【摘要】 采用正交试验等方法对淮山提取液 ( DB- Ext)代替羧甲基纤维素钠 ( CMC)作为调配型酸奶稳定剂的效果进行了初步探讨。结果表明 :以原料的 6.0倍水量在 110℃的温度条件下 ,提取 4 0 min,所得的淮山提取液的粘度为 350 0 m Pa·s。添加 50 %的该提取液能完全代替 CMC作为调配型酸奶的稳定剂 ,制得的酸奶稳定性良好更多还原

【Abstract】 This paper studied the technology of preparation of sour milk in which the extract liquid of Dioscorea batatas substituted for CMC as a stabilizer. The result shows that the most suitable condition for extracting liquid of Dioscorea batatas is with 6.0 times of water at 110 ℃ for 40 min, its viscosity is about 3 500 mPa·s. The extract liguid of 50% consistency can replace the CMC completely as a stabilizer, which is added to sour milk with satisfactory stability.更多还原
