Common vetch (CV), a leguminous crop cultivated for green manure and fodder rich in protein and starch, is widespread over much area of the northern hemisphere. Its seeds can be used as a protein source to human consumption. CV protein isolates (CVPI) and major protein fractions (CV albumin protein, CVAP; CV globulin protein, CVGP; CV glutelin protein, CVGTP) from 4 samples were investigated the properties to facilitate full use of protein resources. Protein comprises 27.70 %–32.14 % of the dry CV seed weight, which is mainly composed by CVAP (26.79 %–56.12 %) and CVGP (22.78 %–52.42 %). CVPI, CVAP and CVGP mainly presented 7S and 11S components. CVGTP mainly contained the 11S component. They showed difference in thermal properties and surface hydrophobicity. Circular dichroism data showed that α-helix was their major secondary structure. CVPI and major protein fractions exhibited a U-shape protein solubility. CVPI and CVAP had advantages in emulsifying and foaming properties. This study provided novel insights on unexploited sources of CV proteins with interesting characteristics in terms of potential uses as protein-based foods.

野豌豆 (CV) 是一种豆科作物，用于种植绿肥和富含蛋白质和淀粉的饲料，广泛分布于北半球的大部分地区。它的种子可用作人类食用的蛋白质来源。研究了来自 4 个样品的 CV 分离蛋白 (CVPI) 和主要蛋白质组分（CV 白蛋白，CVAP；CV 球蛋白，CVGP；CV 谷蛋白，CVGTP）的性质，以促进蛋白质资源的充分利用。蛋白质占CV种子干重的27.70%~32.14%，主要由CVAP（26.79%~56.12%）和CVGP（22.78%~52.42%）组成。CVPI、CVAP和CVGP主要呈现7S和11S分量。CVGTP主要含有11S成分。它们在热性能和表面疏水性方面表现出差异。圆二色性数据表明，α-螺旋是它们的主要二级结构。CVPI 和主要蛋白质组分表现出 U 形蛋白质溶解度。CVPI和CVAP在乳化和发泡性能方面具有优势。这项研究为未开发的 CV 蛋白质来源提供了新的见解，这些蛋白质在作为蛋白质食品的潜在用途方面具有有趣的特征。
