中文摘要: 对动态高压微射流处理后的火麻仁分离蛋白-黄原胶复合物进行研究,以复合物为乳化剂,亚麻籽油为油相,构建一种低油相(φ=0.26)乳液凝胶,并考察不同复配质量比的火麻仁分离蛋白/黄原胶对乳液凝胶冻融稳定性和贮藏稳定性的影响。结果表明,当火麻仁分离蛋白与黄原胶的复配质量比为1∶1 时,乳液凝胶具有良好的支撑性能、液滴分布形貌均匀、冻融黏弹性良好,并可明显抑制亚麻籽油在贮藏期间脂质过氧化氢、丙二醛、共轭二烯烃和共轭三烯的生成。
Abstract:The hemp seed protein isolate-xanthan gum complex processed by dynamic high-pressure microfluidization served as the emulsifier and linseed oil as the oil phase to prepare emulsion gel with a low oil phase(φ=0.26).In addition,the effects of different mass ratios of hemp seed protein isolate/xanthan gum on the freezethaw and storage stability of emulsion gel were investigated.The results indicated that a mass ratio of 1∶1 between hemp seed protein isolate and xanthan gum provided emulsion gel with excellent stability,evenly distributed droplets,good freeze-thaw viscoelasticity,and a marked inhibition from linseed oil generating lipid hydrogen peroxide,malondialdehyde,conjugated diolefin,and conjugated triene during storage.
