Treatment of Tonka Beans in High-voltage Static Field

高压静电处理黑香豆试验

Tonka beans were treated in high-voltage static field, extracted with 95% ethanol for 120 hours,( filtrated,) concentrated, dried by anhydrous sodium sulphate, and then analyzed by GC/ MS.

先用高压静电场对黑香豆进行预处理，然后用95%的乙醇将预处理的黑香豆浸泡120h，过滤，用旋转蒸发仪浓缩，用无水硫酸钠干燥后进行GC/MS分析。

The results showed that the main flavor components, dihydrocoumarin and coumarin, in tonka beans were dramatically influenced by high-voltage static field.

结果表明，高压静电场对黑香豆的主要致香成分&香豆素和二氢香豆素有较显著的影响。
