The present invention discloses a fresh honey-fried rhizoma gastrodiae slice and a preparation method thereof. The processing technology of the finished product comprises the following steps: fresh rhizoma gastrodiae is selected and processes of washing, slicing, color protecting, hardening, pre-cooking, three sugar boiling, drying, etc. The preparation method the following advantages: 1, the technology uses the fresh rhizoma gastrodiae as a raw material to process the fresh honey-fried rhizoma gastrodiae slice, maintains nutrients and medicinal effect components in the rhizoma gastrodiae to the maximum extent without losing, and can avoid a problem of contamination of the medicinal material caused by multi-procedure processing; 2, the technology uses the steps of vitamin C color protecting, calcium chloride hardening, honey stir-frying, etc. to treat the fresh rhizoma gastrodiae to play anti-oxidation effects and pharmacodynamic effect-stabilizing effects; 3, the technology directly uses the fresh rhizoma gastrodiae for processing, shortens production cycle, reduces production costs, saves a drying treatment process of the fresh rhizoma gastrodiae, can conduct the processing on the spot, and saves storage and transportation costs of the processed dry rhizoma gastrodiae product; 4, the fresh honey-fried rhizoma gastrodiae slice is long in shelf life and has the shelf life up to12 months when preserved at room temperature in the dark; and 5, the method is suitable for large-scale processing and production of the fresh rhizoma gastrodiae, greatly alleviates dilemma of difficult production, storage and transportation of the rhizoma gastrodiae, and the technology is stable in processes, simple and convenient in production operation and easy for pilot production and industrial production.
