摘  要:
以我国山西产燕麦为原料,提取并分离纯化燕麦β-葡聚糖,以X-T21型质构仪为主要研究设备,重点研究了β-葡聚糖凝胶性能和相关影响因素。研究结果表明,β-葡聚糖的浓度和分子质量大小会直接影响其凝胶的形成。同时,其凝胶性能受β-葡聚糖浓度、分子质量、pH、溶剂种类和盐等因素的影响。提高β-葡聚糖浓度、分子质量、降低体系pH和添加适量的盐、尿素及硼砂等均有助于其凝胶质构性能的改善;而提高体系pH、增加溶剂种类的极性则会降低其凝胶质构性能。

摘  要:
In this study, the β-glucan was extract and purified from oat of Shanxi . The gelling characteristics and effect factors of oat β-glucan were researched with the X-T21 texture analyser .The results indicate that oat β-glucan gelling was influenced by the concentration and molecular weight of oat β-glucan and the characteristics of oat β-glucan can be effected by the concentration, molecular weight of oat β-glucan, pH and the kind of solvent and so on. The gelling characteristics can be improved by enhancing the concentration, molecular weight of oat β-glucan or decreasing the pH or appending a little salt or urea and borax. On the other hand, the gelling characteristics of oat β-glucan can be decreased by improving pH or appending DMSO.
