摘  要：
为了探讨魔芋葡甘聚糖对阿拉伯树胶凝胶特性的影响,以提高阿拉伯树胶的胶凝性能,降低其在凝胶质食品中的添加量,本研究以魔芋葡甘聚糖(KGM)及阿拉伯树胶(GA)为试验对象,以溶胀温度、底物配比(KGM∶GA)、凝胶时间为影响因子,KGM/GA凝聚凝胶强度为响应值,采用三因素三水平响应面优化设计方法进行处理分析。结果表明,KGM能有效提高GA的凝胶强度;溶胀温度、底物配比(KGM∶GA)、凝胶时间为KGM/GA共混凝聚物凝胶强度的显著影响因子,各因素间两两交互作用对凝聚凝胶强度的影响效果显著,当溶胀温度、底物配比(KGM∶GA)、凝胶时间的数值分别达到49.64℃、81.77%及58.51 min时,模型预测得出最大凝胶强度为839.01 g·mm。经试验优化所得复合凝胶制备工艺可为改善以阿拉伯树胶为原料的食品品质提供一定的理论依据和指导,从而拓宽其在食品领域中的应用。

摘  要：
In order to investigate the effects of konjac glucomannan on gel properties of gum arabic,increase the gel properties of gum arabic,and reduce its addition in gelatinous food konjac glucomannan( KGM) was blended with gum arabic( GA),and swelling temperature,substrate ratio and gel time were chosen as the factors for gel strength of KGM/GA blend system. Response surface optimization design method of three factors and three levels was used to analysis the gel properties effect of KGM on GA. The results showed that KGM can efficiently improve the gel strength of GA.Swelling temperature,substrate ratio and gel time were the significant influencing factors of KGM/GA blend system.Interactions between each two factors had significant effects on gel strength. When swelling temperature,substrate ratio( KGM: GA),gel time at 49. 64℃,81. 77% and 58. 51 min,respectively,model predicted that the maximum gel strength was 839. 01 g·mm. This optimized gel preparation process can provide some theoretical basis and guidance for improving the quality of gum arabic food,and thus,broaden its application in food industry.
