摘　　要：以大豆蛋白、小麦谷朊粉为原料,添加量为0%、2%、4%、6%、8%的酵母抽提物,利用双螺杆高水分挤压技术制备植物蛋白肉,研究不同酵母抽提物添加量对植物蛋白肉理化性质和结构特性的影响。结果显示,随着酵母抽提物添加量的提高,植物蛋白肉的硬度、咀嚼性和内聚性先增加后降低,拉丝效果变得更加良好,颜色变得更浅,滋味变化也较为明显,二级结构中的有序结构略微减少。研究表明,酵母抽提物对植物蛋白肉品质影响较大。Using soybean protein and wheat gluten as raw materials,the vegetable protein meat was prepared by the twin screw high moisture extrusion technology,with the added yeast extract accounting for 0%,2%,4%,6%and 8%,respectively.The effect of different yeast extract addition amounts on the physicochemical proper-ties and structural properties of plant protein meat was studied.It was found that as the yeast extract addition amounts increased,the hardness,chewiness,and cohesion of vegetable protein meat went up and down.Mean-while,the drawing effect became better and the color lighter,with more obvious changes in taste and the slightly reduced ordered structure in the secondary structure.Overall,yeast extract has a great influence on the quality of vegetable protein meat.
