| Abstract: | Preparation conditions of soybean milk with a special flavor of Chinese date were optimized by orthogonal experiment and variance analysis.In the milk,seven nutritional microelements including Ca,Zn,Fe,Mn,Mg,Cu and K were determined by ICP-AES which was simple and rapid with high sensitivity and accuracy.The recovery were 96.9%—100.5%,and relative standard deviation was less than 2.02%.The results showed that microelements including K,Ca,Mg,Fe and Zn were abundant in the soybean milk with a special flavor of Chinese date and high quality. |
