中文摘要: 该研究以大豆分离蛋白作为成膜基质,添加不同量的亚麻籽胶制备多糖-蛋白复合可食用膜。以机械性能、稳定性、阻隔性、光学性能为测定指标,选用模糊综合评价法进行累计加权,探究亚麻籽胶添加量对大豆分离蛋白膜功能特性的影响。当亚麻籽胶添加量为3%时,膜厚、抗拉强度和断裂伸长率比未添加亚麻籽胶的大豆分离蛋白膜分别提升了80.00%、85.38%、285.78%;氧气透过性、水溶性和透光率降低了27.58%、130.08%、10.06%;其隶属度值为0.282 7,膜的综合性能最佳。
Abstract:In this study,the polysaccharide-protein edible film was prepared from flaxseed gum of different amounts with soy protein isolate as the substrate.With mechanical properties,stability,barrier properties and optical properties as the measurement indicators,fuzzy comprehensive evaluation was used for cumulative weighting to explore the effect of the addition amount of flaxseed gum on the functional properties of the soy protein isolate film.When 3% of flaxseed gum was added,the film thickness,tensile strength,and elongation at break increased by 80.00%,85.38% and 285.78% compared with those of the soy protein isolate film without flaxseed gum,while the oxygen permeability,water solubility,and light transmittance decreased by 27.58%,130.08% and 10.06%.Furthermore,the subordinate value was 0.282 7,indicating the optimal overall performance of the film.
