Study on the Technology of Turbid White Waxy Corn Juice Drink

Objective] To optimize processing technique of turbid white waxy corn juice drink.Method] Taking whole grains of white waxy corn as raw materials,the turbid juice drink was studied.On the basis of single factor test results,the order of priority and the optimum combination of each factor that affect the sensory quality of turbid white waxy corn juice drink were studied by orthogonal test.Result] The results showed that soft white sugar＇ s suitable dosage was 4％.The order of priority of each factor that affect the precipitation rate of turbid white waxy corn juice drink was tween-80 ＞ CMC-Na ＞ carrageenan ＞ xanthan gum.The order of priority of each factor that affect the sensory quality of turbid white waxy corn juice drink was tween-80 ＞ xanthan gum ＞ CMC-Na ＞ carrageenan.The optimum combinations of each factor were xanthan gum 0.25％,CMC-Na 0.15％,carrageenan 0.10％,tween-80 0.15％.Conclusion] The obtained juice drink has characteristics of moderate sweetness,white color,waxy corn flavor and stability,which is a healthy food for all of people.
