不同品种小麦面筋蛋白的功能性质

Functional Properties of Gluten from Different Wheat Cultivars

  • 摘要: 以10个品种小麦面筋蛋白为研究对象,研究了不同品种小麦面筋蛋白的持水性、持油性等水化性质,以及起泡性、泡沫稳定性和乳化性等表面性质,并分析了面筋蛋白的游离巯基、二硫键和二级结构。结果表明,面筋蛋白的功能特性在不同品种间存在差异。高筋小麦面筋蛋白的持水性、持油性显著高于低筋和中筋小麦面筋蛋白(P<0.05),新麦26和师栾02-1面筋蛋白分别具有最强的持水性和持油性(其值分别为356.58%、392.5%)。测试样品中,低筋小麦面筋蛋白具有高的起泡性和表面疏水性,豫保1号面筋蛋白起泡性高达183.33%,而郑麦103面筋蛋白表面疏水性最强(P<0.05)。不同品种小麦面筋蛋白的游离巯基和二硫键含量不同,高筋小麦面筋蛋白含有较高的二硫键,而低筋小麦面筋蛋白游离巯基含量高。此外,高筋小麦面筋蛋白具有较高比例的α-螺旋结构,而低筋小麦面筋蛋白具有高比例的β-折叠和无规则卷曲结构。本研究结果可为面筋蛋白的精深加工和在具体领域的应用提供一定的科学依据。

     

    Abstract: The glutens obtained from ten different wheat cultivars were employed as materials, and the hydration properties (water and oil holding capacity), and surface properties (foaming ability and foaming stability, emulsifying capacity) of gluten were investigated. Subsequently, available sulfhydryl group, disulfide bond, and secondary structure of gluten were analyzed. The results indicated that the functional properties of gluten were different among cultivars. Both of the water-holding capacity and oil-holding capacity of gluten from high-strength wheat flour were significantly higher than those from low and medium-strength wheat flour (P<0.05). Gluten from Xinmai26 and Shiluan02-1 displayed the highest water holding capacity (356.58%) and oil holding capacity (392.5%), respectively. Gluten from low-strength wheat flour had higher foaming ability and surface hydrophobicity. YubaoNo.1 gluten had the highest foaming property with the value of 183.33%, and Zhengmai103 gluten had the strongest surface hydrophobicity (P<0.05). The contents of free sulfhydryl group and disulfide bond in gluten were also different among cultivars. The content of disulfide bond from high-strength wheat was higher while low-strength wheat had more free sulfhydryl group. Additionally, gluten from high-strength wheat contained the highest ratio of α-helix, while β-sheet and random coil occupied larger in gluten from low-strength wheat. These data would provide scientific basis for the deep-processing and its application in specific fields of gluten protein.
