Fast distilling-acetylcholine spectrophoto method to determine the formaldehyde content in the mushroom
This article studies dsitilling equipment of using the auto protein-measuring instrument, empoly the acetylcholine spectrophoto method to determine the formaldehyde content in the mushroom. As a result, the best measuring condition is: smashing the mushroom sample and separate in by the 20 mesh bolt, then soaking in the water for more than 4h, take 2g of the sample, control the distilling volume at 200 mL.The recycle percent is between 87%~96%.
