黑豆不同发芽期VC变化规律研究

Effect of Growing Condition on the Vitamin C Content of Black Soybean Sprouts

采用0.1%的草酸作为流动相,研究用高效液相色谱法测定黑豆不同发芽期VC的含量。通过正交试验分析:当溶液pH值7.5,温度23℃培养7 d时,黑豆芽中VC含量最高,并且黑豆芽的外观品质较好。

The growing condition on the VC content of black soybean sprouts is determined by high performance liquid chromatographywith 0.1% oxalic acid as flow phase.The results indicate by orthogonal design method that the best growing conditions are as follows： the pH value is 7.5,the temperature is 23 ℃,and soaking time is 4 d.
