[目的]开发一种即食玉米藕粉.[方法]通过润湿下沉性试验和速溶性试验,分析玉米糊粉的速溶性.通过单因素试验,研究了奶粉添加量、玉米糊粉粉碎粒度、白砂糖添加量、冲调水温水量等因素对产品口感及冲调性的影响.[结果]玉米糊粉在静置和搅拌的条件下,全部润湿下沉的时间分别是6和9s,说明只有玉米糊粉的情况下速溶性不好,需进一步改进.单因素试验表明,玉米糊粉:奶粉:藕粉:白砂糖=37％:30％:18％:15％时得到的产品口感和冲调性最佳.[结论]得到了一种营养价值高且口感好的即食玉米藕粉.%[Objective] To develop a kind of instant powder from com and lotus root. [Method] The solubility of corn and lotus root powder was analyzed by wetting sinking tesl and instant solubility test, and the effects of milk content, particle size, water temperature and quantity on the taste and dissolving quality of product were analyzed by single factor experiment. [ Result] The whole welting sinking time required by the standing and stirred corn powder was 69 s and 9 s, respectively, indicating that the dissolving quality of corn power was bad and should be further improved ; the single factor experiment concluded that both the taste and dissolving quality were at the best stale at the ratio of corn powder: milk powder: lotus root powder: while sugar =37%:30%: 18%: 15%. [Conclusion] An instant corn and lotus root powder with high nutritional value and good taste was developed.
