The invention discloses a dry konjac flying
powder detoxification method, and relates to the technical field of
processing of subsidiary agricultural products. The dry konjac flying
powder detoxification method comprises the following steps of performing detoxification: performing leaching on dry konjac flying
powder with edible
alcohol under a certain condition to remove anti-nutritional factorsand substances in peculiar smell in the konjac flying powder;
drying the detoxified wet konjac flying powder, and performing crushing; passivating the obtained extracting solution, and concentrating the passivated extracting solution; and recovering the
alcohol. Through adoption of the dry konjac flying powder
detoxification method disclosed by the invention, the dry konjac flying powder can be utilized as an
animal feed or raw materials for
food processing; besides, the detoxification of the dry konjac flying powder and the
recovery of konjac
alkaloid are realized, and the productive rate ofthe detoxified konjac flying powder is 80% or above; a three-stage countercurrent soaking extraction technology is adopted, so that the detoxification effect on the konjac flying powder is improved, the
recovery rate of the konjac
alkaloid is increased, the consumption of the edible
alcohol is reduced, and the removal rate of the konjac
alkaloid can be 90% or above; the whole
detoxification process is performed under natural pH and ordinary pressure, and solution pH does not need to be adjusted, so that operation is simplified; and any chemical reagents are not used during production, so thatsafety is high, and the emission of
waste gas, waste water and industrial residues is avoided.
