Preparation method of Hovenia acerba Lindl. multi-enzyme complex

The invention discloses a preparation method of a Hovenia acerba Lindl. multi-enzyme complex. The preparation method comprises the following steps: using selenium-rich Hovenia acerba Lindl. and addedpowder as raw materials; carrying out a series of steps including pretreatment of the raw materials, enzymolysis, primary fermentation, primary filtration, secondary fermentation, secondsary filtration and packaging to obtain the Hovenia acerba Lindl. multi-enzyme complex. According to the preparation method of the Hovenia acerba Lindl. multi-enzyme complex, energy substances which are easily absorbed can be provided for human bodies, and symptoms such as weakness and coma are effectively alleviated; because of rich trace elements, electrolyte and acid-base balance of the human body can be effectively maintained; through enzymolysis and oxidative active substances which are produced through secondary fermentation, contents of alcohol dehydrogenase and aldehyde dehydrogenase can be increased and the reaction activi
