Abstract:

以米糠蛋白提取率为指标,通过单因素和正交试验,优选出米糠蛋白的亚临界水萃取工艺参数并对其功能特性评价。结果表明,压力为8.0MPa、体系pH值9.0、萃取温度200℃、水料比15mL/g、提取时间25min时,米糠蛋白提取率达55.9%,其蛋白乳化活性为119.8mL/g,乳化稳定性为81.3min,起泡性为71.5%,起泡稳定性为37.4%,持水性为5.6%,持油性为3.7%,溶解度为68.4%。与碱水浸提法和超声波辅助碱水提取法相比,米糠蛋白的亚临界水萃取法在提取时间和提取率方面均具有明显的优势(碱水提取法和超声波辅助碱水提取法的提取时间和提取率分别为120min、35.6%和30min、48.1%)。
