质特性的食品是可行的。
