摘要: 研究不同天然亲水性胶体及其不同添加量对鲜嫩甜玉米混汁稳定性的影响。采用响应面法,将不同胶体按照设计添加量添加到玉米汁中,通过测定离心前后的吸光度得出稳定系数,以此判断甜玉米混汁的悬浮稳定性。结果表明:结合单因素试验和响应面法分析得出的最佳复配结果为瓜尔豆胶0.07%、亚麻籽胶0.07%、黄原胶0.07%,此时的稳定系数为87.91%。

Abstract: The individual and combined effects of various natural hydrophilic gums on the suspension stability of fresh sweet corn mix juice were studied. In one-factor-at-a-time experiments, the effects of adding guar gum, flaxseed gum, sodium alginate or xanthan gum on the stability factor of sweet corn mix juice, obtained by determining absorbance before and after centrifugation, were evaluated. Subsequently, response surface methodology was employed to investigate the effect of adding guar gum, flaxseed gum and xanthan gum together on the stability factor of sweet corn mix juice, and the optimal amounts of guar gum, flaxseed gum and xanthan gum were all found to be 0.07%, resulting in a stability factor of 87.91%.

Key words: sweet corn mix juice, suspension stability, natural hydrophilic gum
