摘要
随着养殖业的快速发展,蛋白质饲料供应严重不足的问题变得日益突出,而绿色植物是生产叶蛋白最巨大的资源宝库,也是获得叶蛋白最廉价的途径之一。选取草坪草为试验材料,选用料水比、加盐量、p H值和凝聚温度4个因素进行L9(34)的正交试验,以叶蛋白提取率、蛋白质量分数为考察指标,以期获得草坪草叶蛋白提取的最佳优化工艺参数。正交试验表明,草坪草叶蛋白的最佳提取工艺组合为(A3B3C2D1),即料水比1??30、加盐量1.2%、p H值为3.5、絮凝温度为60℃。研究为草坪草叶蛋白的应用开发提供了科学依据。
With the development of animal production, the shortage of protein feed supply has become in-creasingly prominent. But green plants are the most enormous resources treasure of the production of leafprotein, and also one of the more cheap ways to get the protein. In this paper, we select the lawn grass asthe experimental materials. Then through orthogonal test L9（34）,we partly optimize the parameters usingthe leaf protein concentrates（LPC） extraction technology, which are ratio of material to water,salt concen-tration, p H of extracting solution and coagulating temperature. We will obtain the optimized technologi-cal parameters in the leaf protein concentrates extraction technology. The results indicated： in the orthog-onal experiment, the ratio of clove meal to water, p H for extraction solution and coagulation temperaturewere affected LPC extraction ratio respectively. The optimum combination factor for clove extracting LPCwere that 1？？30 for the ratio of material to water, 1.2% for salt concentration, p H 3.5 for extraction solu-tion and 60 ℃ for coagulation temperature. This research studied the optimum extraction technology ofLPC by orthogonal test,so as to provide the theory for the development and application of LPC.
