| 摘 要： | 研究阴离子交换树脂降低沙棘果汁含酸量的效果。结果显示,D941弱碱性阴离子交换树脂能降低沙棘果汁酸度,升高果汁色值及透光率,对Vc的吸附能力较弱,其可滴定酸表观交换吸附量为2.70g/100mL,吸附平衡时间为3h,适宜工作流量为4BV/h,再生剂NaOH适宜浓度为0.2%,再生周期为4次。D941弱碱性阴离子交换树脂可用于沙棘果汁的降酸。

| Abstract: | To investigate deacidification effect of sea buckthorn juice by anion exchange resins.The results showed that titratable acid of sea buckthorn juice reduce and color value and transmittance increase by D941 anion exchange resins.D941 anion exchange resins have weak adsorption capacity for ascorbic acid,superficial adsorption capacity for titratable acid reach 2.70 mg/100 mL,adsorption equilibrium time is 3 h,optimum work flow is 4 BV/h,NaOH regenerant suitable concentration is 0.2% and regeneration cycle is... |
