玉米麸质中水提阿拉伯木聚糖凝胶的性能研究

Study on the properties of water-extractable corn bran arabinoxylan hydrogel

  • 摘要: 从玉米麸质中提取的水提阿拉伯木聚糖(WEAX),分别使用过氧化物酶(POX)/H2O2体系和漆酶/O2体系为催化剂制备了WEAX凝胶。采用扫描电子显微镜对阿拉伯木聚糖凝胶的结构进行表征,进一步对凝胶的流变性能、热稳定性和溶胀性能进行了研究。发现过氧化物酶/H2O2体系相较于漆酶/O2体系所制备的凝胶,具有更短的凝胶化时间。热稳定性方面,两种凝胶均在大约250℃左右发生分解。同时,由于质子化作用,两种体系的凝胶在盐酸中的溶胀性远小于在水中的溶胀性。 

     

    Abstract: Water-extractable feruloylated arabinoxylan was extracted from corn bran. The oxidative gelation of WEAX was investigated by using peroxidase/H2O2 system and laccase/O2 system as catalyzer, respectively. SEM was used to characterize the structure of lyophilized WEAX hydrogel. Rheology property, thermal property and swelling capacity of WEAX gels were also investigated. The hydrogels prepared by peroxidase/H2O2 oxidative cross-linking, compared to the hydrogels oxidated by laccase/O2 system, showed faster gelation rate. Thermal analysis revealed the decomposition temperature of both kind of WEAX gels at about 250℃. Due to the protonation effect, the swelling of both kind of WEAX gels in HCl solution was lower than in water.
