The invention provides a yangtao lucid ganoderma composite ferment and a preparation method thereof. The preparation method comprises the following steps of: introducing ganoderma lucidum into fruit which takes the yangtao as a main raw material, and processing to obtain a ferment edible beverage which is higher in nutritive value and better in health-care effect after the processing of fermentation engineering and bio-extraction technologies. The raw material used in the yangtao lucid ganoderma composite ferment is the combination of the yangtao which is enriched in benefit ingredients such as vitamin C, polysaccharide and amino acid and the valuable medicinal and edible fungus, so that the yangtao lucid ganoderma composite ferment has various physiological activities such as antioxidation, stomach and intestine nourishing, the three high disease prevention and treatment, immunity improving and cancer prevention and treatment; the raw materials are treated by an ozone technology, the microorganisms on the surfaces of the raw materials can be effectively killed, the integrity of the raw materials can be guaranteed, and the nutrient substances and the active substances, i.e., the enzyme, can not be influenced; and the bio-extraction of the active substances, i.e., the yangtao, can be realized by adopting a normal-temperature (26-34DEG C) multi-flora, multi-stage and multi-level co-fermentation technology, so that the prepared ferment edible beverage simultaneously comprises the effective active ingredients, i.e., the yangtao and the lucid ganoderma, various probiotics and benefit metabolite of the active ingredients and the probiotics.
