Horseradish tree leaf superfine powder production method

The invention discloses a horseradish tree leaf superfine powder production method. The horseradish tree leaf superfine powder production method is characterized in that de-enzyming, cleaning, pulping, homogenizing, spray drying and superfine grinding are performed on fresh horseradish tree leaves to obtain horseradish tree leaf superfine powder. According to the horseradish tree leaf superfine powder production method, the treatment is performed on raw materials in a low temperature superfine grinding mode after the high temperature de-enzyming, normal temperature pulping, homogenizing and spray drying and accordingly the machining time is short, the machining method is simple, and the cost is low; a large amount of energy consumption and nutrient losses due to the fact that a large area of drying place is required by conventional machining to dry leaves or during drying and the effective component decomposition caused by the local high temperature during grinding are avoided; all nutrients and functional components are reserved in the horseradish tree leaf superfine powder and accordingly the bioavailability is greatly improved and a special sharp taste of horseradish trees is removed and accordingly the horseradish tree leaf superfine powder can serve as basic raw materials of subsequent horseradish tree products.
