摘要: 研究天然亲水性胶体对山药混汁悬浮稳定性的影响。在山药混汁中分别添加不同种类的单一胶体和复配胶作为稳定剂,以样品离心前后的浊度差为评价指标,结合单因素试验和正交试验的方法对山药混汁悬浮稳定性进行研究。结果表明:褐藻酸钠、瓜尔豆胶和果胶三种单体稳定剂分别对山药混汁悬浮稳定性的影响显著,呈现一定的规律性,同时3种胶体复配使用对山药混汁的稳定性有更好的作用。其复配稳定剂用量配方为褐藻酸钠0.17%、瓜尔豆胶0.10%、果胶0.17%。

Abstract: The present study was conducted to test the individual and combined effects of 4 natural hydrophilic colloids such as sodium alginate, guar gum, xanthan gum and pectin on the suspension stability of yam juice, evaluated in terms of turbidity difference before and after sample centrifugation. The results indicated that the individual effects of sodium alginate, guar gum and pectin on the suspension stability of yam juice were statistically significant and regulative. The best suspension stability of yam juice was achieved by using all of them: 0.17% sodium alginate, 0.10% guar gum and 0.17% pectin.

Key words: yam juice, suspension stability, natural hydrophilic colloid
