The present invention discloses a hericium erinaceus yogurt which is composed of the following raw materials in parts by weight: 60-75 parts of fresh milk, 20-24 parts of hericium erinaceus juice, 8-8.5 parts of white granulated sugar, and 4.5-5.5 parts of leavening agent. The hericium erinaceus juice is obtained by adding the hericium erinaceus into 1-1.2 times of deionized water to be boiled for 15 minutes and to filtering the mixture through four layers of gauzes. The hericium erinaceus liquid and the fresh milk are used as raw materials, the white granulated sugar is used as an auxiliary material to conduct preparation, the mixture is sterilized, and lactic acid bacteria are inoculated to the mixture to conduct a lactic acid fermentation to obtain a solidified hericium erinaceus yogurt. The optimum fermentation technology is as follows: the volume percentage of the hericium erinaceus juice is 20%, the mass percentages of the white granulated sugar and the leavening agent inoculum amount are 8% and 5%, respectively, the fermentation temperature is 43 DEG C, and the fermentation time is 4.5 h. The obtained nutritional and health-care product by the above fermentation condition has a unique flavor and the combination of the mellow yogurt flavor and the hericium erinaceus own unique flavor is one of the biggest features of the product.
