Extraction method and extraction system for premixed flour capable of inhibiting glycemic index of food

The invention discloses an extraction method of premixed flour capable of inhibiting the glycemic index of food, which comprises the following steps: respectively putting lucid ganoderma, American ginseng and stigma croci into a wall breaking machine for low-temperature crushing to obtain fine materials; putting the fine material into water, and carrying out low-temperature grinding and water extraction, so that water-soluble substances in the fine material are fully dissolved in water to obtain slurry; filtering the slurry, and taking supernatant liquid; freeze-drying the supernatant to obtain a freeze-dried block; and performing low-temperature powdering on the freeze-dried blocks to obtain the premixed flour capable of inhibiting the food glycemic index, and an extraction system of the premixed flour capable of inhibiting the food glycemic index. According to the invention, extraction of water-soluble substances in ganoderma lucidum, American ginseng and saffron is realized; the extraction device is simple
